37 C.F.R. § 1.2 Business to be transacted in writing.

All business with the Patent and Trademark Office should be transacted in writing. The personal attendance of applicants or their attorneys or agents at the Patent and Trademark Office is unnecessary. The action of the Patent and Trademark Office will be based exclusively on the written record in the Office. No attention will be paid to any alleged oral promise, stipulation, or understanding in relation to which there is disagreement or doubt.

37 C.F.R. § 1.3 Business to be conducted with decorum and courtesy.

Applicants and their attorneys or agents are required to conduct their business with the United States Patent and Trademark Office with decorum and courtesy. Papers presented in violation of this requirement will be submitted to the Director and will not be entered. A notice of the non-entry of the paper will be provided. Complaints against examiners and other employees must be made in correspondence separate from other papers.

37 C.F.R. § 1.4 Nature of correspondence and signature requirements.

(a) Correspondence with the Patent and Trademark Office comprises: (1) Correspondence relating to services and facilities of the Office, such as general inquiries, requests for publications supplied by the Office, orders for printed copies of patents, orders for copies of records, transmission of assignments for recording, and the like, and (2) Correspondence in and relating to a particular application or other proceeding in the Office. See particularly the rules relating to the filing, processing, or other proceedings of national applications in subpart B of this part; of international applications in subpart C of this part; of ex parte reexaminations of patents in subpart D of this part; of supplemental examination of patents in subpart E of this part; of extension of patent term in subpart F of this part; of inter partes reexaminations of patents in subpart H of this part; of international design applications in subpart I of this part; and of the Patent Trial and Appeal Board in parts 41 and 42 of this chapter. (b) Since each file must be complete in itself, a separate copy of every paper to be filed in a patent application, patent file, or other proceeding must be furnished for each file to which the paper pertains, even though the contents of the papers filed in two or more files may be identical. The filing of duplicate copies of correspondence in the file of an application, patent, or other proceeding should be avoided, except in situations in which the Office requires the filing of duplicate copies. The Office may dispose of duplicate copies of correspondence in the file of an application, patent, or other proceeding. (c) Since different matters may be considered by different branches or sections of the Office, each distinct subject, inquiry, or order must be contained in a separate paper to avoid confusion and delay in answering papers dealing with different subjects. Subjects provided for on a single Office or World Intellectual Property Organization form may be contained in a single paper. (d)(1) Handwritten signature. A design patent practitioner must indicate their design patent practitioner status by placing the word “design” (in any format) adjacent to their handwritten signature. Each piece of correspondence, except as provided in paragraphs (d)(2) through (5) and (f) of this section, filed in an application, patent file, or other proceeding in the Office that requires a person's signature, must: (i) Be an original, that is, have an original handwritten signature personally signed, in permanent dark ink or its equivalent, by that person; or (ii) Be a direct or indirect copy, such as a photocopy or facsimile transmission (§ 1.6(d)), of an original. In the event that a copy of the original is filed, the original should be retained as evidence of authenticity. If a question of authenticity arises, the Office may require submission of the original. (2) S-signature. An S-signature is a signature inserted between forward slash marks, but not a handwritten signature as defined by paragraph (d)(1) of this section. An S-signature includes any signature made by electronic or mechanical means, and any other mode of making or applying a signature other than a handwritten signature as provided for in paragraph (d)(1) of this section. Correspondence being filed in the Office in paper, by facsimile transmission as provided in § 1.6(d), or via the USPTO patent electronic filing system as an attachment as provided in § 1.6(a)(4), for a patent application, patent, or a reexamination or supplemental examination proceeding may be S-signature signed instead of being personally signed (i.e., with a handwritten signature) as provided for in paragraph (d)(1) of this section. The requirements for an S-signature under this paragraph (d)(2) of this section are as follows. (i) The S-signature must consist only of letters, or Arabic numerals, or both, with appropriate spaces and commas, periods, apostrophes, or hyphens for punctuation, and the person signing the correspondence must insert his or her own S-signature with a first single forward slash mark before, and a second single forward slash mark after, the S-signature (e.g.,/Dr. James T. Jones, Jr./); and (ii) A patent practitioner (§ 1.32(a)(1)), signing pursuant to § 1.33(b)(1) or (2), must supply their registration number either as part of the S-signature or immediately below or adjacent to the S-signature. The hash (#) character may only be used as part of the S-signature when appearing before a practitioner's registration number; otherwise, the hash character may not be used in an S-signature. A design patent practitioner must additionally indicate their design patent practitioner status by placing the word “design” (in any format) adjacent to the last forward slash of their S-signature. (iii) The signer's name must be: (A) Presented in printed or typed form preferably immediately below or adjacent the S-signature, and (B) Reasonably specific enough so that the identity of the signer can be readily recognized. (3) Electronically submitted correspondence. Correspondence permitted via the USPTO patent electronic filing system may be signed by a graphic representation of a handwritten signature as provided for in paragraph (d)(1) of this section or a graphic representation of an S-signature as provided for in paragraph (d)(2) of this section when it is submitted via the USPTO patent electronic filing system. (4) Additional electronic signatures. Correspondence being filed in the USPTO for a patent application, patent, or other patent proceeding at the USPTO which requires a signature may be signed using an electronic signature that is personally entered by the person named as the signer and of a form specified by the Director. (i) A patent practitioner (§ 1.32(a)(1)), signing pursuant to § 1.33(b)(1) or (2), must supply their registration number either as part of the electronic signature or immediately below or adjacent to the electronic signature. A design patent practitioner must additionally indicate their design patent practitioner status by placing the word “design” (in any format) adjacent to the electronic signature. (ii) The signer's name must be: (A) Presented in printed or typed form preferably immediately below or adjacent to the electronic signature; and (B) Reasonably specific enough so that the identity of the signer can be readily recognized. (5) Certifications—(i) Certification as to the paper presented. The presentation to the Office (whether by signing, filing, submitting, or later advocating) of any paper by a party, whether a practitioner or non-practitioner, constitutes a certification under § 11.18(b) of this subchapter. Violations of § 11.18(b)(2) of this subchapter by a party, whether a practitioner or non-practitioner, may result in the imposition of sanctions under § 11.18(c) of this subchapter. Any practitioner violating § 11.18(b) of this subchapter may also be subject to disciplinary action. See § 11.18(d) of this subchapter. (ii) Certification as to the signature. The person inserting a signature under paragraph (d)(2), (3), or (4) of this section in a document submitted to the Office certifies that the inserted signature appearing in the document is the person's own signature. A person submitting a document signed by another under paragraph (d)(2), (3), or (4) is obligated to have a reasonable basis to believe that the person whose signature is present on the document was actually inserted by that person, and should retain evidence of authenticity of the signature. Violations of the certification as to the signature of another or a person's own signature as set forth in this paragraph (d)(5)(ii) may result in the imposition of sanctions under § 11.18(c) and (d) of this chapter. (6) Forms. The Office provides forms for the public to use in certain situations to assist in the filing of correspondence for a certain purpose and to meet certain requirements for patent applications and proceedings. Use of the forms for purposes for which they were not designed is prohibited. No changes to certification statements on the Office forms (e.g., oath or declaration forms, terminal disclaimer forms, petition forms, and nonpublication request forms) may be made. The existing text of a form, other than a certification statement, may be modified, deleted, or added to, if all text identifying the form as an Office form is removed. The presentation to the Office (whether by signing, filing, submitting, or later advocating) of any Office form with text identifying the form as an Office form by a party, whether a practitioner or non-practitioner, constitutes a certification under § 11.18(b) of this chapter that the existing text and any certification statements on the form have not been altered other than permitted by EFS-Web customization. (e) [Reserved] (f) When a document that is required by statute to be certified must be filed, a copy, including a photocopy or facsimile transmission, of the certification is not acceptable. (g) An applicant who has not made of record a registered attorney or agent may be required to state whether assistance was received in the preparation or prosecution of the patent application, for which any compensation or consideration was given or charged, and if so, to disclose the name or names of the person or persons providing such assistance. Assistance includes the preparation for the applicant of the specification and amendments or other papers to be filed in the Patent and Trademark Office, as well as other assistance in such matters, but does not include merely making drawings by draftsmen or stenographic services in typing papers. (h) Ratification/confirmation/evidence of authenticity: The Office may require ratification, confirmation (which includes submission of a duplicate document but with a proper signature), or evidence of authenticity of a signature, such as when the Office has reasonable doubt as to the authenticity (veracity) of the signature, e.g., where there are variations of a signature, or where the signature and the typed or printed name, do not clearly identify the person signing.

37 C.F.R. § 1.5 Identification of patent, patent application, or patent-related proceeding.

(a) No correspondence relating to an application should be filed prior to receipt of the assigned application number (i.e., U.S. application number, international application number, or international registration number as appropriate). When correspondence directed to the Patent and Trademark Office concerns a previously filed application for a patent, it must identify on the top page in a conspicuous location, the application number (consisting of the series code and the serial number; e.g., 07/123,456), or the serial number and filing date assigned to that application by the Patent and Trademark Office, or the international application number of the international application, or the international registration number of an international design application. Any correspondence not containing such identification will be returned to the sender where a return address is available. The returned correspondence will be accompanied with a cover letter, which will indicate to the sender that if the returned correspondence is resubmitted to the Patent and Trademark Office within two weeks of the mail date on the cover letter, the original date of receipt of the correspondence will be considered by the Patent and Trademark Office as the date of receipt of the correspondence. Applicants may use either the Certificate of Mailing or Transmission procedure under § 1.8 or the Priority Mail Express® procedure under § 1.10 for resubmissions of returned correspondence if they desire to have the benefit of the date of deposit in the United States Postal Service. If the returned correspondence is not resubmitted within the two-week period, the date of receipt of the resubmission will be considered to be the date of receipt of the correspondence. The two-week period to resubmit the returned correspondence will not be extended. In addition to the application number, all correspondence directed to the Patent and Trademark Office concerning applications for patent should also state the name of the first listed inventor, the title of the invention, the date of filing the same, and if known, the group art unit or other unit within the Patent and Trademark Office responsible for considering the correspondence and the name of the examiner or other person to which it has been assigned.

37 C.F.R. § 1.10 Filing of correspondence by Priority Mail Express®.

(a)(1) Any correspondence received by the U.S. Patent and Trademark Office (USPTO) that was delivered by the Priority Mail Express® Post Office to Addressee service of the United States Postal Service (USPS) will be considered filed with the USPTO on the date of deposit with the USPS. (2) The date of deposit with USPS is shown by the “date accepted” on the Priority Mail Express® label or other official USPS notation. If the USPS deposit date cannot be determined, the correspondence will be accorded the USPTO receipt date as the filing date. See § 1.6(a). (b) Correspondence should be deposited directly with an employee of the USPS to ensure that the person depositing the correspondence receives a legible copy of the Priority Mail Express® mailing label with the “date accepted” clearly marked. Persons dealing indirectly with the employees of the USPS (such as by deposit in a Priority Mail Express® drop box) do so at the risk of not receiving a copy of the Priority Mail Express® mailing label with the desired “date accepted” clearly marked. The paper(s) or fee(s) that constitute the correspondence should also include the Priority Mail Express® mailing label number thereon. See paragraphs (c), (d) and (e) of this section. (c) Any person filing correspondence under this section that was received by the Office and delivered by the Priority Mail Express® Post Office to Addressee service of the USPS, who can show that there is a discrepancy between the filing date accorded by the Office to the correspondence and the date of deposit as shown by the “date accepted” on the Priority Mail Express® mailing label or other official USPS notation, may petition the Director to accord the correspondence a filing date as of the “date accepted” on the Priority Mail Express® mailing label or other official USPS notation, provided that: (1) The petition is filed promptly after the person becomes aware that the Office has accorded, or will accord, a filing date other than the USPS deposit date; (2) The number of the Priority Mail Express® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express®; and (3) The petition includes a true copy of the Priority Mail Express® mailing label showing the “date accepted,” and of any other official notation by the USPS relied upon to show the date of deposit. (d) Any person filing correspondence under this section that was received by the Office and delivered by the Priority Mail Express® Post Office to Addressee service of the USPS, who can show that the “date accepted” on the Priority Mail Express® mailing label or other official notation entered by the USPS was incorrectly entered or omitted by the USPS, may petition the Director to accord the correspondence a filing date as of the date the correspondence is shown to have been deposited with the USPS, provided that: (1) The petition is filed promptly after the person becomes aware that the Office has accorded, or will accord, a filing date based upon an incorrect entry by the USPS; (2) The number of the Priority Mail Express® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express®; and (3) The petition includes a showing which establishes, to the satisfaction of the Director, that the requested filing date was the date the correspondence was deposited in the Priority Mail Express® Post Office to Addressee service prior to the last scheduled pickup for that day. Any showing pursuant to this paragraph must be corroborated by evidence from the USPS or that came into being after deposit and within one business day of the deposit of the correspondence in the Priority Mail Express® Post Office to Addressee service of the USPS. (e) Any person mailing correspondence addressed as set out in § 1.1(a) to the Office with sufficient postage utilizing the Priority Mail Express® Post Office to Addressee service of the USPS but not received by the Office, may petition the Director to consider such correspondence filed in the Office on the USPS deposit date, provided that: (1) The petition is filed promptly after the person becomes aware that the Office has no evidence of receipt of the correspondence; (2) The number of the Priority Mail Express® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express®; (3) The petition includes a copy of the originally deposited paper(s) or fee(s) that constitute the correspondence showing the number of the Priority Mail Express® mailing label thereon, a copy of any returned postcard receipt, a copy of the Priority Mail Express® mailing label showing the “date accepted,” a copy of any other official notation by the USPS relied upon to show the date of deposit, and, if the requested filing date is a date other than the “date accepted” on the Priority Mail Express® mailing label or other official notation entered by the USPS, a showing pursuant to paragraph (d)(3) of this section that the requested filing date was the date the correspondence was deposited in the Priority Mail Express® Post Office to Addressee service prior to the last scheduled pickup for that day; and (4) The petition includes a statement which establishes, to the satisfaction of the Director, the original deposit of the correspondence and that the copies of the correspondence, the copy of the Priority Mail Express® mailing label, the copy of any returned postcard receipt, and any official notation entered by the USPS are true copies of the originally mailed correspondence, original Priority Mail Express® mailing label, returned postcard receipt, and official notation entered by the USPS. (f) The Office may require additional evidence to determine if the correspondence was deposited as Priority Mail Express® with the USPS on the date in question. (g) Any person who mails correspondence addressed as set out in § 1.1(a) to the Office with sufficient postage utilizing the Priority Mail Express® Post Office to Addressee service of the USPS, but has the correspondence returned by the USPS due to an interruption or emergency in Priority Mail Express® service, may petition the Director to consider such correspondence as filed on a particular date in the Office, provided that: (1) The petition is filed promptly after the person becomes aware of the return of the correspondence; (2) The number of the Priority Mail Express® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the original mailing by Priority Mail Express®; (3) The petition includes the original correspondence or a copy of the original correspondence showing the number of the Priority Mail Express® mailing label thereon and a copy of the Priority Mail Express® mailing label showing the “date accepted”; and (4) The petition includes a statement which establishes, to the satisfaction of the Director, the original deposit of the correspondence and that the correspondence or copy of the correspondence is the original correspondence or a true copy of the correspondence originally deposited with the USPS on the requested filing date.

(h) Any person who attempts to mail correspondence addressed as set out in § 1.1(a) to the Office with sufficient postage utilizing the Priority Mail Express® Post Office to Addressee service of the USPS, but has the correspondence refused by an employee of the USPS due to an interruption or emergency in Priority Mail Express® service, may petition the Director to consider such correspondence as filed on a particular date in the Office, provided that: (1) The petition is filed promptly after the person becomes aware of the refusal of the correspondence; (2) The number of the Priority Mail Express® mailing label was placed on the paper(s) or fee(s) that constitute the correspondence prior to the attempted mailing by Priority Mail Express®; (3) The petition includes the original correspondence or a copy of the original correspondence showing the number of the Priority Mail Express® mailing label thereon; and (4) The petition includes a statement by the person who originally attempted to deposit the correspondence with the USPS which establishes, to the satisfaction of the Director, the original attempt to deposit the correspondence and that the correspondence or copy of the correspondence is the original correspondence or a true copy of the correspondence originally attempted to be deposited with the USPS on the requested filing date. The Office may require additional evidence to determine if the correspondence was refused by an employee of the USPS due to an interruption or emergency in Priority Mail Express® service. (i) Any person attempting to file correspondence under this section that was unable to be deposited with the USPS due to an interruption or emergency in Priority Mail Express® service which has been so designated by the Director, may petition the Director to consider such correspondence as filed on a particular date in the Office, provided that: (1) The petition is filed in a manner designated by the Director promptly after the person becomes aware of the designated interruption or emergency in Priority Mail Express® service; (2) The petition includes the original correspondence or a copy of the original correspondence; and (3) The petition includes a statement which establishes, to the satisfaction of the Director, that the correspondence would have been deposited with the USPS but for the designated interruption or emergency in Priority Mail Express® service, and that the correspondence or copy of the correspondence is the original correspondence or a true copy of the correspondence originally attempted to be deposited with the USPS on the requested filing date.

Money sent to the Office by mail will be at the risk of the sender, and letters containing money should be registered with the United States Postal Service. (b) Payments of money required for United States Patent and Trademark Office fees may also be made by credit card, except for replenishing a deposit account. Payment of a fee by credit card must specify the amount to be charged to the credit card and such other information as is necessary to process the charge, and is subject to collection of the fee. The Office will not accept a general authorization to charge fees to a credit card. If credit card information is provided on a form or document other than a form provided by the Office for the payment of fees by credit card, the Office will not be liable if the credit card number becomes public knowledge. (c) A fee transmittal letter may be signed by a juristic applicant or patent owner.

37 C.F.R. § 1.25 Deposit accounts.

(a) For the convenience of attorneys, and the general public in paying any fees due, in ordering services offered by the Office, copies of records, etc., deposit accounts may be established in the Patent and Trademark Office upon payment of the fee for establishing a deposit account (§ 1.21(b)(1)). A minimum deposit of $1,000 is required for paying any fees due or in ordering any services offered by the Office. However, a minimum deposit of $300 may be paid to establish a restricted subscription deposit account used exclusively for subscription order of patent copies as issued. At the end of each month, a deposit account statement will be rendered. A remittance must be made promptly upon receipt of the statement to cover the value of items or services charged to the account and thus restore the account to its established normal deposit. An amount sufficient to cover all fees, services, copies, etc., requested must always be on deposit. Charges to accounts with insufficient funds will not be accepted. A service charge (§ 1.21(b)(2)) will be assessed for each month that the balance at the end of the month is below $1,000. For restricted subscription deposit accounts, a service charge (§ 1.21(b)(3)) will be assessed for each month that the balance at the end of the month is below $300. (b) Filing, issue, appeal, international-type search report, international application processing, international design application fees, petition, and post-issuance fees may be charged against these accounts if sufficient funds are on deposit to cover such fees. A general authorization to charge all fees, or only certain fees, set forth in §§ 1.16 through 1.18 to a deposit account containing sufficient funds may be filed in an individual application, either for the entire pendency of the application or with a particular paper filed. A general authorization to charge fees in an international design application set forth in § 1.1031 will only be effective for the transmittal fee (§ 1.1031(a)). An authorization to charge fees under § 1.16 in an international application entering the national stage under 35 U.S.C. 371 will be treated as an authorization to charge fees under § 1.492. An authorization to charge fees set forth in § 1.18 to a deposit account is subject to the provisions of § 1.311(b). An authorization to charge to a deposit account the fee for a request for reexamination pursuant to § 1.510 or 1.913 and any other fees required in a reexamination proceeding in a patent may also be filed with the request for reexamination, and an authorization to charge to a deposit account the fee for a request for supplemental examination pursuant to § 1.610 and any other fees required in a supplemental examination proceeding in a patent may also be filed with the request for supplemental examination. An authorization to charge a fee to a deposit account will not be considered payment of the fee on the date the authorization to charge the fee is effective unless sufficient funds are present in the account to cover the fee. (c) A deposit account holder may replenish the deposit account by submitting a payment to the United States Patent and Trademark Office. A payment to replenish a deposit account must be submitted by one of the methods set forth in paragraphs (c)(1), (c)(2), or (c)(3) of this section. (1) A payment to replenish a deposit account may be submitted by electronic funds transfer through the Federal Reserve Fedwire System, which requires that the following information be provided to the deposit account holder's bank or financial institution: (i) Name of the Bank, which is Treas NYC (Treasury New York City); (ii) Bank Routing Code, which is 021030004; (iii) United States Patent and Trademark Office account number with the Department of the Treasury, which is 13100001; and (iv) The deposit account holder's company name and deposit account number. (2) A payment to replenish a deposit account may be submitted by electronic funds transfer over the Office's Internet Web site (www.uspto.gov). (3) A payment to replenish a deposit account may be addressed to: Mail Stop Deposit Accounts, Director of the United States Patent and Trademark Office, P.O. Box 1450, Alexandria, Virginia 22313-1450.

37 C.F.R. § 1.26 Refunds.

(a) The Director may refund any fee paid by mistake or in excess of that required. A change of purpose after the payment of a fee, such as when a party desires to withdraw a patent filing for which the fee was paid, including an application, an appeal, or a request for an oral hearing, will not entitle a party to a refund of such fee. The Office will not refund amounts of twenty-five dollars or less unless a refund is specifically requested, and will not notify the payor of such amounts. If a party paying a fee or requesting a refund does not provide the banking information necessary for making refunds by electronic funds transfer (31 U.S.C. 3332 and 31 CFR part 208), or instruct the Office that refunds are to be credited to a deposit account, the Director may require such information, or use the banking information on the payment instrument to make a refund. Any refund of a fee paid by credit card will be by a credit to the credit card account to which the fee was charged. (b) Any request for refund must be filed within two years from the date the fee was paid, except as otherwise provided in this paragraph or in § 1.28(a). If the Office charges a deposit account by an amount other than an amount specifically indicated in an authorization (§ 1.25(b)), any request for refund based upon such charge must be filed within two years from the date of the deposit account statement indicating such charge, and include a copy of that deposit account statement. The time periods set forth in this paragraph are not extendable. (c) If the Director decides not to institute a reexamination proceeding in response to a request for reexamination or supplemental examination, fees paid with the request for reexamination or supplemental examination will be refunded or returned in accordance with paragraphs (c)(1) through (c)(3) of this section. The reexamination requester or the patent owner who requested a supplemental examination proceeding, as appropriate, should indicate the form in which any refund should be made (e.g., by check, electronic funds transfer, credit to a deposit account). Generally, refunds will be issued in the form that the original payment was provided. (1) For an ex parte reexamination request, the ex parte reexamination filing fee paid by the reexamination requester, less the fee set forth in § 1.20(c)(7), will be refunded to the requester if the Director decides not to institute an ex parte reexamination proceeding. (2) For an inter partes reexamination request, a refund of $7,970 will be made to the reexamination requester if the Director decides not to institute an inter partes reexamination proceeding. (3) For a supplemental examination request, the fee for reexamination ordered as a result of supplemental examination, as set forth in § 1.20(k)(2), will be returned to the patent owner who requested the supplemental examination proceeding if the Director decides not to institute a reexamination proceeding.

37 C.F.R. § 1.27 Definition of small entities and establishing status as a small entity to permit payment of small entity fees; when a determination of entitlement to small entity status and notification of loss of entitlement to small entity status are required; fraud on the Office.

(a) Definition of small entities. A small entity as used in this chapter means any party (person, small business concern, or nonprofit organization) under paragraphs (a)(1) through (a)(3) of this section. (1) Person. A person, as used in paragraph (c) of this section, means any inventor or other individual (e.g., an individual to whom an inventor has transferred some rights in the invention) who has not assigned, granted, conveyed, or licensed, and is under no obligation under contract or law to assign, grant, convey, or license, any rights in the invention. An inventor or other individual who has transferred some rights in the invention to one or more parties, or is under an obligation to transfer some rights in the invention to one or more parties, can also qualify for small entity status if all the parties who have had rights in the invention transferred to them also qualify for small entity status either as a person, small business concern, or nonprofit organization under this section. (2) Small business concern. A small business concern, as used in paragraph (c) of this section, means any business concern that: (i) Has not assigned, granted, conveyed, or licensed, and is under no obligation under contract or law to assign, grant, convey, or license, any rights in the invention to any person, concern, or organization which would not qualify for small entity status as a person, small business concern, or nonprofit organization; and (ii) Meets the size standards set forth in 13 CFR 121.801 through 121.805 to be eligible for reduced patent fees. Questions related to standards for a small business concern may be directed to: Small Business Administration, Size Standards Staff, 409 Third Street, SW., Washington, DC 20416. (3) Nonprofit organization. A nonprofit organization, as used in paragraph (c) of this section, means any nonprofit organization that: (i) Has not assigned, granted, conveyed, or licensed, and is under no obligation under contract or law to assign, grant, convey, or license, any rights in the invention to any person, concern, or organization which would not qualify as a person, small business concern, or a nonprofit organization; and (ii) Is either: (A) A university or other institution of higher education located in any country; (B) An organization of the type described in section 501(c)(3) of the Internal Revenue Code of 1986 (26 U.S.C. 501(c)(3)) and exempt from taxation under section 501(a) of the Internal Revenue Code (26 U.S.C. 501(a)); (C) Any nonprofit scientific or educational organization qualified under a nonprofit organization statute of a state of this country (35 U.S.C. 201(i)); or (D) Any nonprofit organization located in a foreign country which would qualify as a nonprofit organization under paragraphs (a)(3)(ii)(B) of this section or (a)(3)(ii)(C) of this section if it were located in this country. (4) Federal Government Use License Exceptions. In a patent application filed, prosecuted, and if patented, maintained at no expense to the Government, with the exception of any expense taken to deliver the application and fees to the Office on behalf of the applicant: (i) For persons under paragraph (a)(1) of this section, claiming small entity status is not prohibited by: (A) A use license to the Government resulting from a rights determination under Executive Order 10096 made in accordance with § 501.6 of this title; (B) A use license to the Government resulting from Federal agency action pursuant to 15 U.S.C. 3710d(a) allowing the Federal employee-inventor to obtain or retain title to the invention; or (C) A use license to a Federal agency resulting from retention of rights under 35 U.S.C. 202(d) by an inventor employed by a small business concern or nonprofit organization contractor, provided the license is equivalent to the license under 35 U.S.C. 202(c)(4) the Federal agency would have received had the contractor elected to retain title, and all the conditions applicable under § 401.9 of this title to an employee/inventor are met. (ii) For small business concerns and nonprofit organizations under paragraphs (a)(2) and (3) of this section, a use license to a Federal agency resulting from a funding agreement with that agency pursuant to 35 U.S.C. 202(c)(4) does not preclude claiming small entity status, provided that: (A) The subject invention was made solely by employees of the small business concern or nonprofit organization; or (B) In the case of a Federal employee co-inventor, the Federal agency employing such co-inventor took action pursuant to 35 U.S.C. 202(e)(1) to exclusively license or assign whatever rights currently held or that it may acquire in the subject invention to the small business concern or nonprofit organization, subject to the license under 35 U.S.C. 202(c)(4). (iii) For small business concerns and nonprofit organizations under paragraphs (a)(2) and (3) of this section that have collaborated with a Federal agency laboratory pursuant to a cooperative research and development agreement (CRADA) under 15 U.S.C. 3710a(a)(1), claiming small entity status is not prohibited by a use license to the Government pursuant to: (A) 15 U.S.C. 3710a(b)(2) that results from retaining title to an invention made solely by the employee of the small business concern or nonprofit organization; or (B) 15 U.S.C. 3710a(b)(3)(D), provided the laboratory has waived in whole any right of ownership the Government may have to the subject invention made by the small business concern or nonprofit organization, or has exclusively licensed whatever ownership rights the Government may acquire in the subject invention to the small business concern or nonprofit organization. (iv) Regardless of whether an exception under this paragraph (a)(4) applies, no refund under § 1.28(a) is available for any patent fee paid by the Government. (5) Security Interest. A security interest does not involve an obligation to transfer rights in the invention for the purposes of paragraphs (a)(1) through (a)(3) of this section unless the security interest is defaulted upon. (b) Establishment of small entity status permits payment of reduced fees. (1) A small entity, as defined in paragraph (a) of this section, who has properly asserted entitlement to small entity status pursuant to paragraph (c) of this section will be accorded small entity status by the Office in the particular application or patent in which entitlement to small entity status was asserted. Establishment of small entity status allows the payment of certain reduced patent fees pursuant to 35 U.S.C. 41(h)(1). (2) Submission of an original utility application in compliance with the USPTO patent electronic filing system by an applicant who has properly asserted entitlement to small entity status pursuant to paragraph (c) of this section in that application allows the payment of a reduced filing fee pursuant to 35 U.S.C. 41(h)(3). (c) Assertion of small entity status. Any party (person, small business concern or nonprofit organization) should make a determination, pursuant to paragraph (f) of this section, of entitlement to be accorded small entity status based on the definitions set forth in paragraph (a) of this section, and must, in order to establish small entity status for the purpose of paying small entity fees, actually make an assertion of entitlement to small entity status, in the manner set forth in paragraphs (c)(1) or (c)(3) of this section, in the application or patent in which such small entity fees are to be paid. (1) Assertion by writing. Small entity status may be established by a written assertion of entitlement to small entity status. A written assertion must: (i) Be clearly identifiable; (ii) Be signed (see paragraph (c)(2) of this section); and (iii) Convey the concept of entitlement to small entity status, such as by stating that applicant is a small entity, or that small entity status is entitled to be asserted for the application or patent. While no specific words or wording are required to assert small entity status, the intent to assert small entity status must be clearly indicated in order to comply with the assertion requirement. (2) Parties who can sign the written assertion. The written assertion can be signed by: (i) The applicant (§ 1.42 or § 1.421); (ii) A patent practitioner of record or a practitioner acting in a representative capacity under § 1.34; (iii) The inventor or a joint inventor, if the inventor is the applicant; or (iv) The assignee. (3) Assertion by payment of the small entity basic filing, basic transmittal, basic national fee, international search fee, or individual designation fee in an international design application. The payment, by any party, of the exact amount of one of the small entity basic filing fees set forth in § 1.16(a), (b), (c), (d), or (e), the small entity transmittal fee set forth in § 1.445(a)(1) or § 1.1031(a), the small entity international search fee set forth in § 1.445(a)(2) to a Receiving Office other than the United States Receiving Office in the exact amount established for that Receiving Office pursuant to PCT Rule 16, or the small entity basic national fee set forth in § 1.492(a), will be treated as a written assertion of entitlement to small entity status even if the type of basic filing, basic transmittal, or basic national fee is inadvertently selected in error. The payment, by any party, of the small entity first part of the individual designation fee for the United States to the International Bureau (§ 1.1031) will be treated as a written assertion of entitlement to small entity status. (i) If the Office accords small entity status based on payment of a small entity basic filing or basic national fee under paragraph (c)(3) of this section that is not applicable to that application, any balance of the small entity fee that is applicable to that application will be due along with the appropriate surcharge set forth in § 1.16(f), or § 1.16(g). (ii) The payment of any small entity fee other than those set forth in paragraph (c)(3) of this section (whether in the exact fee amount or not) will not be treated as a written assertion of entitlement to small entity status and will not be sufficient to establish small entity status in an application or a patent. (4) Assertion required in related, continuing, and reissue applications. Status as a small entity must be specifically established by an assertion in each related, continuing and reissue application in which status is appropriate and desired. Status as a small entity in one application or patent does not affect the status of any other application or patent, regardless of the relationship of the applications or patents. The refiling of an application under § 1.53 as a continuation, divisional, or continuation-in-part application (including a continued prosecution application under § 1.53(d)), or the filing of a reissue application, requires a new assertion as to continued entitlement to small entity status for the continuing or reissue application. (d) When small entity fees can be paid. Any fee, other than the small entity basic filing fees and the small entity national fees of paragraph (c)(3) of this section, can be paid in the small entity amount only if it is submitted with, or subsequent to, the submission of a written assertion of entitlement to small entity status, except when refunds are permitted by § 1.28(a). (e) Only one assertion required. (1) An assertion of small entity status need only be filed once in an application or patent. Small entity status, once established, remains in effect until changed pursuant to paragraph (g)(1) of this section. Where an assignment of rights or an obligation to assign rights to other parties who are small entities occurs subsequent to an assertion of small entity status, a second assertion is not required. (2) Once small entity status is withdrawn pursuant to paragraph (g)(2) of this section, a new written assertion is required to again obtain small entity status. (f) Assertion requires a determination of entitlement to pay small entity fees. Prior to submitting an assertion of entitlement to small entity status in an application, including a related, continuing, or reissue application, a determination of such entitlement should be made pursuant to the requirements of paragraph (a) of this section. It should be determined that all parties holding rights in the invention qualify for small entity status. The Office will generally not question any assertion of small entity status that is made in accordance with the requirements of this section, but note paragraph (h) of this section. (g)(1) New determination of entitlement to small entity status is needed when issue and maintenance fees are due. Once status as a small entity has been established in an application or patent, fees as a small entity may thereafter be paid in that application or patent without regard to a change in status until the issue fee is due or any maintenance fee is due. (2) Notification of loss of entitlement to small entity status is required when issue and maintenance fees are due. Notification of a loss of entitlement to small entity status must be filed in the application or patent prior to paying, or at the time of paying, the earliest of the issue fee or any maintenance fee due after the date on which status as a small entity as defined in paragraph (a) of this section is no longer appropriate. The notification that small entity status is no longer appropriate must be signed by a party identified in § 1.33(b). Payment of a fee in other than the small entity amount is not sufficient notification that small entity status is no longer appropriate. (h) Fraud attempted or practiced on the Office. (1) Any attempt to fraudulently establish status as a small entity, or pay fees as a small entity, shall be considered as a fraud practiced or attempted on the Office. (2) Improperly, and with intent to deceive, establishing status as a small entity, or paying fees as a small entity, shall be considered as a fraud practiced or attempted on the Office.

37 C.F.R. § 1.28 Refunds when small entity status is later established; how errors in small entity status are excused.

(a) Refunds based on later establishment of small entity status. A refund pursuant to § 1.26, based on establishment of small entity status, of a portion of fees timely paid in full prior to establishing status as a small entity may only be obtained if an assertion under § 1.27(c) and a request for a refund of the excess amount are filed within three months of the date of the timely payment of the full fee. The three-month time period is not extendable under § 1.136. Status as a small entity is waived for any fee by the failure to establish the status prior to paying, at the time of paying, or within three months of the date of payment of, the full fee. (b) Date of payment. (1) The three-month period for requesting a refund, pursuant to paragraph (a) of this section, starts on the date that a full fee has been paid; (2) The date when a deficiency payment is paid in full determines the amount of deficiency that is due, pursuant to paragraph (c) of this section. (c) How errors in small entity status are excused. If status as a small entity is established in good faith, and fees as a small entity are paid in good faith, in any application or patent, and it is later discovered that such status as a small entity was established in error, or that through error the Office was not notified of a loss of entitlement to small entity status as required by § 1.27(g)(2), the error will be excused upon: compliance with the separate submission and itemization requirements of paragraphs (c)(1) and (c)(2) of this section, and the deficiency payment requirement of paragraph (c)(2) of this section: (1) Separate submission required for each application or patent. Any paper submitted under this paragraph must be limited to the deficiency payment (all fees paid in error), required by paragraph (c)(2) of this section, for one application or one patent. Where more than one application or patent is involved, separate submissions of deficiency payments (e.g., checks) and itemizations are required for each application or patent. See § 1.4(b). (2) Payment of deficiency owed. The deficiency owed, resulting from the previous erroneous payment of small entity fees, must be paid. (i) Calculation of the deficiency owed. The deficiency owed for each previous fee erroneously paid as a small entity is the difference between the current fee amount (for other than a small entity) on the date the deficiency is paid in full and the amount of the previous erroneous (small entity) fee payment. The total deficiency payment owed is the sum of the individual deficiency owed amounts for each fee amount previously erroneously paid as a small entity. Where a fee paid in error as a small entity was subject to a fee decrease between the time the fee was paid in error and the time the deficiency is paid in full, the deficiency owed is equal to the amount (previously) paid in error; (ii) Itemization of the deficiency payment. An itemization of the total deficiency payment is required. The itemization must include the following information: (A) Each particular type of fee that was erroneously paid as a small entity, (e.g., basic statutory filing fee, two-month extension of time fee) along with the current fee amount for a non-small entity; (B) The small entity fee actually paid, and when. This will permit the Office to differentiate, for example, between two one-month extension of time fees erroneously paid as a small entity but on different dates; (C) The deficiency owed amount (for each fee erroneously paid); and (D) The total deficiency payment owed, which is the sum or total of the individual deficiency owed amounts set forth in paragraph (c)(2)(ii)(C) of this section. (3) Failure to comply with requirements. If the requirements of paragraphs (c)(1) and (c)(2) of this section are not complied with, such failure will either: be treated as an authorization for the Office to process the deficiency payment and charge the processing fee set forth in § 1.17(i), or result in a requirement for compliance within a one-month non-extendable time period under § 1.136(a) to avoid the return of the fee deficiency paper, at the option of the Office. (d) Payment of deficiency operates as notification of loss of status. Any deficiency payment (based on a previous erroneous payment of a small entity fee) submitted under paragraph (c) of this section will be treated under § 1.27(g)(2) as a notification of a loss of entitlement to small entity status.

37 C.F.R. § 1.29 Micro entity status.

(a) To establish micro entity status under this paragraph, the applicant must certify that: (1) The applicant qualifies as a small entity as defined in § 1.27 without relying on a government use license exception under § 1.27(a)(4); (2) Neither the applicant nor the inventor nor a joint inventor has been named as the inventor or a joint inventor on more than four previously filed patent applications, other than applications filed in another country, provisional applications under 35 U.S.C. 111(b), or international applications for which the basic national fee under 35 U.S.C. 41(a) was not paid; (3) Neither the applicant nor the inventor nor a joint inventor, in the calendar year preceding the calendar year in which the applicable fee is being paid, had a gross income, as defined in section 61(a) of the Internal Revenue Code of 1986 (26 U.S.C. 61(a)), exceeding three times the median household income for that preceding calendar year, as most recently reported by the Bureau of the Census; and (4) Neither the applicant nor the inventor nor a joint inventor has assigned, granted, or conveyed, nor is under an obligation by contract or law to assign, grant, or convey, a license or other ownership interest in the application concerned to an entity that, in the calendar year preceding the calendar year in which the applicable fee is being paid, had a gross income, as defined in section 61(a) of the Internal Revenue Code of 1986, exceeding three times the median household income for that preceding calendar year, as most recently reported by the Bureau of the Census. (b) An applicant, inventor, or joint inventor is not considered to be named on a previously filed application for purposes of paragraph (a)(2) of this section if the applicant, inventor, or joint inventor has assigned, or is under an obligation by contract or law to assign, all ownership rights in the application as the result of the applicant's, inventor's, or joint inventor's previous employment. (c) If an applicant's, inventor's, joint inventor's, or entity's gross income in the preceding calendar year is not in United States dollars, the average currency exchange rate, as reported by the Internal Revenue Service, during that calendar year shall be used to determine whether the applicant's, inventor's, joint inventor's, or entity's gross income exceeds the threshold specified in paragraph (a)(3) or (4) of this section. (d) To establish micro entity status under this paragraph, the applicant must certify that: (1) The applicant qualifies as a small entity as defined in § 1.27 without relying on a government use license exception under § 1.27(a)(4); (2)(i) The applicant's employer, from which the applicant obtains the majority of the applicant's income, is an institution of higher education as defined in section 101(a) of the Higher Education Act of 1965 (20 U.S.C. 1001(a)); or (ii) The applicant has assigned, granted, conveyed, or is under an obligation by contract or law, to assign, grant, or convey, a license or other ownership interest in the particular application to such an institution of higher education. (e) Micro entity status is established in an application by filing a micro entity certification in writing complying with the requirements of either paragraph (a) or (d) of this section and signed either in compliance with § 1.33(b), in an international application filed in a Receiving Office other than the United States Receiving Office by a person authorized to represent the applicant under § 1.455, or in an international design application by a person authorized to represent the applicant under § 1.1041 before the International Bureau where the micro entity certification is filed with the International Bureau. Status as a micro entity must be specifically established in each related, continuing and reissue application in which status is appropriate and desired. Status as a micro entity in one application or patent does not affect the status of any other application or patent, regardless of the relationship of the applications or patents. The refiling of an application under § 1.53 as a continuation, divisional, or continuation-in-part application (including a continued prosecution application under § 1.53(d)), or the filing of a reissue application, requires a new certification of entitlement to micro entity status for the continuing or reissue application. (f) A fee may be paid in the micro entity amount only if it is submitted with, or subsequent to, the submission of a certification of entitlement to micro entity status. (g) A certification of entitlement to micro entity status need only be filed once in an application or patent. Micro entity status, once established, remains in effect until changed pursuant to paragraph (i) of this section. However, a fee may be paid in the micro entity amount only if status as a micro entity as defined in paragraph (a) or (d) of this section is appropriate on the date the fee is being paid. Where an assignment of rights or an obligation to assign rights to other parties who are micro entities occurs subsequent to the filing of a certification of entitlement to micro entity status, a second certification of entitlement to micro entity status is not required. (h) Prior to submitting a certification of entitlement to micro entity status in an application, including a related, continuing, or reissue application, a determination of such entitlement should be made pursuant to the requirements of this section. It should be determined that each applicant qualifies for micro entity status under paragraph (a) or (d) of this section, and that any other party holding rights in the invention qualifies for small entity status under § 1.27. The Office will generally not question certification of entitlement to micro entity status that is made in accordance with the requirements of this section. (i) Notification of a loss of entitlement to micro entity status must be filed in the application or patent prior to paying, or at the time of paying, any fee after the date on which status as a micro entity as defined in paragraph (a) or (d) of this section is no longer appropriate. The notification that micro entity status is no longer appropriate must be signed by a party identified in § 1.33(b). Payment of a fee in other than the micro entity amount is not sufficient notification that micro entity status is no longer appropriate. A notification that micro entity status is no longer appropriate will not be treated as a notification that small entity status is also no longer appropriate unless it also contains a notification of loss of entitlement to small entity status under § 1.27(f)(2). Once a notification of a loss of entitlement to micro entity status is filed in the application or patent, a new certification of entitlement to micro entity status is required to again obtain micro entity status. (j) Any attempt to fraudulently establish status as a micro entity, or pay fees as a micro entity, shall be considered as a fraud practiced or attempted on the Office. Improperly, and with intent to deceive, establishing status as a micro entity, or paying fees as a micro entity, shall be considered as a fraud practiced or attempted on the Office. (k) If status as a micro entity is established in good faith in an application or patent, and fees as a micro entity are paid in good faith in the application or patent, and it is later discovered that such micro entity status either was established in error, or that the Office was not notified of a loss of entitlement to micro entity status as required by paragraph (i) of this section through error, the error will be excused upon compliance with the separate submission and itemization requirements of paragraph (k)(1) of this section and the deficiency payment requirement of paragraph (k)(2) of this section. (1) Any paper submitted under this paragraph must be limited to the deficiency payment (all fees paid in error) required for a single application or patent. Where more than one application or patent is involved, separate submissions of deficiency payments are required for each application or patent (see § 1.4(b)). The paper must contain an itemization of the total deficiency payment for the single application or patent and include the following information: (i) Each particular type of fee that was erroneously paid as a micro entity, (e.g., basic statutory filing fee, two-month extension of time fee) along with the current fee amount for a small or non-small entity, as applicable; (ii) The micro entity fee actually paid, and the date on which it was paid; (iii) The deficiency owed amount (for each fee erroneously paid); and (iv) The total deficiency payment owed, which is the sum or total of the individual deficiency owed amounts as set forth in paragraph (k)(2) of this section. (2) The deficiency owed, resulting from the previous erroneous payment of micro entity fees, must be paid. The deficiency owed for each previous fee erroneously paid as a micro entity is the difference between the current fee amount for a small entity or non-small entity, as applicable, on the date the deficiency is paid in full and the amount of the previous erroneous micro entity fee payment. The total deficiency payment owed is the sum of the individual deficiency owed amounts for each fee amount previously and erroneously paid as a micro entity. (3) If the requirements of paragraphs (k)(1) and (2) of this section are not complied with, such failure will either be treated at the option of the Office as an authorization for the Office to process the deficiency payment and charge the processing fee set forth in § 1.17(i), or result in a requirement for compliance within a one-month time period that is not extendable under § 1.136(a) to avoid the return of the fee deficiency payment. (4) Any deficiency payment (based on a previous erroneous payment of a micro entity fee) submitted under this paragraph will be treated as a notification of a loss of entitlement to micro entity status under paragraph (i) of this section.

37 C.F.R. § 1.14 Patent applications preserved in confidence.

(a) Confidentiality of patent application information. Patent applications that have not been published under 35 U.S.C. 122(b) are generally preserved in confidence pursuant to 35 U.S.C. 122(a). Information concerning the filing, pendency, or subject matter of an application for patent, including status information, and access to the application, will only be given to the public as set forth in § 1.11 or in this section. (1) Records associated with patent applications (see paragraph (g) of this section for international applications and paragraph (j) of this section for international design applications) may be available in the following situations: (i) Patented applications and statutory invention registrations. The file of an application that has issued as a patent or published as a statutory invention registration is available to the public as set forth in § 1.11(a). A copy of the patent application-as-filed, the file contents of the application, or a specific document in the file of such an application may be provided upon request and payment of the appropriate fee set forth in § 1.19(b). (ii) Published abandoned applications. The file of an abandoned published application is available to the public as set forth in § 1.11(a). A copy of the application-as-filed, the file contents of the published application, or a specific document in the file of the published application may be provided to any person upon request and payment of the appropriate fee set forth in § 1.19(b). (iii) Published pending applications. A copy of the application-as-filed, the file contents of the application, or a specific document in the file of a pending published application may be provided to any person upon request and payment of the appropriate fee set forth in § 1.19(b). If a redacted copy of the application was used for the patent application publication, the copy of the specification, drawings, and papers may be limited to a redacted copy. The Office will not provide access to the paper file of a pending application that has been published, except as provided in paragraph (c) or (i) of this section. (iv) Unpublished abandoned applications (including provisional applications) that are identified or relied upon. The file contents of an unpublished, abandoned application may be made available to the public if the application is identified in a U.S. patent, a statutory invention registration, a U.S. patent application publication, an international publication of an international application under PCT Article 21(2), or a publication of an international registration under Hague Agreement Article 10(3) of an international design application designating the United States. An application is considered to have been identified in a document, such as a patent, when the application number or serial number and filing date, first named inventor, title, and filing date or other application specific information are provided in the text of the patent, but not when the same identification is made in a paper in the file contents of the patent and is not included in the printed patent. Also, the file contents may be made available to the public, upon a written request, if benefit of the abandoned application is claimed under 35 U.S.C. 119(e), 120, 121, 365(c), or 386(c) in an application that has issued as a U.S. patent, or has published as a statutory invention registration, a U.S. patent application publication, an international publication of an international application under PCT Article 21(2), or a publication of an international registration under Hague Agreement Article 10(3). A copy of the application-as-filed, the file contents of the application, or a specific document in the file of the application may be provided to any person upon written request and payment of the appropriate fee (§ 1.19(b)). (v) Unpublished pending applications (including provisional applications) whose benefit is claimed. A copy of the file contents of an unpublished pending application may be provided to any person, upon written request and payment of the appropriate fee (§ 1.19(b)), if the benefit of the application is claimed under 35 U.S.C. 119(e), 120, 121, 365(c), or 386(c) in an application that has issued as a U.S. patent, or in an application that has published as a statutory invention registration, a U.S. patent application publication, an international publication of an international application under PCT Article 21(2), or a publication of an international registration under Hague Agreement Article 10(3). A copy of the application-as-filed or a specific document in the file of the pending application may also be provided to any person upon written request and payment of the appropriate fee (§ 1.19(b)). The Office will not provide access to the paper file of a pending application, except as provided in paragraph (c) or (i) of this section. (vi) Unpublished pending applications (including provisional applications) that are incorporated by reference or otherwise identified. A copy of the application as originally filed of an unpublished pending application may be provided to any person, upon written request and payment of the appropriate fee (§ 1.19(b)), if the application is incorporated by reference or otherwise identified in a U.S. patent, a statutory invention registration, a U.S. patent application publication, an international publication of an international application under PCT Article 21(2), or a publication of an international registration under Hague Agreement Article 10(3) of an international design application designating the United States. The Office will not provide access to the paper file of a pending application, except as provided in paragraph (c) or (i) of this section. (vii) When a petition for access or a power to inspect is required. Applications that were not published or patented, that are not the subject of a benefit claim under 35 U.S.C. 119(e), 120, 121, 365(c), or 386(c) in an application that has issued as a U.S. patent, an application that has published as a statutory invention registration, a U.S. patent application publication, an international publication of an international application under PCT Article 21(2), or a publication of an international registration under Hague Agreement Article 10(3), or are not identified in a U.S. patent, a statutory invention registration, a U.S. patent application publication, an international publication of an international application under PCT Article 21(2), or a publication of an international registration under Hague Agreement Article 10(3) of an international design application designating the United States, are not available to the public. If an application is identified in the file contents of another application, but not the published patent application or patent itself, a granted petition for access (see paragraph (i)) or a power to inspect (see paragraph (c) of this section) is necessary to obtain the application, or a copy of the application. (2) Information concerning a patent application may be communicated to the public if the patent application is identified in a published patent document or in an application as set forth in paragraphs (a)(1)(i) through (a)(1)(vi) of this section. The information that may be communicated to the public (i.e., status information) includes: (i) Whether the application is pending, abandoned, or patented; (ii) Whether the application has been published under 35 U.S.C. 122(b); (iii) The application “numerical identifier” which may be: (A) The eight-digit application number (the two-digit series code plus the six-digit serial number); or (B) The six-digit serial number plus any one of the filing date of the national application, the international filing date, or date of entry into the national stage; and (iv) Whether another application claims the benefit of the application (i.e., whether there are any applications that claim the benefit of the filing date under 35 U.S.C. 119(e), 120, 121, 365, or 386 of the application), and if there are any such applications, the numerical identifier of the application, the specified relationship between the applications (e.g., continuation), whether the application is pending, abandoned or patented, and whether the application has been published under 35 U.S.C. 122(b). (b) Electronic access to an application. Where a copy of the application file or access to the application may be made available pursuant to this section, the Office may at its discretion provide access to only an electronic copy of the specification, drawings, and file contents of the application. (c) Power to inspect a pending or abandoned application. Access to an application may be provided to any person if the application file is available, and the application contains written authority (e.g., a power to inspect) granting access to such person. The written authority must be signed by: (1) The applicant; (2) A patent practitioner of record; (3) The assignee or an assignee of an undivided part interest; (4) The inventor or a joint inventor; or (5) A registered attorney or agent named in the papers accompanying the application papers filed under § 1.53 or the national stage documents filed under § 1.495, if a power of attorney has not been appointed under § 1.32. (d) Applications reported to Department of Energy. Applications for patents which appear to disclose, purport to disclose or do disclose inventions or discoveries relating to atomic energy are reported to the Department of Energy, which Department will be given access to the applications. Such reporting does not constitute a determination that the subject matter of each application so reported is in fact useful or is an invention or discovery, or that such application in fact discloses subject matter in categories specified by 42 U.S.C. 2181(c) and (d). (e) Decisions by the Director. Any decision by the Director that would not otherwise be open to public inspection may be published or made available for public inspection if: (1) The Director believes the decision involves an interpretation of patent laws or regulations that would be of precedential value; and (2) The applicant is given notice and an opportunity to object in writing within two months on the ground that the decision discloses a trade secret or other confidential information. Any objection must identify the deletions in the text of the decision considered necessary to protect the information, or explain why the entire decision must be withheld from the public to protect such information. An applicant or party will be given time, not less than twenty days, to request reconsideration and seek court review before any portions of a decision are made public under this paragraph over his or her objection. (f) Notice to inventor of the filing of an application. The Office may publish notice in the Official Gazette as to the filing of an application on behalf of an inventor by a person who otherwise shows sufficient proprietary interest in the matter. (g) International applications. (1) Copies of international application files for international applications which designate the U.S. and which have been published in accordance with PCT Article 21(2), or copies of a document in such application files, will be furnished in accordance with PCT Articles 30 and 38 and PCT Rules 94.2 and 94.3, upon written request including a showing that the publication of the application has occurred and that the U.S. was designated, and upon payment of the appropriate fee (see § 1.19(b)), if: (i) With respect to the Home Copy (the copy of the international application kept by the Office in its capacity as the Receiving Office, see PCT Article 12(1)), the international application was filed with the U.S. Receiving Office; (ii) With respect to the Search Copy (the copy of an international application kept by the Office in its capacity as the International Searching Authority, see PCT Article 12(1)), the U.S. acted as the International Searching Authority, except for the written opinion of the International Searching Authority which shall not be available until the expiration of thirty months from the priority date; or (iii) With respect to the Examination Copy (the copy of an international application kept by the Office in its capacity as the International Preliminary Examining Authority), the United States acted as the International Preliminary Examining Authority, an International Preliminary Examination Report has issued, and the United States was elected. (2) A copy of an English language translation of a publication of an international application which has been filed in the United States Patent and Trademark Office pursuant to 35 U.S.C. 154(d)(4) will be furnished upon written request including a showing that the publication of the application in accordance with PCT Article 21(2) has occurred and that the U.S. was designated, and upon payment of the appropriate fee (§ 1.19(b)(4)).
