Public Inquiries About Applications and Registrations

1801 USPTO Personnel May Not Express Opinion on Validity of Registered Trademark

A certificate of registration of a mark on the Principal Register is prima facie evidence of the validity of the registration. 15 U.S.C. §1057(b) . Public policy demands that every employee of the United States Patent and Trademark Office (USPTO) refuse to express to any person any opinion as to the validity of any registered mark, except to the extent necessary to carry out inter partes proceedings at the Trademark Trial and Appeal Board (Board) in cancellation and similar proceedings authorized by law.

Members of the Trademark Examining Operation are cautioned to be especially wary of inquiries from persons outside the USPTO, including employees of another government agency, the answer to which might indicate that a particular registration should not have been published or issued.

An employee of the USPTO, particularly a trademark examining attorney who examined an application, should not discuss or answer inquiries from any person outside the USPTO as to whether a certain registration or particular evidence was considered during the examination of the application, or whether a mark would have been published or registered if the registration or other evidence had been considered during the examination. Likewise, employees should not answer any inquiry concerning any entry in a registration file, including the extent of the field of search. The record of the file of a registration or inter partes proceeding before the Board must speak for itself.

Employees must not discuss these matters with members of the public. Qualified U.S. attorneys should not make improper inquiries of members of the Trademark Examining Operation.

See TMEP §1806 regarding contacts with third parties about ex parte matters.

Subpart E--Tort Claims

37C.F.R.Procedure for filing claims.

Administrative claims against the Office filed pursuant to the administrative claims provision of the Federal Tort Claims Act (28 U.S.C. 2672) and the corresponding Department of Justice regulations (28 CFR Part 14) shall be filed with the General Counsel as indicated in §104.2.

37C.F.R.Finality of settlement or denial of claims.

Only a decision of the Director or the General Counsel regarding settlement or denial of any claim under this subpart may be considered final for the purpose of judicial review.

It is the policy of the USPTO that its employees, including trademark examining attorneys, will not appear as witnesses or give testimony in legal proceedings, except under the conditions specified in 37C.F.R. Part 104. Any employee who testifies contrary to this policy will be dismissed or removed.

Whenever an employee of the USPTO, including a trademark examining attorney, is asked to testify or receives a subpoena, the employee shall immediately notify the Office of the General Counsel. Inquiries requesting testimony should also be referred immediately to the Office of the General Counsel.

Trademark examining attorneys and other USPTO employees who perform or assist in the performance of quasi-judicial functions, are forbidden to testify as experts or to express opinions as to the validity of any registration.

Any individual desiring the testimony of an employee of the USPTO, including the testimony of a trademark examining attorney or other quasi-judicial employee, must comply with the provisions of 37C.F.R. Part 104.

A request for testimony of an employee of the USPTO should be made to the Office of the General Counsel at least ten working days prior to the date of the expected testimony.

If an employee is authorized to testify, the employee will be limited to testifying about facts within the employee’s personal knowledge. Employees are prohibited from giving expert or opinion testimony. Fischer & Porter Co. v. Corning Glass Works , 61 F.R.D. 321, 181 USPQ 329 (E.D. Pa. 1974). Likewise, employees are prohibited from answering hypothetical or speculative questions. Shaffer Tool Works v. Joy Mfg. Co., 167 USPQ 170 (S.D. Tex. 1970) (deposition of examiner should be limited to matters of fact and must not go into hypothetical or speculative areas or the bases, reasons, mental processes, analyses, or conclusions of the examiner); In re Mayewsky, 162 USPQ 86, 89 (E.D. Va. 1969) (deposition of an examiner must be restricted to relevant matters of fact and must avoid any hypothetical or speculative questions or conclusions). Employees will not be permitted to give testimony with respect to subject matter that is privileged. Several court decisions limit testimony with respect to quasi-judicial functions performed by employees. U.S. v. Morgan, 313 U.S. 409, 422 (1941) (improper to inquire into mental processes of quasi-judicial officer or to examine the manner and extent to which the officer considered an administrative record); W. Elec. Co. v. Piezo Tech., Inc., 860 F.2d 428, 8 USPQ2d 1853 (Fed. Cir. 1988) (patent examiner may not be compelled to answer questions that probe the examiner’s technical knowledge of the subject matter of a patent); In re Nilssen, 851 F.2d 1401, 7USPQ2d 1500 (Fed. Cir. 1988) (technical or scientific qualifications of examiners-in-chief are not legally relevant in appeal under 35U.S.C. §134 since board members need not be skilled in the art to render obviousness decision); McCulloch Gas Processing Co. v. Dep't of Energy , 650 F.2d 1216, 1229 (Temp. Emer. Ct. App. 1981) (discovery of degree of expertise of individuals performing governmental functions not permitted); Lange v. Comm'r, 352 F. Supp. 116, 176 USPQ 162 (D.D.C. 1972) (technical qualifications of examiners-in-chief not relevant in Section 145 action).

In view of the discussion above, if an employee is authorized to testify in connection with the employee’s involvement or assistance in a quasi-judicial proceeding that took place before the USPTO, the employee will not be permitted to give testimony in response to questions that seek:

  • (1) Information about that employee’s:
  • (A) Background.
  • (B) Expertise.
  • (C) Qualifications to examine or otherwise consider a particular patent or trademark application.
  • (D) Usual practice or whether the employee followed a procedure set out in any USPTO manual of practice (including the MPEP or TMEP) in a particular case.
  • (E) Consultation with another USPTO employee.
  • (F) Understanding of:
  • (i) A patented invention, an invention sought to be patented, or patent application, patent, reexamination or interference file.
  • (ii) Prior art.
  • (iii) Registered subject matter, subject matter sought to be registered, or a trademark application, registration, opposition, cancellation, interference or concurrent use file.
  • (iv) Any USPTO manual of practice.
  • (v) USPTO regulations.
  • (vi) Patent, trademark, or other law.
  • (vii) The responsibilities of another USPTO employee.
  • (G) Reliance on particular facts or arguments.
  • (2) To inquire into the manner in and extent to which the employee considered or studied material in performing the quasi-judicial function.
  • (3) To inquire into the bases, reasons, mental processes, analyses, or conclusions of that USPTO employee in performing the quasi-judicial function.

Any request for testimony addressed or delivered to the Office of the General Counsel must comply with 37C.F.R. §104.22(c). All requests must be in writing. The need for a subpoena may be obviated where the request complies with 37C.F.R. §104.22(c) only if the party requesting the testimony meets the following conditions:

  • (1) The party requesting the testimony identifies the civil action or other legal proceeding for which the testimony is being taken. The identification shall include:
  • (A) the style of the case,
  • (B) the civil action number,
  • (C) the district in which the civil action is pending,
  • (D) the judge assigned to the case, and
  • (E) the name, address, and telephone number of counsel for all parties in the civil action.
  • (2) The party agrees not to ask questions seeking information that is precluded by 37C.F.R. §104.23.
  • (3) The party must comply with applicable provisions of the Federal Rules of Civil Procedure, including Rule 30, and give ten working days notice to the Office of the General Counsel prior to the date a deposition is desired. Fifteen working days notice is required for any deposition that is desired to be taken between November 15 and January 15.
  • (4) The party agrees to notice the deposition at a place convenient to the USPTO. The Conference Room in the Office of the General Counsel is deemed to be a place convenient to the USPTO.
  • (5) The party agrees to supply a copy of the transcript of the deposition to the USPTO for its records.

Absent a written agreement meeting the conditions specified in paragraphs (1)through (5), a party must comply with the specific terms of 37C.F.R. §104.22(c), and the USPTO will not permit a deposition without issuance of a subpoena.

See Service of Process & Testimony of Employees of the Patent & Trademark Office & Production of Documents in Legal Proceedings , 1099 TMOG 44 (Feb. 28, 1989).

1802 Congressional and Other Official Inquiries

Correspondence and inquiries from the White House, members of the U.S. Congress, embassies, and heads of U.S. executive departments and agencies normally are cleared by the USPTO’s Office of Policy and International Affairs and/or the Office of Governmental Affairs.

Inquiries referred to in this section such as correspondence from foreign embassies, the Office of the U.S. Trade Representative, and the U.S. Department of State must immediately be transmitted to the USPTO's Office of the Administrator for Policy and International Affairs, and a staff member of that office must be notified by phone that such correspondence has been received at 571-272-9300. Inquiries referred to in this section, such as correspondence from the U.S. Congress or the White House, must immediately be transmitted to the USPTO's Director of the Office of Governmental Affairs, and a staff member of that office must be notified by phone that such correspondence has been received at 571-272-7300.

This procedure is used so that there will be uniformity in the handling of contacts from the indicated sources, and also so that compliance with directives of the U.S. Department of Commerce is attained.

1803 Freedom of Information Act Requests

Freedom of Information Act (FOIA) requests may be submitted by mail, email, or hand delivered to the attention of the USPTO FOIA Officer at one of the following addresses:

By mail:


U.S. Patent and Trademark Office

P.O. Box 1450



By email:

By hand:


U.S. Patent and Trademark Office

Madison East Building

600 Dulany Street



The request must be made in writing. No telephone requests will be accepted.

An email request must state that the request is made pursuant to FOIA and describe the records sought. Failure to do so may result in an email not being properly identified as a FOIA request. Email submissions not considered FOIA requests may be disregarded. The email must also include the requestor’s mailing address as not all USPTO records are reasonably available in a format suitable for emailing. Failure to provide a mailing address could result in a delay in processing the request.

Copies of the USPTO's final agency decisions and most frequently requested FOIA documents are available on the USPTO website at .

1804 Inquiries from Members of the Press

Inquiries from members of the press should be directed to the USPTO's Office of the Chief Communications Officer at (571) 272-8400.

1805 General Inquiries from the Public

For general questions about the procedures for obtaining and maintaining a registration, callers may telephone the Trademark Assistance Center (TAC) at (571)272-9250 or (800)786-9199, or email TAC at . See TMEP §108.02 for more information regarding TAC and its operating hours.

However, USPTO employees may not:

  • conduct trademark searches for the public ( see TMEP §104 );
  • comment on the validity of registered marks ( see TMEP §1801 );
  • answer questions as to whether a particular mark or type of mark is eligible for registration;
  • offer legal advice or opinions about a mark’s eligibility for registration, common-law trademark rights, state registrations, or trademark infringement claims; or
  • aid in the selection of a private trademark attorney or search firm ( 37 C.F.R §2.11(a) ).

For a legal opinion about a trademark matter, a party must consult a private U.S.-licensed trademark attorney. The USPTO cannot aid in the selection of an attorney. 37C.F.R. §2.11(a) . To find the names of private attorneys who are licensed to practice law in the U.S. and handle trademark matters, consult telephone listings or the internet, or contact the attorney referral service of a U.S. state or local bar association (see the American Bar Association’s Consumers’ Guide to Legal Help). Information about selecting a U.S.-licensed trademark attorney is also available on the USPTO website.

See TMEP §104 regarding trademark search systems.

See TMEP §1806 regarding contacts with third parties about ex parte matters.

1806 Contacts with Third Parties Regarding Ex Parte Matters

An examining attorney or other USPTO employee may not discuss the merits of any particular application or registration with a third party. If a third party attempts to contact an examining attorney about an ex parte matter, either orally or in writing, the examining attorney should refer the third party to the Office of the Deputy Commissioner for Trademark Examination Policy. See TBMP §1715 et seq. regarding letters of protest.
