301.01 Accessibility of Assignment Records
37 CFR 1.12 Assignment records open to public inspection.
(a)
(1) Separate assignment records are maintained in the United States Patent and Trademark Office for patents and trademarks. The assignment records, relating to original or reissue patents, including digests and indexes (for assignments recorded on or after May 1, 1957), published patent applications, and assignment records relating to pending or abandoned trademark applications and to trademark registrations (for assignments recorded on or after January 1, 1955), are open to public inspection at the United States Patent and Trademark Office, and copies of those assignment records may be obtained upon request and payment of the fee set forth in § 1.19 and § 2.6 of this chapter.
(2) All records of assignments of patents recorded before May 1, 1957, and all records of trademark assignments recorded before January 1, 1955, are maintained by the National Archives and Records Administration (NARA). The records are open to public inspection. Certified and uncertified copies of those assignment records are provided by NARA upon request and payment of the fees required by NARA.
(b) Assignment records, digests, and indexes relating to any pending or abandoned patent application which has not been published under 35 U.S.C. 122(b) are not available to the public. Copies of any such assignment records and related information shall be obtainable only upon written authority of the applicant or applicant's assignee or attorney or agent or upon a showing that the person seeking such information is a bona fide prospective or actual purchaser, mortgagee, or licensee of such application, unless it shall be necessary to the proper conduct of business before the Office or as provided in this part.
(c) Any request by a member of the public seeking copies of any assignment records of any pending or abandoned patent application preserved in confidence under § 1.14, or any information with respect thereto, must:
(1) Be in the form of a petition including the fee set forth in § 1.17 (h); or
(2) Include written authority granting access to the member of the public to the particular assignment records from the applicant or applicant's assignee or attorney or agent of record.
(d) An order for a copy of an assignment or other document should identify the reel and frame number where the assignment or document is recorded. If a document is identified without specifying its correct reel and frame, an extra charge as set forth in § 1.21(j) will be made for the time consumed in making a search for such assignment.
Assignment documents relating to patents, published patent applications, registrations of trademarks, and applications for registration of trademarks are open to public inspection.
The Office will not open only certain parts of an assignment document to public inspection. If such a document contains two or more items, any one of which, if alone, would be open to such inspection, then the entire document will be open. Thus, if a document covers either a trademark or a patent in addition to one or more patent applications, it will be available to the public ab initio; and if it covers a number of patent applications, it will be so available as soon as any one of them is published or patented. Documents relating only to one or more pending applications for patent which have not been published under 35 U.S.C. 122(b) will not be open to public inspection.
Copies of assignment records relating to pending or abandoned patent applications not published under 35 U.S.C. 122(b) and information related thereto are obtainable upon a showing of written authority from the applicant or applicant's assignee or from the attorney or agent of either, or upon a showing that the person seeking such information is a bona fide prospective or actual purchaser, mortgagee, or licensee of such application.
If the application on which a patent was granted is a division or continuation of an earlier application, the assignment records of that earlier application will be open to public inspection; similar situations involving continuation-in-part applications will be considered on their individual merits upon petition to the Office of Petitions.
Assignment records relating to reissue applications are open to public inspection.
Requests for abstracts of title for assignments of patents recorded after May 1, 1957, are provided by the Certification Division upon request and payment of fee required in 37 CFR 1.19. Requests for copies of pre-1957 records for patents should be directed to the National Archives and Records Administration (NARA). Since these records are maintained by NARA, it is more expeditious to request copies directly from NARA, rather than from the Office, which would then have to route the requests to NARA. Payment of the fees required by NARA should accompany all requests for copies.
All assignment records from 1837 to April 30, 1957 for patents are now maintained and are open for public inspection in the National Archives Research Room located at the Washington National Records Center Building, 4205 Suitland Road, Suitland, Maryland 20746. Assignment documents recorded before 1837 are maintained at the National Archives and Records Administration, 841 South Pickett Street, Alexandria, Virginia 22304.
