37 CFR 1.251 sets forth a procedure for the reconstruction of the file of a patent application, patent, or any other patent-related proceeding that cannot be located after a reasonable search. The phrase “an application” in 37 CFR 1.251 applies to any type of application (national or international), and regardless of the status (pending or abandoned) of the application.

If applicant or patentee does not possess any record of the correspondence between the Office and the applicant or patentee for such application, patent, or other proceeding, the applicant or patentee is to reply with a statement to that effect (37 CFR 1.251(a)(3)).

According to 37 CFR 1.251(a), if the applicant or patentee possesses all or just some of the correspondence between the Office and the applicant or patentee for such application, patent, or other proceeding, the applicant or patentee is to reply by providing a copy of (or producing) his or her record of all of the correspondence between the Office and the applicant or patentee for such application, patent, or other proceeding (37 CFR 1.251(a)(1) or (a)(2)). If applicant or patentee does not possess any record of the correspondence between the Office and the applicant or patentee for such application, patent, or other proceeding, the applicant or patentee is to reply with a statement to that effect (37 CFR 1.251(a)(3)).

If an applicant or patentee decides to produce his or her record of the correspondence between the Office and the applicant or patentee for the application, patent, or other proceeding for copying by the Office under 37 CFR 1.251(a)(2) (rather than provide a copy under 37 CFR 1.251(a)(1)), the record should be brought to the Customer Service Center in the Office of Patent Application Processing (OPAP).

37 CFR 1.251 generally applies only to situations in which the file of an application or patent (not just certain documents) is unlocatable. When a document is missing from an application, Office practice is to call the applicant’s representative and request submission (generally by facsimile) of a copy of the missing document. While the Office will generally treat missing documents in this relatively informal manner (rather than issuing a notice under 37 CFR 1.251), the Office may issue a notice under 37 CFR 1.251 to obtain a copy of a missing document if the Office’s informal attempts to obtain a copy of the document are unsuccessful. The notice under 37 CFR 1.251 will include a printout of the contents entries from the Office’s electronic record system.

Any appendix or information disclosure statement submitted with an application is not contained in the Office’s database. Therefore, the applicant or patentee must also provide a copy of any appendix or information disclosure statement (except in the limited circumstance discussed below) submitted with the application. Since the Office can obtain copies of U.S. patent documents (U.S. patent application publications and patents) from its internal databases, the Office is not requiring applicants or patentees to provide copies of U.S. patent application publications and patents that are among the applicant’s or patentee’s record of the correspondence between the Office and the applicant or patentee for the application, patent, or other proceeding.

37 CFR 1.251(b) provides that with regard to a pending application, the failure to provide a reply to such a notice within the time period set in the notice will result in abandonment of the application. While abandonment (or expiration) of a patent is not an issue if a patentee fails to timely comply with a notice under 37 CFR 1.251, in such a situation the only certified copy of the patent file that the Office will be able to produce will be a copy of the patent and a copy of the application-as-filed (which may have an adverse impact during attempts to enforce the patent). In addition, if the patent is involved in a proceeding before the Office, the Office may take action under 37 CFR 41.128 or 37 CFR 11.18.

The Office will set a time period of three months for reply in a notice under 37 CFR 1.251 in an application. The time period will be extendable under 37 CFR 1.136(a) (unless the notice indicates otherwise) by three months up to a maximum period for reply of six months in an application. See 35 U.S.C. 133. If, however, an applicant fails to reply to a notice under 37 CFR 1.251 within three months of its mailing date, any patent term adjustment under 35 U.S.C. 154(b) will be reduced by a period equal to the number of days (if any) beginning on the day after the date that is three months after the mailing date of the notice under 37 CFR 1.251 and ending on the date the reply to the notice under 37 CFR 1.251 was filed. See 35 U.S.C. 154(b)(2)(C)(ii) and 37 CFR 1.704(b). The Office will set a time period of six months for reply in a notice under 37 CFR 1.251 in a patent. The time period will not be extendable under 37 CFR 1.136(a) in a patent because 35 U.S.C. 41(a)(8) only authorizes the Office to charge fees for extensions of time in proceedings involving an application.
