Copies of International Application Files Upon Request
Note:
The U.S. can provide copies of the Home and Search Copies upon request when it acts as both the receiving Office and the International Searching Authority.

37 CFR 1.14(g)(1) sets forth those conditions upon which copies of international application files may be provided to the public. 37 CFR 1.14(g)(1)(i) and (ii) address the situation where the U.S. acted as the receiving Office and the International Searching Authority, respectively. Under these provisions, copies of the Home and Search Copies of the international file will be provided upon request. However, the written opinion established by the International Searching Authority will not be available until the expiration of 30 months from the priority date. 37 CFR 1.14(g)(1)(iii) addresses the situation in which the U.S. acted as the International Preliminary Examining Authority (IPEA), the U.S. was elected, and the international preliminary examination report (IPER) has issued. PCT Rule 94.2 provides that after issuance of the IPER, the IPEA shall provide copies of any documents in the examination file to the elected Offices upon request. PCT Rule 94.3 permits the elected Offices to provide access to any documents in its files after international publication has occurred. Therefore, the USPTO acting in its capacity as an elected Office, will provide a copy of the examination file in an international application to a third party upon submission of a request complying with the requirements of 37 CFR 1.14(g)(1)(iii). Requests for copies of an international application file under 37 CFR 1.14(g)(1) must be in the form of a written request sent to the International Patent Legal Administration and must include a showing that the international application has been published and that the U.S. was designated. Such a showing should preferably be in the form of the submission of a copy of the front page of the published international application. Additionally, requests for copies of international application files must also be accompanied by the appropriate fee (37 CFR 1.19(b)).
