8 Improvement of Foundation for Prior Art Searches Prior art searches are one of the important pillars for maintaining and improving examination quality, and a constant improvement of the foundation for prior art searches for both patent documents and non-patent literature is therefore crucial. (i) Initiatives Related to Machine Translation Texts • On the retrieval system for patents and utility models used by examiners, the JPO continues to accumulate full text Japanese machine translations of US, EP, and the World Intellectual Property Organization (WIPO) patent documents in English, as well as CN and KR patent documents, in order to retrieve and screen documents in Japanese. (ii) Initiatives Related to the Development of Patent Classifications and Other Search Indices • The JPO attended the IPC Union - Committee of Experts (56th session) and contributed to determining the procedures for revising the International Patent Classification (IPC), IPC revision projects, the Guide to the IPC, etc. (February 2025, hybrid). • As part of improving the foundation for prior art searches, the JPO discussed revising the IPC for approx. 100 technical areas, with aims such as introducing superior classification entries among the File Index (FI) *12 and F-term *13 to the IPC (28th and 29th sessions of the IP5 Working Group 1-Working Group on Classification [March 2025, Seoul and online, and September 2025, online], 53rd and 54th sessions of the IPC Union - IPC Revision Working Group [May 2025, WIPO and online, and October 2025, WIPO and online]). • Under the principle that FI must be compliant with the latest IPC, in FY2025, the JPO amended the FI scheme for approx. 730 main groups and conducted F-term maintenance for 23 themes in order to search efficiently for Japanese and foreign patent documents. • AI is used to automatically assign FI and F-term to foreign patent documents. Both Japanese and foreign patent documents may be searched at once using common patent classifications
