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.
