In response to public feedback regarding the retirement of the legacy search systems, a new simplified interface of Patent Public Search named Basic Search is now available. Basic Search is recommended for users new to Patent Public Search, or for users who only need to perform a quick look up.
PatFT, AppFT, PubEAST and PubWEST were retired on September 30. Preexisting links to U.S. patents and pre-grant publications are no longer available. You will need to create new links for saved documents. Read through this step-by-step guide on how to set up a web link to access a saved document, as well as set up saved search queries. For questions regarding Patent Public Search, please contact the Public Search Facility at email@example.com.
