Patent and Trademark Resource Center (PTRC) libraries offer PubWEST and PubEAST products for use in patent research. These products are not required for searching patent records but are available for those interested in using them. Because the products are available only in PTRC locations, we recommend that a new searcher first become acquainted with the tools freely available through the Internet.
Those wishing to advance to the “expert” level of manipulating records (and who live fairly close) have the option of using these products. *Please call to confirm before coming to the library.
PubWEST - Public version of the Web-based Examiner Search Tool
PubEAST - Public Examiner’s Automated Search Tool
PubEAST - provides seamless access to multiple text data sources including the Pre-Grant Publications (US-PGPUB), United States Patents (USPAT), United States Optical Character Recognition (USOCR), European Patent Office (EPO) Abstracts, Japanese Patent Office (JPO) Abstracts, and Foreign Patent Retrieval System (FPRS) databases, as well as image data sources for full and clipped images.
PubEAST accesses the same databases as PubWEST but has a different, less intuitive search interface. Nevertheless, it is considered by some experts to be superior to PubWest.
Access to PubWEST and PubEAST is provided on the entry level of the Perry-Castañeda Library (PCL). Ask for assistance at the Research Help & Check Out Desk.
