PubWEST Search Patents and Trademarks

What is PubWEST?

WEST stands for Web-based Examiner’s Search Tool, an internal U.S. Patent and Trademark Office database for use by USPTO patent examiners.
PubWEST is the public version of WEST offered only in the Public Search Facility and Patent and Trademark Depository Libraries, including the Denver Public Library.

Why should I use PubWEST?

This is the search tool used by USPTO patent examiners and professional patent searchers, so you will be searching patents using the same interface as the professionals.
Precision search tools allow for more focused searches, which means fewer patents to wade through.
