The Wyoming Patent and Trademark Resource Center (PTRC) is a library designated by the U.S. Patent and Trademark Office (USPTO) to disseminate patent and trademark information and support the diverse intellectual property needs of the public. We offer patent and trademark search training to the public. Individual or group training can be scheduled by contacting the PTRC.
As the only PTRC in Wyoming, the Library provides free access to patent and trademark resources in various formats. We offer a designated workstation that provides access to the USPTO Web-based Search Systems, PubEast and PubWest databases. Public versions of the online search tool used by USPTO's patent examiners for more advanced searching.
The collection includes patents issued from 1790 to present; patent applications published since March 15, 2001; pending and registered trademarks from 1871; and USPTO documents. The collection also includes circulating books, magazines, and videos/DVDs to assist with the patenting and trademarking process, to learn about individual inventors and inventions, or the history of technological innovation.
