PTRC

The Denver Public Library is a designated Patent & Trademark Resource Center (PTRC). The Patent and Trademark Resource Center is located in the Reference Services Department, Level 3 of the Central Library. As the only PTRC in Colorado, the Library provides free access to patent and trademark resources in various formats, and reference librarians provide assistance and instruction on how to perform a preliminary patent and trademark search.

We offer a designated workstation that provides access to the USPTO Web-based Search Systems and PubWEST database, the public version of the online search tool used by USPTO’s patent examiners for more advanced searching.

To find out more about the library’s patent and trademark collection, please call 720-865-1363. To schedule a one-on-one appointment with a librarian complete the Patent and Trademark Appointment form.

Self-service photocopying or printing of patent documents is available at $.10 per page.

PTRCs are neither required nor encouraged to conduct patent and trademark searches for their patrons as that activity may be interpreted as rendering a judgment or opinion. PTRCs are required to instruct patrons in the use of the search tools available at the PTRCs for patrons conducting their own patent and trademark searches. Please contact a registered patent attorney or agent for a complete patent search and for legal advice.
