Arizona's Patent and Trademark Resource Center (PTRC): Patents

The State of Arizona Research Library is Arizona's designated Patent and Trademark Resource Center (PTRC). We invite you to explore the research supports available to you as you pursue intellectual property protection.

What is a PTRC?

The State of Arizona Research Library is a designated Patent and Trademark Resource Center by the United States Patent and Trademark Office (USPTO). PTRCs are a nationwide network of public, state and academic libraries that are designated by the USPTO to disseminate patent and trademark information and to support the diverse intellectual property needs of the public.

The State of Arizona Research Library is the only PTRC in Arizona, and one of about eighty in the United States. View PTRC locations by state on the USPTO's site.
