Patent and Trademark Resource Centers (PTRCs) are a nationwide network of public, state, and academic libraries that disseminate patent and trademark information and support the diverse intellectual property needs of the public. The PTRCs have trained specialists who may answer specific questions regarding the trademark process, but they do not provide legal advice. More information on PTRCs, including a list of the PTRC(s) in your state, is available at the PTRC section of our website.
