Patent Trademark Resource Center

Patents and Trademarks



Supported by a US Patent and Trademark Office (USPTO) program and expert staff, PTRCs disseminate patent and trademark information and support the public's diverse intellectual property needs.

From the Desk of Emeritus UNH Law Library Director Judith Gire:

On January 3, 2012 UNH Law Library received notification from David J. Kappos, Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office, that it had been officially designated as a Patent and Trademark Resource Center (PTRC).  Our library is now part of a nationwide network of public, state and academic libraries designated as PTRC's and authorized by 35 U.S.C. sec. 12 to disseminate patent and trademark information and support diverse intellectual property needs of the public. 

The PTRC Program (formerly known as the Patent and Trademark Depository Library Program or PTDL) has been in existence since 1871 to provide public access to patents. Our Intellectual Property Librarian Professor Jon Cavicchi will serve as our "designated expert."


The UNH Law Library offers the following PTRC services:

  • Access to the open web and private PubWest database for patent searching.
  • Resources for historical patent research.
  • Patent searching guides and other reference materials on intellectual property.
  • USPTO-trained staff to answer patent and trademark questions.
  • Classes and events related to intellectual property.
  • Reference Assistance and Referrals by appointment
  • Patent Classification Research Orientation by appointment
  • Supplemental Reference Materials by appointment
How to Use the UNH Law PTRC Services

Our services are both phyisical and virtual. Most of the PTRC resources are available on the open web.

You can visit our Library and use one of the PTRC Work Stations Monday - Friday 8am to 4pm. Proceed to the Library Circulation Desk. When you arrive, ask the Desk Assistant to point you to the Login Book. After you log in, you will be escorted to the PTRC work station. When at the work station, you can perform your patent search at the U.S. Patent Office Patent Search page or using the PUBWEST system unassisted. Note that you must be logged into PUBWEST by a Library Staff member. 

Pub EAST and PubWEST are the platforms offered only in the Public Search Facility and PTRCs. They are internal U.S. Patent and Trademark Office databases for use by USPTO patent examiners. These systems are not as user friendly as the web search option. If you choose to use them, please allow extra time to familairize yourself with the systems.

If you desire orientation to either the web search page, PubEast or PubWEST, Jon Cavicchi can asist you in person by appointment. Call 603-513-5139 or email his office. He is also avialable to assist you via phone and chat.
