Patent and Trademark Resource Center (PTRC) Program

An Overview of the PTRC Program

North Carolina State University Libraries is currently a Patent and Trademark Resource Center (PTRC). PTRCs are those designated by the U.S. Patent and Trademark Office (USPTO) to receive and house copies of patent and trademark materials, to make them freely available to the public, and to actively disseminate patent and trademark information.

The Libraries provide

  • access to the PubWEST and PubEAST databases for patent searching needs that are not met by the publicly accessible online USPTO databases;
  • access to the Derwent Innovations Index database (restricted to NC State students, faculty, and staff) for international patent searching, as well as enhanced keyword searching;
  • a large research collection that includes works on intellectual property topics, as well as "how-to" books for students, inventors, engineers and academics.

The Patent Librarian can

  • provide a brief orientation to available materials and resources, as well as general guidance on searching patents and trademarks;
  • help you identify historical patents and inventors using print materials, such as Patent Indexes and Official Gazettes;
  • contact experts at the USPTO for specialized questions or research needs beyond the scope of the Libraries' service;
  • point you to online tutorials and other reliable and informative web resources.

Other NC State Patents Resources

  • NC State University's Office of Technology Transfer (OTT) works closely with faculty, staff and students to ensure proper disclosure of inventions on campus. They also provide substantial assistance in assessing the commercial viability of inventions and bringing them to market. For more information visit their Inventor Resource Center web pages: http://research.ncsu.edu/ott/
  • Special Collections' Online Exhibit on NC State Patents (June 1-30, 2000): /archivedexhibits/patents/
