What is the PTRC

The Pennsylvania State University Libraries is home to 1 of 3 Patent and Trademark Resource Centers (PTRC) in the State of Pennsylvania. The PTRC is housed in the Physical and Mathematical Sciences Library on the University Park Campus in State College, PA. As a PTRC, Penn State Libraries representatives can:

  • Provide access to USPTO resources
  • Direct you to information and explain the application process and fee schedule
  • Demonstrate how to use search tools to conduct a patent or trademark search
  • Show you a directory of local patent attorneys who are licensed to practice before the USPTO
  • Offer classes on intellectual property (varies by location)
  • Offer assistance on how to do historical research on patents and trademarks
  • Show you how to track current research by company or nonprofit
  • Help you find assignee information and much more.
