We also provide instruction and develop course-specific online resource guides.

Patent and Trademark Resource Centers are located nationwide.

Contact a patent/trademark attorney for a complete search, legal advice, and submission of a patent or trademark application.

A search of all prior art, including patented and patent pending inventions in the U.S,, should be conducted in order to determine if an invention has been publicly disclosed and is therefore not patentable.

A preliminary patent search is useful as an initial survey in determining whether or not an invention has already been publicly disclosed. It is not equal to a complete, professional search of all prior art in existence, which includes both U.S. and foreign patents, also non-patented literature such as technical papers and articles.

The OSU Patent and Trademark Resource Center (PTRC) is a partner with U.S. Patent and Trademark Office (USPTO) and assists inventors with preliminary patent and trademark research by appointment.

OSU PTRC staff cannot:

  • Perform patent or trademark searches for users
  • Provide advice on how to file a patent or trademark application
  • Interpret intellectual property law
  • Offer legal advice or opinions

Contact a patent attorney for a complete, professional search. A list of registered attorneys and agents in the U.S. is available on the USPTO website. Search by city or state:
