Patent and Trademark Resource Center (PTRC)

Welcome to the Patent and Trademark Resource Center


This is a guide of recommended information resources for patent and trademark research. 

       USPTO Logo                

Wright State University Libraries maintain a Patent and Trademark Resource Center (PTRC) in the Paul Laurence Dunbar Library.  As an official PTRC of the United States Patent and Trademark Office (USPTO) we have a formal agreement to provide assistance to the general public in the use of patent and trademark resources provided by the USPTO. 

Recognizing that intellectual property research is a complex endeavor with important legal and financial implications, our services are designed to support the individual or corporate/legal researcher's efforts to conduct self-directed and preliminary research.

Library staff cannot offer legal advice, conduct searches, assist in writing applications, guarantee completeness of searches, or advise on ideas. All final research, regarding intellectual property determinations, should be done in consultation with proper intellectual property legal professionals.

The Reference staff will make every effort to protect the confidentiality and privacy of researchers.
