Patent and Trademark Resource Center Program

Linda Hall Library

Linda Hall Library is one of over 80 libraries in the United States that participate in the Patent and Trademark Resource Center (PTRC) Program. The PTRC program is administered by the U.S. Patent and Trademark Office.
Through the PTRC Program, the U.S. Patent and Trademark Office provides participating libraries access to patent and trademark information and resources, including tools the general public can use to conduct self-directed and preliminary patent and/or trademark searching.
Conducting intellectual property research can be a complicated and time-consuming process. The completeness or accuracy of a search rests entirely on the individual doing the search. Reference librarians can provide general instruction in the use of the search tools provided by the U.S. Patent and Trademark Office, but cannot conduct searches for patrons nor provide legal advice. The U.S. PTO recommends that individuals consult an intellectual property attorney for legal advice regarding patent and trademark processes.
To speak with a librarian for further information, please call 816.363.4600 or 800.662.1545, then choose option 2 for the Reference Department, or send an e-mail to
