The Government Information Center participates in the Patent and Trademark Resource Center (PTRC) program as overseen by the United States Patent and Trademark Office (USPTO). While legal questions cannot be answered by library staff, librarians can assist patrons in the very basics of patent and trademark searching such conducting a patent search,  a trademark search, or locating a patent attorney. The patent and trademark links listed on this page can be accessed from any computer.

Due to technical difficulties, access to PubEast or PubWest, located at other libraries participating in the PTRC program, is not available at SFPL at this time. The closest PTRC library to SFPL is San Jose Public Library, located approximately 50 miles south of San Francisco. The California State Library, approximately 90 miles east of San Francisco and located in Sacramento, is also in the PTRC program.
