About the PTDL
In January, 1990, the Chester Fritz Library was designated the 67th U.S. Patent and Trademark Depository Library. The Patent and Trademark Depository enables the University community to access over 5 million patents and 2 million trademarks issued by the United States Patent and Trademark Office.
The holdings of the depository consist of full design, utility, plant and reissue patents from 1960 to the present. The Depository Library also contains a complete run of the Official Gazette of the Patent and Trademark Office and various indexes and informational publications regarding patents and trademarks.
