However, sale of Princeton logo merchandise to Princeton University departments and to authorized student or alumni groups are exempt from the royalty charge, although such goods must still be purchased from a licensed vendor. There is a special clause in the licensing agreement for official royalty-exempt vendors, but the procedures and approval requirements remain the same as for commercial vendors. Licensees are required to submit product samples and designs for approval prior to production of the goods. Licensees are encouraged to be creative with their designs. The University works with licensing agents in each of these territories to find licensees, shop the market for infringement, and to serve as the local coordinator for the various programs.
International licensees follow the same requirements as their U.S. colleagues.
The legal and illegal use of Princeton's trademarks throughout the world is monitored by an international trademark watch service. On the domestic front, staff from the Trademark Office make regular visits to local retailers to ensure that only officially licensed merchandise is being sold. Trademark licensees, retailers, as well as Princeton students and alumni, also serve as a network for identifying unlicensed merchandise.
