The “TM5″ is a framework through which five intellectual property offices namely, the National Intellectual Property Administration, PRC (CNIPA), the European Union Intellectual Property Office (EUIPO), the Japan Patent Office (JPO), the Korean Intellectual Property Office (KIPO) and the United States Patent and Trademark Office (USPTO) exchange information on trademark-related matters, and undertake cooperative activities for their mutual benefit, and for the interests of their respective trademark filers and registrants.
The TM5 is an outgrowth of the Trademark Trilateral, a cooperative framework that JPO, EUIPO and the USPTO first undertook in 2001. That framework was expanded to include KIPO and CNIPA in 2011 and 2012 respectively, and the group became known as “TM5.”
Given the usefulness of the discussion on design issues within the TM5 collaboration framework, design sessions have been held in parallel with the trademark sessions since 2010.


Through exchange of information on practices and programs as well as common projects aiming at the harmonization or improvement of trademark procedures, TM5 strives to promote cooperation and collaboration between members and contribute to increasingly user-friendly and, if possible, interoperable trademark systems.
