New Patent License Registration System

On December 13, 2006, Ministry of Economy, Trade and Industry asked for comments on a new registration system of patent comprehensive licenses.

Under current Japanese law, when licensors transfer patent rights or they go bankrupt, licensees are protected only on the condition that their license contracts are registered at Japan Patent Office. However, comprehensive license contracts are widespread in practice which do not identify the patent numbers, or which are not registered for keeping secret to competitors.

Therefore, in order to protect licensees of those patent license contracts, METI proposed a new registration system, which will not require specific patent numbers for registration, and will be disclosed only when disputes should arise.

Comments will be accepted until January 11, 2007.
