The Intellectual Property High Court, which specializes in patents and trademarks, has decided to widely solicit opinions from parties other than parties on issues in a patent lawsuit regarding the display of comments on videos on the Internet.


It's the first time a high-impact patent litigation has been enforced under new procedures introduced in April to give courts a broader perspective.

Dwango Co., Ltd., which operates the video site Nico Nico Douga, is suing the operating company of FC2 Video for allegedly infringing a patent for displaying comments on videos being played. It's a trial.



Under the amended Patent Act, which came into force in April, the impact of judgments on patent litigation may affect not only the parties concerned but also many industries in Japan and overseas, and it is necessary to consider this from an international perspective. As a result, a system was established in which opinions can be solicited widely from the general public and used as evidence when the court deems it necessary.



According to the Intellectual Property High Court, this is the first time to solicit opinions using the new system.



Details such as issues of dispute are published on the court's website, and if you wish to submit an opinion, please mail your opinion to the Intellectual Property High Court by the end of November.



The collected opinions can be used as evidence in the trial after the plaintiff side and the defendant side confirm the contents.
