Matsushita v. Justsystem ruling by Tokyo District Court on 1 February 2005

Jump to: navigation, search

Justsystem Corporation v. Matsushita Electric Industrial Co. Heisei 17 (NE) 10040 (2005), Japan. Or, using those companies' newer names, JustSystems Corporation v. Panasonic.

In February 2005, a Tokyo District Court (CHECKTHIS) found JustSystems to be violating a software patent of Panasonic on help functionality in the Ichitaro word processor because it is indirect infringement of Article 101, Subparagraph 2 of the Patent Law. But, on September 30, 2005, the then-newly formed Intellectual Property Court overturned that ruling.

(Can you help? This article should probably focus on the September 2005 IP Court case, right? That would include renaming the article.)
