IP High Court, Heisei 25 (Ne) No. 10007 — Stirring and granulating apparatus (Judge Shitara)
*Two products delivered on the same day were found to have been sold as an integrated unit.
→ Direct infringement established!
(Excerpt from the judgment, translated; portions omitted)
The defendant’s product sold to Freund and exhibited at the exhibition either had a stirring blade satisfying element D of the patented invention (“GM blade”) installed from the outset, or was intended to have it installed, and was sold together with the GM blade [...] as an integrated unit. [...] The blades are used exclusively in the stirring granulators manufactured by the defendant; therefore, their transfer constitutes indirect infringement of the patent (Patent Act, Article 101(i)).
