Tokyo District Court, 2022 (Wa) 11921 [Side Ditch and Catch Basin] <Sugiura>

*At the March 2021 meeting, the plaintiff expressed the understanding that this was a contractual issue rather than patent infringement.

Considering the sequence of events, at that meeting the plaintiff gave Litag its consent to Litag's licensing agreement with the defendant retroactively to the date the agreement was concluded.
