CourtDecision (repairing sliding door)

[Title of the patent] “Method for repairing sliding door device and repaired sliding door device”

[Key issue] Literal infringement (Article 70 of the Patent Act)

IP High Court judged in a patent infringement case that the appellant’s device did not belong to the technical scope of the patent invention, since the device did not satisfy “substantially the same height” of the phrase “an upper end of the behind wall and an upper end of a lower frame for repair have substantially the same height” of the patent claim, on which point the district court had made an opposite judgement.
