[Article / Patents] Cross-border patent infringement in the IoT era (Takeshi Maeda, Patent, 2025 Supplement No. 31)
While retaining traditional territoriality (the principle that a patent’s effect is confined to the territory of that country), the article proposes “flexible application” to ensure the effectiveness of patent rights.
In determining whether an act of working was performed in Japan, it emphasizes not only the actor’s location but also the “place where the act’s result occurs.”
The “place of the result” is defined for each act of working; if it is in Japan, the Japanese patent’s effect extends to it.
