[Title of the patent] “Antipruritic agent”

[Key issue] Whether the application for registration of patent term extension (PTE application) falls under Article 67-3, paragraph (1), item (i) of the Patent Act

Court rescinded a JPO’s appeal decision which maintained an examiner’s decision to reject a PTE application.  The examiner’s reason for rejecting the PTE application was that the approved drug having nalfurafine hydrochloride as the active component was not contained in the patent invention having nalfurafine as the active component and therefore it could not be found that upon working the patent invention, it was necessary to receive the disposition specified by Cabinet Order as set forth in Article 67, paragraph (2) of the Patent Act.

[Title of the patent] “(Meth)acrylic acid ester copolymer”

[Key issue] Inventive step (Article 29, paragraph (2) of the Patent Act)

Court rescinded a JPO’s revocation decision, stating that the patent invention could have been easily conceived of by a person skilled in the art based on Cited Invention 1, since there was little motivation to improve Cited Invention 1 to solve the problem of the patent invention because the technical field and the problem are not necessarily the same for the patent invention and Cited Invention 1 and according to the disclosure of Citation 1 (Exhibit Ko 7), there is little reason for a person skilled in the art to select the two kinds of monomers, a monomer containing epoxy groups and a monomer containing hydroxy groups, from among multiple combinations disclosed in Citation 1.
