IP High Court, Reiwa 6 (Gyo-Ke) 10039 [Bag having embossing] <Presiding Judge Hibiku Shimizu>
Cited inventions 1 and 2 both belong to the same technical field of “embossing in which a film is press-worked using rolls.”
The “matte-textured portion” of cited invention 1 and the “multiple rows of waves” of cited reference 2 have the common action and function of “expressing a pattern by forming minute unevenness on the film surface without providing a printing process.”
⇒ Readily conceivable (no inventive step).
★ Numerical ranges are design matters:
The numerical ranges of the period and height of the unevenness (such as 0.1 µm–1 mm in the application and 500 µm–2 mm in cited reference 2, which overlap) are merely design matters that a person skilled in the art could select as appropriate according to pattern visibility and other considerations.
