2023 (Gyo-Ke) 10034 [Method of Manufacturing a Raised-Fiber Sheet] <Hibiku Shimizu>
*Usurped application established (JPO decision set aside)
The true inventor's statement: pile length 2–3 mm
Claim 4 specifies 3–10 mm, so the statements are consistent.
Even if the usurping applicant devised various refinements to the dyeing process, none was included in the claims.
⇒ Could adding “the configuration devised by the usurping applicant” through correction have complicated the issue?
*Since patentability existed even without “the configuration devised by the usurping applicant,” perhaps this would merely become a violation of the joint-application requirement. If patentability were recognized only after adding that configuration through correction, the invention might have been solely that of the inventor named in the publication. A judgment offering lessons on points to consider when filing alone for an invention involving others!!
