Bamberg v. Dalvey, No. 15-1548 (Fed. Cir. 2016)
Annotate this CaseAppellants Ulf Bamberg, Peter Kummer, and Ilona Stiburek (collectively, "Bamberg") appealed the Patent Trial and Appeal Board’s consolidated interference proceeding decision refusing to allow their claims to four patent applications because the specification failed to meet the written description requirement of 35 U.S.C. 112. The involved claims disclose a method for the transfer of printed images onto dark colored textiles by ironing over a specialty transfer paper. During the interference proceeding, Appellees Jodi Dalvey and Nabil Nasser (collectively, "Dalvey") filed a motion alleging that Bamberg’s claims were unpatentable for lack of written description. Dalvey alleged that the claims recited a white layer that melted at a wide range of temperatures, but Bamberg’s specification only disclosed a white layer that did not melt at ironing temperatures (i.e., below 220°C). Therefore, Dalvey argued that Bamberg’s specification failed to meet the written description requirement because it did not disclose an invention in which the white layer melted at temperatures below 220°C. The Federal Circuit Court of Appeal concluded that the Board properly construed the claims, and substantial evidence supported the Board’s determination that Bamberg failed to meet the written description requirement, and because it was not an abuse of discretion to deny Bamberg’s motion to amend.
