Appeal No. 95-2930
Application No. 08/043,953
As a final point, we note that U.S. Patent No. 4,781,799
issued to Herbert, Jr. et al. on November 1, 1988 (Herbert)
describes removing an electroformed hollow article (sleeve)
from a mandrel by sliding the article away from the mandrel.
See column 20, lines 35-47 and column 22, lines 22-39. Upon
return of this application, the examiner is advised to
determine whether the Herbert reference affects the
patentability of the claimed subject matter. That is, the
examiner is advised to determine whether sliding the article
necessarily involves twisting (circumferential movement) and
pulling the article or whether one of ordinary skill in the
art would have reasonably expected that twisting and pulling
would have enhanced the sliding of the article away from the
mandrel.
In view of the foregoing, we reverse the examiner’s
decision rejecting the appealed claims under 35 U.S.C. § 103
and remand
