Appeal No. 96-4193
Application No. 08/267,049
OPINION
The disc cartridge liner of appealed claim 1 comprises
entangled thermoplastic fibers and entangled regenerated
cellulose fibers and refined cellulose fibers. The examiner
finds that Takemae discloses a disc cartridge liner comprising
a thermoplastic fiber and a regenerated cellulose fiber
(Answer, page 3). The examiner recognizes that Takemae does
not disclose refined cellulose fibers as required by appealed
claim 1 (Answer, page 4). The examiner cites Vogt (M1159V/52)
for the disclosure of “a protective sleeve of a video record
comprising fibers made by plastics or semi-synthetic material
consisting of a modified cellulose (a refined cellulose fiber
inherently).” (Id.). The examiner concludes that it would
have been obvious to make the disc liner of Takemae with both
a regenerated cellulose fiber and a refined cellulose fiber
“as inherently taught by M1159V/52 [Vogt].” (Id.).
The examiner does not provide any factual support for the
finding that the “modified cellulose” of Vogt is “inherently”
a refined cellulose fiber. See the specification, page 9,
where appellant discloses the preparation and characteristics
