Appeal No. 95-2270
Application 08/005,856
invention include natural rubber, silicone rubber,
acrylonitrile rubber, polyurethane rubber, polyisobutylene,
acrylic polymers and other like substances.
27. In various examples (col. 7), Doehnert describes
pressure-sensitive adhesives made from mixtures of natural and/or
synthetic gum-like substances (Examples 1-3 and 7), as well as
adhesives made from a single natural or synthetic gum-like
substances (Examples 4-6).
The examiner's rejection
28. The examiner rejected claims 45-54 as being
unpatentable under 35 U.S.C. § 103 over the combined disclosures
of Goodwin and Doehnert.
29. The examiner found that Goodwin describes "the
incorporation of compounds which act as cross-linking agents
specifically at column 2, line 45+" (Examiner's Answer, page 2).
30. The examiner also found that the sole difference
between the subject matter of claim 45 and Goodwin was that
Goodwin did not describe the presence of the organic pressure-
sensitive adhesive (Examiner's Answer, page 3).
31. The examiner determined, however, that the use of
a mixture of an organic pressure-sensitive adhesive and a silicon
pressure-sensitive adhesive is described by Doehnert.
