Appeal No. 96-3720 Page 2
Application No. 08/230,825
claims 1-4 as amended subsequent to the final rejection. These
are all the claims remaining in the application.
The subject matter on appeal relates to a material which
comprises two sheets of microporous plastic film bonded
together with an adhesive, the plastic film having pores of a
sufficient size such that the adhesive migrates into the pores
forming a continuous layer between the two sheets of film.
Further details of this appeal subject matter are set forth in
representative independent claim 1 which reads as follows:
1. A material for use in the manufacture of surgical
gowns and the like and which comprises two sheets of
microporous plastic film bonded together with an adhesive, the
plastic film having pores of a sufficient size such that the
adhesive migrates into pores forming a continuous layer between
the two sheets of film to provide a breathable but
substantially liquid and viral impervious laminated core, and
two layers of fabric that cover and protect said core.
The reference relied upon by the examiner as evidence of
obviousness is:
Lumb et al. (Lumb) 5,204,156 Apr. 20,
1993
All of the claims on appeal stand rejected under 35 U.S.C.
§ 103 as being unpatentable over Lumb.
