Appeal 97-1804
Application 08/329,042
48. Ultimately, however, removal of the water
soluble component opens pores in the compact (col. 4, lines 4-
5). 49. Specifically, heating the compact is said
to vaporize the water insoluble component and resulting gases
escape from the compact through pores formed by removal of the
water soluble component (col. 4, lines 41-45).
Applicant's argument with respect to Hens
50. Applicant maintains that Hens does not describe
a "layer" within the meaning of claim 1.
51. According to applicant, a "layer" is "[a] single
thickness, coating, or stratum spread out or covering a
surface." The American Heritage Dictionary of the English
Language (1969) (attached as Exhibit A to the Appeal Brief).
52. Applicant points to the drawings to support his
argument that the invention relates to a "layer" (see Figs. 1
and 2, supra Finding 12).
53. Accordingly, applicant reasons that Hens does
not describe a continuous, non-porous, self-cross-linked OPC
layer of PVB (Appeal Brief, page 6).
