Appeal 2007-1485
Application 10/943,944
Examiner also recognized that Jarvis discloses the film material should have
chemical resistant properties (Answer 5). The Examiner found that Inaba
describes fluororesin film materials have chemical resistant properties. In
addition to chemical resistant properties, Inaba discloses fluorine-containing
ethylenic polymers have heat resistant properties, and have a low
permeability against solvents and fuels (col. 1, ll. 31-34). The Examiner
concluded that forming the wide film material of Jarvis utilizing a
fluororesin material would have been obvious to a person of ordinary skill in
the art (Answer 5-6).
Jarvis describes a method of joining two or more substrates with a
thermoplastic tape through the use of adhesive and physical bonding with
the substrates. Jarvis discloses that the formed seam has excellent tensile
strength and barrier properties (Paragraph 0020). Jarvis discloses a wide
variety of materials are suitable for use as the substrate and the thermoplastic
tape (Paragraphs 0022-0023). Jarvis discloses that the substrates to be
joined are placed in communication with the tape structure where heat and
pressure are applied to seal the materials to form a seam (Paragraph 0031).
Appellants have not contested that it would have been obvious to a
person of ordinary skill in the art to form a fluororesin film having a width
of from 1-150 m as required by the claimed invention. Rather, Appellants
argue that the combination of Jarvis and Inaba does not disclose or suggest
the presently claimed invention because there is no thermoplastic between
the respective fluororesin sheets and the present invention requires press
bonding at the overlapping edges (Br. 8).
