Appeal No. 1997-1516 Application No. 08/326,501 Fagan 4,783,354 Nov. 08, 1988 Appellant's claimed invention is directed to a release liner carrier web comprising a paper substrate, a polypropylene coating on one side of the substrate, and a protective sealing layer, such as an acrylic resin, on the other side of the substrate. Appealed claim 2 additionally recites a silicone release layer on the polypropylene layer. According to appellant, the sealant, or undercoat, layer "traps loose fibers of the paper substrate and prevents them from clogging machinery associated with the production or handling the release sheet." (page 3 of principal brief). In addition, appellant explains that the protective sealant layer "promotes ready peelability of a suitable label from the present release sheet" by seeping through the substrate and contacting the silicone release layer (page 3 of principal brief). Appealed claims 1, 2, 6, 8 and 9 stand rejected under 35 U.S.C. § 102(b) over Hosoda. The appealed claims also stand rejected under 35 U.S.C. § 103 as follows: 3Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
