Appeal No. 2000-0701 Application No. 08/816,471 conductive polymer element. The surface of the metal foil electrode that is in direct contact with the conductive polymer element has a center line average roughness of at least 1.4, and a reflection density of at least 0.70. Claim 1 is illustrative of the claimed invention, and it reads as follows: 1. An electrical device which comprises (A) an element composed of a conductive polymer which exhibits PTC behavior; and (B) at least one metal foil electrode which (1) comprises a base layer, a surface layer, and an intermediate layer which is positioned between the base layer and the surface layer, (a) the base layer comprising a first metal, (b) the intermediate metal layer comprising a metal which is different from the first metal, and (c) the surface layer (i) consisting essentially of a second metal, (ii) having a center line average roughness Ra of at least 1.4, and (iii) having a reflection density Rd of at least 0.70, and (2) is positioned so that the surface layer is in direct physical contact with the conductive polymer element. No references were relied on by the examiner. Claims 1 through 6, 9, 10 and 12 through 20 stand rejected under 35 U.S.C. 2Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
