Appeal No. 1998-1726 Application No. 08/681,117 BACKGROUND According to Appellants, the invention is directed to a process for pattering a fluorescent poly(arylenevinylene) (PAV) film. These films are used in electroluminescent devices. (Brief, page 2). Claims 1 and 8 which are representative of the invention are reproduced below: 1. A process for forming a pattern which comprises irradiating with light a film of a poly(arylenevinylene) polymer represented by formula (I) wherein Ar is a substituted or unsubstituted divalent aromatic hydrocarbon group or a substituted or unsubstituted divalent heterocyclic ring group, and the aromatic hydrocarbon group and the heterocyclic ring 1 2 group may be a fused ring, R and R , independently or each other, are selected from the group consisting of H, CN, alkyl, alkoxy, a substituted aromatic hydrocarbon group, an unsubstituted aromatic hydrocarbon group, a substituted aromatic heterocycle group and an unsubstituted aromatic heterocycle group, wherein the unsubstituted or substituted aromatic hydrocarbon group and the unsubstituted or substituted aromatic heterocyclic group may be fused rings, and n is an integer from 5 to 30,000. 8. An organic electroluminescent device comprising a layer of a patterned poly(arylenevinylene) polymer film produced by the process according to claim 1. As evidence of unpatentability, the Examiner relies on the following references: Holmes (Holmes ‘809) 5,328,809 Jul.. 12, 1994 - 2 -Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
