Appeal No. 1998-1726 Application No. 08/681,117 specification Holmes ‘809. We will therefore limit our discussion to the Holmes ‘809 reference. We find Holmes is directed to a method for forming in a semiconductive conjugated polymer at least first and second regions having different optical properties. The invention also includes an electroluminescent device including a semiconductive conjugated polymer comprising first and second regions having different optical properties. The method of making a semiconductive conjugated polymer comprises forming a layer of a precursor polymer and permitting the first region to come into contact with a reactant, such as an acid, and heat while permitting the second region to come into contact with a lower concentration of the reactant. (Col. 2, ll. 8-19). The preferred precursor polymers include poly(para-phenylene- 1,2- ethanediyl) polymer, a poly(2,5 dimethoxy para-phenylene-1,2-ethanediyl) polymer or poly(thienylene-1,2-ethanediyl) polymer. (Paragraph bridging cols. 4-5). A suitable precursor polymer is represented by Formula I which is converted to a partially conjugated poly(arylenevinylene) polymer represented by Formula II. (Col. 14, ll. 1- 8). We find the polymer represented by Formula II of Holmes is a specie of the poly(arylenevinylene) polymer represented by formula (I) of claim 1. Holmes does not disclose irradiating the poly(arylenevinylene) polymer represented by Formula II to form a pattern. - 4 -Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
