The prior art reference Masayuki does not provide the motivation to arrive at the claimed subject matter. According to the rejection, Masayuki teaches using an ethoxylated acrylate monomer that is poorly miscible with a chosen liquid crystalline material and because of this has a phase separation problem that is controlled by the addition of a miscible oligomer mixture. However, we observe that Masayuki does not mention, let alone suggest, selecting a liquid crystalline material and an ethoxylated acrylate monomer that is miscible with the selected liquid crystalline material. We are not persuaded that a potential phase separation problem between a monomer and a liquid crystalline material leads one of ordinary skill in the art to select a liquid crystalline material and an ethoxylated acrylate monomer that is miscible with the selected crystalline material. Even if we accept the fact that routine experimentation would allow a person of ordinary skill in the art to obtain such a mixture, this does not explain why one of ordinary skill in the art would desire such a mixture or be guided toward such a mixture. Specifically, while routine experimentation on a known set of components may be obvious, we do not see where Masayuki or the prior art in general directs one of ordinary skill in the art to select appellants’ particular materials, i.e., a liquid crystalline material and an ethoxylated acrylate monomer that are miscible with each other. The Office has the burden of establishing a prima facie case of obviousness. Based upon the record presented, we are unable to conclude that one of ordinary skill in the art would have been motivated to select the appropriate liquid crystalline material and (1a) an ethoxylated 10Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
