Appeal No. 2006-0124 Application No. 10/071,301 characteristics," which include "clear in color, castable, stretchable, possess mordant sites than [sic] can react with a dye, be sufficiently swellable in water to be dyed, that is, have its mordant sites exposed and also exhibit good dichroism after appropriate dyeing" (Buzzell, column 5, lines 13-17). The examiner concludes (Answer, page 4) that it would have been obvious to add a crosslinking agent to the adhesive layer, aided by a catalyst such as hydrochloric acid (HCl) (based on column 6, lines 1-5, of Buzzell), "to maintain the dimensional stability of the entire polarizing plate laminate." Appellants argue (Brief, page 4) that Buzzell "does not disclose the advantages of a cross-linking agent for any 'polymer.'" Instead, contend appellants, Buzzell only teaches that adding a crosslinking agent to a mordanting polymer film improves the "dimensional stability" and other characteristics of the mordanting polymer film. Further, appellants add (Brief, page 5) that Buzzell fails to suggest that the characteristics that are improved by the crosslinking agent are applicable to the adhesive layer. Thus, appellants assert (Brief, page 5) that the examiner has failed to establish a motivation for using a crosslinking agent in the adhesive of Buzzell other than in hindsight. We agree. 4Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
