(answer, pages 5 and 6), is of the view that the Chikaishi
document is clearly, highly relevant, and analogous prior art.
It is well settled that prior art relevant to an obviousness
determination encompasses not only the field of the inventor's
endeavor but also any analogous arts. Heidelberger
Druckmaschinen AG v. Hantscho Commerical Products Inc., 21 F.3d
1068, 1071, 30 USPQ2d 1377, 1379 (Fed. Cir. 1994). The test of
whether a reference is from a nonanalogous art is first, whether
it is within the field of the inventor's endeavor, and second, if
it is not, whether it is reasonably pertinent to the particular
problem with which the inventor was involved. In re Wood,
599 F.2d 1032, 1036, 202 USPQ 171, 174 (CCPA 1979). A reference
is reasonably pertinent if, even though it may be in a different
field of endeavor, it is one which because of the matter with
which it deals, logically would have commended itself to an
inventor's attention in considering his problem. In re Clay,
966 F.2d 656, 659, 23 USPQ2d 1058, 1061 (Fed. Cir. 1992).
