Appeal No. 1997-2446 Application 08/223,351 functionality to the polymer and can introduce salts into the product. Again, see Holy at column 2, lines 8 through 12. Appellants contend that even if a prima facie case of obviousness has been established from the combined teachings of Holy, Hughes and SE, evidence of unexpected results found in TABLE 2 and TABLE 1 of the specification at pages 31 and 27, respectively, are adequate to rebut the prima facie case of obviousness. Initially, and contrary to appellants' arguments, in submitting evidence to establish unobvious results, it is appellants that have the burden of indicating how the examples asserted to represent the claimed process are considered to relate to the examples intended to represent prior art, and particularly to indicate how the prior art examples represent the closest prior art. Moreover, such evidence relied upon must also be reasonably commensurate in scope to the subject matter claimed. Further, such evidence should establish that the differences in results obtained are in fact unexpected to a person of ordinary skill in the art and are of practical significance.
