Appeal No. 2006-2247
Reexamination Nos. 90/006,554 and 90/006,894
1 Our invention balances the foregoing factors and achieves
2 superior oxidation results by doing so. [Boeckh Declaration,
3 ¶6.]

5 49. Dr. Boeckh states: “Dunn was not able to solve the above problems
6 solved by our invention because the process of that patent oxidizes the
7 polymer in acetic acid medium entirely (or some other organic
8 solvent), and leaves a large amount of acid to handle at the end of the
9 reaction.” (Boeckh Declaration, ¶7.)
10 50. Dr. Boeckh asserts: “The examples of the ‘684 patent show that our
11 process can be used to achieve degrees of oxidation of from, for
12 example, 76% (Example 6) to 92% (Example 2) in the PVNO
13 produced.” (Boeckh Declaration, ¶8.)
14 51. Dr. Boeckh states that Exhibits 1 and 2, which are attached to the
15 declaration, documents and summarizes additional experiments
16 supporting the argument that the claimed process “provides superior
17 oxidation results, including the ability to achieve oxidation degrees for
18 the PVNO product above 90% in an acid medium containing at least
19 25% water and the specified catalyst.” (Boeckh Declaration, ¶¶10-
20 11.)
