Appeal No. 1999-1810 Application 08/288,433 appellant’s process (brief, page 7). This argument is not well taken because the patentability of the solution recited in product-by-process claim 16 is determined based on the product itself, not on the process for making it. See In re Thorpe, 777 F.2d 695, 697, 227 USPQ 964, 966 (Fed.

The appellant argues that the solution recited in claim 16, because it is the product of an oxidation process, differs from seawater (brief, page 7; reply brief, page 1). The process recited in claim 19, which is used to make the solution recited in claim 16, and the process recited in claim 1, from which claim 19 depends, have the transition term “comprising”, which opens the claims to non-recited steps.
