Appeal No. 2001-0651 Application 08/134,187 reasonable appears to be either identical with or only slightly different than a product claimed in a product-by-process claim, a rejection based alternatively on either section 102 or section 103 of the statute is eminently fair and acceptable. Id, at 688. The rationale for this conclusion is that the Patent and Trademark Office is not equipped to manufacture products by the myriad of processes put before it and then obtain prior art products and make physical comparisons therewith. Thus, this burden is shifted to appellants in those instances where prior art is applied by the examiner against product-by-process claims and appellants must specifically point out or demonstrate how the process limitations structurally distinguish the claimed product from the product of the prior art, which may be made by a different process. As is apparent from the above-noted case law, appellants are normally only put to the burden of specifying the exact structural limitations imposed on the claimed product by the process limitations when the examiner has applied prior art which teaches, discloses or makes obvious a product which reasonably appears to be either identical with or only slightly different than a product claimed in a product-by-process claim.
