Appeal No. 2000-2223 Application No. 09/040,271 would have suggested to one of ordinary skill in the art that the reversible jackets of Loscher and/or Eastbay Catalog may be modified in a manner that would result in the subject matter of claims 1 or 2. In this regard, we disagree with the examiner’s position on page 5 of the answer to the effect that the differences between the reversible jackets of the applied references and the appealed claims are merely obvious matters of design choice. Rejections based on 35 U.S.C. § 103 must rest on a factual basis. In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 177-78 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968). In making such rejections, the examiner has the initial duty of supplying the requisite factual basis and may not, because of doubts that the invention is patentable, resort to speculation, unfounded assumptions or hindsight reconstruction to supply deficiencies in the factual basis. Id. In the present case, the examiner has failed to advance any factual basis to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the reversible jackets of Loscher or Eastbay Catalog in a manner that would result in the subject matter of claims 1 or 2. The mere fact that the prior art references could be so modified would not have made the modification obvious unless the prior art suggested the desirability of the modification (see In re Gordon, 7Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
