Appeal No. 2005-2320 Application 09/778,895 the watermark unit, and if we assume for the sake of argument that it determines whether the output data from the disk 8 is encrypted data, then a decoder1 to extract digital audio data from the decrypted data is not located in Matsumoto. Accordingly, the anticipation rejection of claims 1, 3 through 5, 7 through 11 and 13 is reversed because each and every claimed element is not located in Matsumoto. For all of the reasons expressed supra, and for the additional reason that the record is silent as to a reason why the skilled artisan would have attributed any other decoding functions to the decoder 25, the obviousness rejection of claims 2, 6, 12 and 14 is reversed. 1 Matsumoto is silent as to the decoder 25 performing more than a single decoding function. 4Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
