Appeal No: 1997-1820 Application No: 08/313,941 low phosphorus content carbon was commercially available at the time of the invention. While Hassler teaches that low or no phosphate content carbon was commercially available, it does not teach that low or no phosphorus content carbon was commercially available. Note that Richardson teaches that phosphate ions are not toxic in catalysts. The prior art does not contain a suggestion to modify Miller by acid washing the carbon support portion of the catalyst. While one skilled in the art would have been motivated to select a low phosphorus content carbon for use in manufacturing a catalyst, the examiner has not provided sufficient evidence to show that low or no phosphorus content carbon was commercially available at the time of the invention. Accordingly, the examiner's rejection of claims 1-13, 17- 20, and 24 is REVERSED. The examiner rejects claims 21 and 23 as being unpatentable over Miller, Richardson, Goleva, Hassler and -11-Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
