Appeal No. 2000-1006 Application 08/974,148 different mechanism than that which is utilized by Jackson.3 Specifically, appellant distinguishes the present invention from that of Jackson as follows: Jackson uses a high pH solution of at least 10.5, and he states that the rosin reacts with the alkali to form a water soluble soap. Applicant is removing insoluble organic materials that do not react with either alkali or acid to form soluble products. Instead, applicant, using hydrogen peroxide, ionizes such inorganic [sic, organic] materials to [sic] as to give them a charge, either positive or negative depending on the nature of the surface. When the organic material and the surface it is adhered to have the same charge, they repel each other, loosening the bonds between them and allowing the organic material to be removed. Appeal Brief, page 6. In deciding patentability issues under 35 U.S.C. § 103, “[a]nalysis begins with a key legal question -- what is the invention claimed?” Panduit Corp. v. Dennison, 810 F.2d 1561, 1567-68, 1 USPQ2d 1593, 1597 (Fed. Cir.), cert. denied, 481 U.S. 1052 (1987). Again, as correctly observed by the examiner, claim 1 merely requires that the oxidant is present in an amount 3 “Jackson has no understanding of the role played by IEP versus pH, or even of the role of pH versus IEP of the surface. Nor does Jackson teach the role for hydrogen peroxide required by and taught by applicant.” Appeal Brief, page 7 (emphasis added). 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
