Appeal 2006-3166 Application 09/843,582 The Examiner relies on the following prior art reference as evidence of unpatentability: Andros US 5,844,030 Dec. 1, 1998 The rejection as presented by the Examiner is as follows: 1. Claims 14, 19, and 20 are rejected under 35 U.S.C. § 102(b) as unpatentable over Andros. Appellants contend that Andros does not disclose a brush that includes a “complexing agent adapted to chemically bond to metal particles” as recited by each of the claims on appeal (Br. 3). The Examiner contends that Andros discloses a brush having a complexing agent for chemically bonding metal particles (Answer 3-5). We AFFIRM. ISSUE Whether Andros discloses a brush or scrubber having a “complexing agent adapted to chemically bond to metal particles” as required by claims 14, 19, and 20. FINDINGS OF FACT Appellants invented a scrubber brush or pad having a reactive surface for contacting a substrate to remove metal particles therefrom (Specification 2: 7-25; 3: 27-29). The reactive surface of the brush or scrubber may comprise a complexing agent such as a chelating reagent (Specification 3: 30-31). The complexing agent “reacts” with the metal particles to remove them from the surface of the substrate (Specification 3: 30-33; 4: 1-2). 3Page: Previous 1 2 3 4 5 6 7 Next
