                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).                      

                                                      3
