          Appeal No. 2003-0754                                                         
          Application No. 09/553,630                                                   

          On page 2 of the Brief, appellants state that the claims                     
          stand or fall together.  We therefore consider claim 16 in this              
          appeal.  37 CFR § 1.192(c)(7) and (8)(2000).                                 
               For the reasons set forth below, we reverse each of the                 
          rejections.                                                                  
            As a preliminary matter, we note that on pages 3-4 of the                  
          Brief, appellants argue that this appeal should be decided as a              
          matter of law in favor of appellants.  Appellants state that the             
          present application is a divisional application with claims                  
          drawn only to a coated article.  Appellants state that the clear             
          aqueous cathodic electrocoating composition has already been                 
          deemed patentable by the Patent Office in U.S. Patent No.                    
          6,123,866.  Appellants argue that because the composition claims             
          have been deemed patentable, the product made from the                       
          composition should be also deemed patentable (as a combination).             
          In response, the examiner states that he is not bound by                     
          the opinions of a different examiner regarding patentability of              
          the composition claims.  (Answer, page 5).                                   
          We note that patent disclosures are often very complicated                   
          and different examiners with different technical backgrounds and             
          levels of understanding may often differ when interpreting such              
          documents.  In re Dayco v. Total Containment Inc., 329 F.3d                  
          1358, 1365-66, 66 USPQ2d 1801, 1808 (Fed. Cir. 2003).  As such,              
          an examiner is not bound to follow another examiner’s                        
          interpretation.  Also, compare In re McDaniel, 293 F.3d 1379,                
          1383-84, 63 USPQ2d 1462, 1467-86 (CAFC 2002), wherein the Court              
          stated that it is well settled that the prosecution of one                   
          patent application does not affect the prosecution of an                     
          unrelated application.  See also In re Wertheim, 541 F.2d 257,               
          264, 191 USPQ 90, 97 (CCPA 1976).  (“It is immaterial in ex                  
          parte prosecution whether the same or similar claims have been               

                                           3
