            Appeal No. 2007-0196                                                              2             
            Reexamination Control No. 95/000,009                                                            
            35 U.S.C. 134 from a final decision of the examiner favorable to patentability.                 
            Such an appeal places the requester in the unaccustomed position of having both                 
            the burden of showing error in the examiner's decision and the ultimate burden of               
            proof on the question of patentability.                                                         
                   We—                                                                                      
                         AFFIRM the decision not to reject the claims as anticipated;                       
                         REVERSE the decision not to reject the claims as obvious; and                      
                         REMAND for examination consistent with this opinion.                               
                                             ANTICIPATION                                                   
                   Lord argues that the following patent anticipated Congoleum's claims under               
            35 U.S.C. 102:                                                                                  
                   H.A. Chen, R. Judd, I.B. Rufus, and J.R. Shultz, "Contrasting gloss                      
                   surface coverings optionally containing dispersed wear-resistant                         
                   particles and methods of making the same", U.S. Patent 6,228,463 B1                      
                   (issued 8 May 2001) ("Chen").                                                            
            Lord is vague about which provision of § 102 applies.1  The examiner                            
            characterizes the rejection as based on § 102(b).  See, e.g., Action Closing                    
            Prosecution 4 (mailed 7 April 2003).  Since the application that produced                       
            Congoleum's patent was filed before Chen issued, a rejection under § 102(b) is not              
            possible.   In failing to state a precise basis for the rejection, Lord arguably failed         
            to make out a facially complete case in the first instance.  The examiner should not            
            be placed in the position of having to guess what the requester really meant before             
            proceeding with the examination.                                                                

                                                                                                           
            1 When urging obviousness, on the other hand, Lord specifies that the statutory                 
            basis is 35 U.S.C. 103(a), although in this case the precision is not as important.
