          Appeal No. 2005-2463                                                        
          Application No. 10/235,443                                                  

          consistent with regard to the required interest of each co-owner,           
          and not necessarily consistent in terms of the time frame in which          
          ownership is considered.                                                    
               We agree with the appellants. Indeed, MPEP § 1490, which               
          relates to the filing of a terminal disclaimer for the purpose of           
          obviating a double patenting rejection of the obviousness type3,            
          explicity links the meaning of common ownership in a double                 
          patenting context to the definition in MPEP § 706.02(l)(2). In our          
          opinion, this is dispositive of the issue before us.                        
               Accordingly, the double patenting rejection at issue is                
          inappropriate because the Bennett patent and appellants’                    
          application are not “commonly owned” as defined in MPEP                     
          § 706.02(l)(2). Certainly, the examiner has cited no                        
          countervailing authority mandating that a different definition              
          should apply.                                                               
               Since we have found that an obviousness-type double patenting          
          rejection is inappropriate in this case, the associated question of         
          obviousness becomes moot. Nevertheless, we shall consider the               


               3                                                                      
               3 In accordance with 37 CFR § 1.321(c), terminal                       
          disclaimers are ordinarily filed for the purpose of obviating               
          obviousness-type double patenting rejections, and must include a            
          provision conditioning enforceabililty on maintenance of common             
          ownership.                                                                  
                                          6
