          Interference 102,760                                                        
          07/695,325 must be unpatentable under 35 U.S.C. § 102(f)                    
          because one of the joint inventors, Rosekind, only contributed              
          experimentation to reduce an embodiment within the scope of                 
          the claimed invention to practice, because Pro-Mold & Tool Co.              
          v. Great Lakes Plastics, Inc., 75 F.3d at 1575, 37 USPQ2d at                
          1632, states, “To be a joint inventor, one must contribute to               
          the conception of an invention.”  Where, as here,                           
          unpatentability of a claimed invention under                                
          35 U.S.C. § 102(f) is at issue, we interpret the above-quoted               
          statement in Pro-Mold & Tool Co. to mean that each of the                   
          joint inventors must contribute to conception of a patentable               
          invention claimed.                                                          
               Conception alone may constitute a patentable invention if              
          the invention conceived satisfies 35 U.S.C. § 112.  However,                
          “one need not necessarily meet the enablement standard of 35                
          U.S.C.                                                                      
          § 112 to prove conception.”  Burroughs Wellcome Co. v. Barr                 
          Lab., Inc., 40 F.3d 1223, 1231, 32 USPQ2d 1915, 1922 (Fed.                  
          Cir. 1994).  Accordingly, while Dement’s conception of an                   
          invention encompassed by the interference count may be                      
          sufficient to establish priority as to the invention defined                
          by an interference count, Rapoport has not shown that Dement’s
