CHIRIKJIAN et al v. HAN et al v. LEE - Page 14




          fairly placed at issue in the [interference] proceeding, it will           
          be determined [by the board]."  Id.  In dicta, the Federal                 
          Circuit further stated that "[t]he word 'may' in § 135(a)                  
          accommodates the situation when patentability is not placed at             
          issue during the priority contest, but it would contradict the             
          remedial purpose of the legislation if the Board could refuse to           
          decide questions of patentability for which there had been                 
          adduced an appropriate record."  Id.                                       
               The facts in this case differ in significant respects from            
          the facts in Perkins.  To be sure, a similarity is that the issue          
          of whether Han timely presented claims within the meaning of               
          35 U.S.C. § 135(b) can be said to have been "fairly raised"                
          within the meaning of Perkins.  Livak filed a preliminary motion           
          raising a patentability issue, Han opposed and Livak replied;              
          evidence was presented.                                                    
               A significant difference, however, is that here there is no           
          interference-in-fact.  In Perkins, on the other hand, patentee             
          Perkins and applicant Kwon were claiming, and had an interest in,          
          what had been determined to be the same patentable invention, a            
          matter never questioned in the interference by either Perkins or           
          Kwon.  Thus, while there was an interference-in-fact in Perkins,           
          it turned out the invention was not patentable to either party.            
               In this interference, it has been determined inter partes             
          that the parties are not claiming the same patentable invention.           
          An interference is no longer needed because, given the 3-judge             
          motions panel's determination with respect to Livak Preliminary            

                                       - 14 -
