STEVENS v. MILLER - Page 5




          Interference No. 103,611                                                    


               The junior party Stevens does not contend that it actually             
          reduced to practice the invention of the count prior to its                 
          filing date.  In order to prevail herein as the prior inventor,             
          Stevens submits that it conceived the invention of the count as             
          early as January 8, 1993 and was reasonably diligent from this              
          date to its constructive reduction to practice on August 3, 1993.           
               As between the parties, Miller asserts the earlier date of             
          conception, as early as April 20, 1988.  Miller will be entitled            
          to prevail herein as first to conceive and first to reduce to               
          practice (its May 25, 1993 filing date is a constructive                    
          reduction to practice) if it has established a date of conception           
          prior to the January 8, 1993 date of conception alleged by                  
          Stevens.                                                                    
                                                                                     
          Count Ambiguity                                                             
               The count is the measure of the invention.  Such being the             
          case, we will address the position of Stevens that the count is             
          ambiguous before proceeding to decide the issue of prior                    
          conception by Miller.                                                       
               The count is identical to claim 1 in the Stevens                       
          application.  Based upon alleged different interpretations of the           
          count presented by Miller and Stevens, the junior party contends            
          that the count is ambiguous and should be interpreted in light of           
          Stevens’ specification from which it originated.                            

                                          5
