ALTHAUS V. OLDROYD - Page 15




          Interference No. 104,158                                                    



          and well above the surface to be shaved in the other two                    
          embodiments.  To extrapolate such a disclosure into a teaching              
          of an                                                                       
          axis on or below the surface being shaved is not supported by               
          the teachings of Kirk.  As we stated previously, it is based                
          on mere speculation or conjecture.                                          
                    For the reasons above, Althaus has not sustained his              
          burden of showing claims 9-28 of Oldroyd are unpatentable                   
          under 35 U.S.C. § 103.                                                      


          Althaus Claim 7                                                             
                    We turn to the issue of whether Althaus has                       
          established that claim 7 of the Althaus patent should be                    
          designated as not corresponding to the count in interference.               
          The test we must apply is found in 37 CFR § 1.601(n).  The                  
          rule reads as follows:                                                      
                    Invention (A) is the same patentable                              
                    invention as an invention "B" when                                
                    invention "A"                                                     

                    is the same as (35 U.S.C. 102) or is                              
                    obvious (35 U.S.C. 103) in view of                                
                    invention "B" assuming invention "B" is                           

                                          15
