HOSHINO et al V. TANAKA - Page 34




          Interference No. 103,208                                                    
          Hoshino et al. v. Tanaka                                                    

          his discretion, on account of this new line of argument, in                 
          determining that Hoshino failed to set forth a prima facie                  
          basis for relief.  In any event, however, Hoshino’s argument                
          is both speculative and presumptuous, and is rejected.                      
               That Tanaka did not specifically describe using the sign               
          of the defocus amount until the second Japanese priority                    
          application and a first order term of the defocus amount until              
          the instant directly involved U.S. application does not                     
          demonstrate something                                                       




          significant regarding the obviousness or unobviousness of                   
          using  the sign of the defocus amount or a first order term                 
          thereof.   In our view, it is without basis for Hoshino to                  
          conclude that the reason Tanaka did not describe a particular               
          embodiment is that the embodiment was not obvious to Tanaka.                
          Tanaka’s first Japanese priority application may not contain a              
          written descrip- tion of Hoshino’s proposed new counts 2, 3,                
          and 4, but it is a long and fanciful stretch from there to                  
          conclude that the lack  of description demonstrates                         
          nonobviousness to Tanaka.                                                   

                                       - 34 -
