          Appeal No. 95-0543                                                          
          Application 08/008,734                                                      

          ordinary interpretation, it is clear that Potter fully meets the            
          literal recitations of claim 3.                                             
          There is no question that the components of Potter are                      
          bonded to each other by way of a chromium-gold(silver)-                     
          gold(silver)-chromium bond as discussed above.  Potter describes            
          a process of applying pressure and heat to effect a thermal                 
          compression bond.  More specifically, Potter discloses that                 
          “thermal compression bonding is taken to mean a process for                 
          fabricating a robust permanent bond between two metal surfaces,             
          simultaneously using heat and pressure without melting either               
          metal surface” [column 3, lines 35-39, emphasis added].  The                
          application of pressure and heat to bond two metal surfaces                 

          together without melting either metal surface as described by               
          Potter would appear to be the very definition of a “pressure                
          sintered connection.”  Therefore, in our view, Potter clearly               
          discloses such a connection.                                                
          With respect to appellants’ argument that their pressure                    
          sintered connection is different from Potter’s connection, we               
          agree with the examiner that there is no evidence in support of             
          this contention.  We note that claim 3 recites no ranges of                 
          pressure or temperature by which any unusual properties can be
