          Appeal No. 2001-2681                                                        
          Application No. 09/167,295                                                  


               60a).  The examiner explains (answer, pages 12 through                 
               20) that the term “interface” when broadly defined does                
               not necessarily require two separate bodies but could be               
               a thermal “interface” separating different temperature                 
               regions in holding pad 60.  We agree with the examiner’s               
               reasoning that the term “interface” does not necessarily               
               require two different bodies.  Nothing in claim 1 on                   
               appeal precludes the reading of a “second thermal                      
               interface” on different thermal regions that reside in                 
               the unitary holding pad 60.                                            
               Appellants now argue (request, page 4) that “the term                  
          interface, given its broadest reasonable interpretation, requires           
          two or more separate bodies.”  We disagree.  The reading of a claim         
          in light of the specification to interpret broadly worded                   
          limitations explicitly recited in the claim is a quite different            
          thing from reading limitations of the specification into a claim to         
          thereby narrow the scope of the claim by implicitly adding                  
          disclosed limitations which have no express basis in the claim.  In         
          re Prater, 415 F.2d 1393, 162 USPQ 541 (CCPA 1969).  Thus, we still         
          maintain that a second thermal interface1 can be the different              
          thermal regions that lie within the unitary holding pad 60.                 
               Appellants’ request has been granted to the extent that our            
          decision has been reconsidered, but such request is denied with             
          respect to making any modifications to the decision.                        


               1 As the attached definition indicates, an “interface” can             
          be an area in a material where regions meet.
