DIONNE et al v. LIOTTA et al - Page 6




          Interference No. 103,906                                                      


          Cortright is viewed by us as being consistent with a broad                    
          construction of Dionne’s claims here, Dionne’s arguments to the               
          contrary notwithstanding.                                                     
               Other cases relied upon by Dionne are also deemed to be                  
          consistent with our broad claim interpretation.  For instance, in             
          North Am. Vaccine, Inc. v. American Cyanamid Co., 7 F.3d 1571,                
          1575-76, 28 USPQ2d 1333, 1336 (Fed. Cir. 1993), the claim                     
          expression “a terminal portion” was construed to have its normal              
          meaning.  Here, we also are ascribing a normal meaning to the                 
          phrase “a viral infection” as in effect referring to any viral                
          source of mammalian infection.  Here, unlike in North Am.                     
          Vaccine, Inc., the issue is the scope of the word “viral.”                    
               More to the point is In re Wright, 999 F.2d 1557, 1559 and               
          1561, 27 USPQ2d 1510, 1511 and 1513 (Fed. Cir. 1993).  In Wright,             
          the claim term “a pathogenic RNA virus” was interpreted to                    
          embrace any and all pathogenic RNA viruses.                                   
               Having made these initial observations, we now proceed with              
          a more detailed discussion.                                                   
                                 I. Claim Construction                                  
               As highlighted above, we agree with Liotta that the scope of             
          Dionne’s claims broadly encompasses the treatment of any viral                
          infection in a mammal.                                                        

                                           6
