              Appeal No. 1999-1162                                                                                       
              Application No. 08/427,837                                                                                 



                     Rather than reiterate the conflicting viewpoints advanced by the examiner and the                   
              appellants regarding the noted rejections, we make reference to the Examiner's Answer                      
              (Paper No. 14, September 12, 1997) for the examiner's complete reasoning in support of                     
              the rejection, and to the appellants’ Brief  (Paper No. 13, July 10, 1997) for the appellants’             
              arguments thereagainst.  As a consequence of our review, we make the determinations                        
              which follow.                                                                                              
              Claim Interpretation                                                                                       
                     Our appellate reviewing court stated in Panduit Corp. v. Dennison Mfg. Co.,                         
              810 F.2d 1561, 1567-1568, 1 USPQ2d 1593, 1597 (Fed. Cir.), cert denied, 481 U.S.                           
              1052 (1987):                                                                                               
                            Analysis begins with a key legal question -- what is the                                     
                            invention claimed?  Courts are required to view the claimed                                  
                            invention as a whole.  35 U.S.C. § 103.  Claim interpretation,                               
                            in light of the specification, claim language, other claims and                              
                            prosecution history, is a matter of law and will normally control                            
                            the remainder of the decisional process.  [Footnote omitted.]                                

              To that end, we also note that during ex parte prosecution, claims are to be given their                   
              broadest reasonable interpretation consistent with the description of the invention in the                 
              specification.  In re Zletz, 893 F.2d 319, 321, 13 USPQ2d 1320, 1322 (Fed. Cir. 1989).                     
                     The term “highly immunogenic” found in claim 9 is not defined,  per se, in the                      
              specification.   The examples in the specification do not provide a quantitative value                     

                                                           3
