          Appeal No. 1996-0427                                                        
          Application 08/210,224                                                      



          pulses, said pulses increasing in length monotonically during               
          said sequence."   On page 9 of the brief, Appellants argue                  
          that this claim language is definite when read in light of the              
          specification on pages 9, 10 and 13 and in light of the struc-              
          ture shown in Figure 5.                                                     
                    Analysis of 35 U.S.C. § 112, second paragraph,                    
          should begin with the determination of whether claims set out               
          and circumscribe the particular area with a reasonable degree               
          of precision and particularity; it is here where definiteness               
          of the language must be analyzed, not in a vacuum, but always               
          in light of teachings of the disclosure as it would be inter-               
          preted by one possessing ordinary skill in the art.  In re                  
          Johnson, 558 F.2d 1008, 1015, 194 USPQ 187, 193 (CCPA 1977),                
          citing In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236, 238                  
          (1971).  Furthermore, our reviewing court points out that a                 
          claim which is of such breadth that it reads on subject matter              
          disclosed in the prior art is rejected under 35 U.S.C. § 102                
          rather than under 35 U.S.C. § 112,
