              Appeal No. 2004-1573                                                                Page 5                
              Application No. 09/494,780                                                                                


              Cir. 1987).  In answering the question, "[t]he Patent and Trademark Office (PTO) must                     
              consider all claim limitations when determining patentability of an invention over the                    
              prior art."  In re Lowry, 32 F.3d 1579, 1582, 32 USPQ2d 1031, 1034 (Fed. Cir. 1994)                       
              (citing In re Gulack, 703 F.2d 1381, 1385, 217 USPQ 401, 403-04 (Fed. Cir. 1983)).                        
                     Here, independent claim 1 recites in pertinent part the following limitations:                     
              "utilizing for at least two of the data channels of the connection one common training                    
              sequence. . . ."  Similarly, independent claim 11 recites in pertinent part the following                 
              limitations: "a signal processor using for at least two of the data channels of the                       
              connection one common training sequence. . . ."  Considering these limitations, claims 1                  
              and 11 require using a single training sequence for at least two of the data channels of                  
              a radio communication connection.                                                                         


                                           2. ANTICIPATION DETERMINATION                                                
                     "Having construed the claim limitations at issue, we now compare the claims to                     
              the prior art to determine if the prior art anticipates those claims."  In re Cruciferous                 
              Sprout Litig., 301 F.3d 1343, 1349, 64 USPQ2d 1202, 1206 (Fed. Cir. 2002).  "A claim                      
              is anticipated only if each and every element as set forth in the claim is found, either                  
              expressly or inherently described, in a single prior art reference."  Verdegaal Bros., Inc.               
              v. Union Oil Co., 814 F.2d 628, 631, 2 USPQ2d 1051, 1053 (Fed. Cir. 1987) (citing                         
              Structural Rubber Prods. Co. v. Park Rubber Co., 749 F.2d 707, 715, 223 USPQ 1264,
