                 Application No. 07/642,417                                                                                                             
                          Appellant argues inter alia that the claims on appeal                                                                         
                 recite either a combination of steps (Brief, page 13), or two                                                                          
                 means (Brief, page 18).  We agree with the appellant’s                                                                                 
                 argument that the claims on appeal are not single means                                                                                
                 claims.  Each of the apparatus claims includes a means for                                                                             
                 changing at least one of the characteristic parameters of the                                                                          
                 noted field, and a means for making the change within a                                                                                
                 specified time interval.  Each of the method claims includes                                                                           
                 two steps that perform the functions of the two means.                                                                                 
                          In summary, the examiner has not presented a sound basis                                                                      
                 for rejecting the claims under the second paragraph of 35                                                                              
                 U.S.C.                                                                                                                                 
                 § 112 .  1                                                                                                                             












                          1In In re Hyatt, 708 F.2d 712, 714, 218 USPQ 195, 197                                                                         
                 (Fed. Cir. 1983), the Court intimated that a single means                                                                              
                 claim should be rejected under the first paragraph of 35                                                                               
                 U.S.C. § 112, and not the second paragraph of 35 U.S.C. § 112.                                                                         
                                                                           3
