          Appeal No. 1998-1435                                       Page 9           
          Application No. 08/132,584                                                  


               We begin by finding that the references represent the                  
          level of ordinary skill in the art.  See In re GPAC Inc., 57                
          F.3d 1573, 1579, 35 USPQ2d 1116, 1121 (Fed. Cir. 1995)                      
          (finding that the Board of Patent Appeals and Interference did              
          not err in concluding that the level of ordinary skill was                  
          best determined by the references of record); In re Oelrich,                
          579 F.2d 86, 91, 198 USPQ 210, 214 (CCPA 1978) ("[T]he PTO                  
          usually must evaluate ... the level of ordinary skill solely                
          on the cold words of the literature.").  Of course, “‘[e]very               
          patent application and reference relies to some extent upon                 
          knowledge of persons skilled in the art to complement that                  
          [which is] disclosed ....’”  In re Bode, 550 F.2d 656, 660,                 
          193 USPQ 12, 16 (CCPA 1977) (quoting In re Wiggins, 488 F.2d                
          538, 543, 179 USPQ 421, 424 (CCPA 1973)).  Those persons “must              
          be presumed to know something” about the art “apart from what               
          the references disclose.”  In re Jacoby, 309 F.2d 513, 516,                 
          135 USPQ 317, 319 (CCPA 1962).                                              


               We next note that when the appeal brief was filed, 37                  
          C.F.R. § 1.192(c)(7)(1996) included the following provisions.
