          Appeal No. 1997-0461                                                         
          Application 08/267,683                                                       

          the disclosures is that Fujii (A1) describes an aqueous                      
          lubricant comprising a metallic soap, a solid lubricant, a                   
          surfactant for dispersing the soap and solid lubricant and                   
          water (page 3, lines 11 through 13).  The solid lubricant may                
          be molybdenum disulfide (page 3, lines 27 and 28). The                       
          surfactant utilized may itself be an anionic type such as a                  
          fatty acid salt (page 3, lines 39 through 41).  As an optional               
          ingredient, the lubricant may also contain a colloidal                       
          titanium pigment in an amount of from 10 to 5000 ppm to                      
          improve the lubricating and rust-preventing effects of the                   
          lubricant (page 3, line 52 through page 4, line 13).                         
               Thus, Fujii (A1) "describes", in the sense of 35 U.S.C.                
          102, a lubricant as claimed in claim 23.  That is, Fujii (A1)                
          describes a lubricant consisting essentially of molybdenum                   
          disulfide powder and "a liquid in which the molybdenum                       
          disulfide powder is dispersed to form a liquid suspension."                  
          Again, we observe that "anticipation" is the ultimate evidence               
          of obviousness.                                                              


               In reaching the above conclusions, we have not overlooked               
          appellant's argument concerning the scope of claim 23 as                     

                                          6
