              Appeal 2007-0691                                                                     
              Application 10/465,423                                                               
          1   and (c).  In addition, Ciba attempts to limit the definition of (a) and (c) by       
          2   specifying that a lubricant comprising components (a) and (c), but without           
          3   component (b), produces a lead content which exceeds 100 ppm when                    
          4   measured according to ASTM D 6594.  The claim makes no attempt to                    
          5   define the lead content of a lubricant comprising components (a), (b) and (c)        
          6   when measured according to ASTM D 6594.  The claim reads on                          
          7   compositions where the lead content of the claimed composition with                  
          8   component (b) present could exceed the lead content when component (b) is            
          9   not present when measured according to ASTM D 6594.                                  
         10         Method claim 12 is similar.  The only method step recited in claim 12          
         11   is "incorporating" into a composition comprising (a) and (c) a further               
         12   component (b).  At no point in the claimed process is there a requirement            
         13   that the composition comprising components (a), (b) and (c) come into                
         14   contact with lead.  It is difficult to see how a method of preventing corrosion      
         15   can take place by merely adding component (b) to a mixture of components             
         16   (a) and (c) and there is no contact with any lead source required.                   
         17                                                                                        
         18                   Weight to be given the experimental data                             
         19         The Examiner declined to give the experimental data much weight                
         20   finding that it is not commensurate in scope with the breadth of the claims.         
         21   Answer 5.                                                                            
         22         The Examiner expressed a concern that a showing based on one                   
         23   triazole and one sulfur-containing compound does not justify a finding that          
         24   the same triazole would achieve the lead-lowering properties with other              
         25   sulfur-containing compounds.  Answer 5.  In other words, the Examiner                
         26   raised the reasonable question of whether lead-lowering properties are solely        

                                                13
