          Appeal No. 2001-1440                                                        
          Application 08/931,635                                                      

          360, 364 (CCPA 1962).  We therefore reverse the rejection of                
          claim 7.                                                                    
                              Rejection of claims 27-33                               
               The appellant states that claims 27-33 stand or fall                   
          together (brief, page 5).  We therefore limit our discussion of             
          the rejection of claims 27-33 to one claim in this group, i.e.,             
          claim 27.  See In re Ochiai, 71 F.3d 1565, 1566 n.2, 37 USPQ2d              
          1127, 1129 n.2 (Fed. Cir. 1995); 37 CFR § 1.192(c)(7)(1997).                
               In Hermann’s example II, 21.8 g KCl are reacted with 16.5 g            
          Li2SO4 at 25ēC in 100 ml n-butanol saturated with water, and                
          solids are removed from the solution.  At 25ēC the solubility of            
          water in n-butanol is 20.5 wt%.1  Hence, the n-butanol contains             
          16.6 g or 0.92 moles water.  Based upon complete reaction of the            
          Li2SO4 to LiCl, the product contains 0.30 moles LiCl.  The molar            
          ratio of water to LiCl, therefore, is 3, which falls within the             
          scope of the appellant’s claim 27.2  Hermann’s example II,                  
          therefore, at least would have fairly suggested, to one of                  
          ordinary skill in the art, water/LiCl molar ratios within the               

               1 21 Kirk-Othmer Encyclo. Chem. Tech. 378-79 (John Wiley &             
          Sons, 3rd ed. 1983).  A copy of this reference is provided to the           
          appellant with this decision.                                               
               2 This ratio would be higher for incomplete reaction of                
          Li2SO4 to LiCl.                                                             
                                          6
