          Appeal No. 1995-2785                                                          
          Application No. 07/576,423                                                    


               The rejection of claims 17 through 19, 21 through 23, 26,                
          and 30 under 35 U.S.C. § 112, first paragraph, as based on a                  
          specification which does not adequately teach how to make or                  
          how to use the claimed invention is reversed.                                 
               Claims 17 through 19, 26, and 30 stand rejected under                    
          35 U.S.C. § 112, second paragraph, as indefinite.  Again, in                  
          view of its brevity, we reproduce the entire statement of                     
          rejection from the Examiner's Answer (Paper No. 24), page 4,                  
          lines 8 through 15:                                                           
               Claims 17-19, 26 and 30 are rejected under                               
               35 U.S.C. § 112, second paragraph, as being                              
               indefinite for failing to particularly point out and                     
               distinctly claim the subject matter which applicant                      
               regards as the invention.  Applicants inclusion of                       
               the language "under conditions that include 6x SSC                       
               at 42E C" fails to adequately specify hybridization                      
               conditions, as such are incomplete; the stringency                       
               of hybridization is dependent upon numerous other                        
               factors, such as the amount of formamide and/or                          
               other chemicals present. Therefore it is not clear                       
               from the claims what the hybridization conditions                        
               are, and therefore what the metes and bounds of the                      
               claims are.                                                              
               The examiner expresses concern that appellants' claim                    
          language "fails to adequately specify hybridization                           
          conditions" and that "it is not clear from the claims what the                
          hybridization conditions are."  However, as stated in Ex parte                
          Jackson,                                                                      
                                          -7-
