          Application No. 08/821,978                                                  


          available alternatives provided in the gaming machine is                    
          required.  Claim 34 is ambiguous as to whether the step of                  
          exposing implicitly requires selection between two available                
          alternatives (related or unrelated) or merely recites a genus               
          including two species (related and unrelated).  Reading claim 34            
          in light of the circumstances discussed above with regard to the            
          other independent claims and in light of appellants' arguments on           
          pages 16-21 of the brief6, we are unable to resolve this                    
          ambiguity with any certainty.                                               
               For the foregoing reasons, we conclude that independent                
          claims 10, 17, 27 and 34, as well as claims 11-16, 18-26, 28-33             
          and 35-46 which depend therefrom, are indefinite.                           
                                     CONCLUSION                                       
               To summarize, the examiner’s rejection of claims 10, 17 and            
          18 under the second paragraph of 35 U.S.C. § 112, second                    
          paragraph, is sustained and denominated a new ground of rejection           
          pursuant to 37 CFR § 1.196(b).  Additionally, a new rejection of            





               6 In this regard, we note that, in the event that appellants' claims are
          amended to remove the above-noted ambiguity so as to be of a scope consistent
          with the arguments on pages 16-21 of appellants' brief, such claims would not
          appear to be supported by appellants' original disclosure.  Accordingly, under
          such circumstances, the examiner may wish to consider the appropriateness of a
          written description requirement under 35 U.S.C. § 112, first paragraph.
