          Appeal No. 96-3130                                                          
          Application 08/225,653                                                      


               Under the provisions of 37 CFR § 1.196(b) we make the                  
          following new rejection.                                                    
               Claim 2 is rejected under 35 U.S.C. § 112, second paragraph,           
          for failing to particularly point out and distinctly claim the              
          subject matter that the appellants regard as the invention.   For           
          the reasons stated above with respect to the § 102(e) rejection             
          of claim 2, considerable speculations and assumptions would be              
          necessary in order to in fact determine what structure the                  
          appellants intended to be encompassed by the means-plus-function            
          clause and, therefore, the appellants have failed to set forth              
          the claimed invention with the requisite precision and                      
          particularity.  As our reviewing court stated in In re Donaldson,           
          16 F.3d at 1195, 29 USPQ2d at 1850:                                         

                    Although paragraph six statutorily provides                       
                    that one may use means-plus-function language                     
                    in a claim, one is still subject to the                           
                    requirement that a claim "particularly point                      
                    out and distinctly claim" the invention.                          
                    Therefore, if one employs means-plus-function                     
                    language in a claim, one must set forth in                        
                    the specification an adequate disclosure                          
                    showing what is meant by that language.  If                       
                    an applicant fails to set forth an adequate                       
                    disclosure, the applicant has in effect                           
                    failed to particularly point out and                              
                    distinctly claim the invention as required by                     
                    the second paragraph of section 112.                              


                                          15
