          Appeal No. 97-1224                                                          
          Application 08/445,866                                                      



               The appellants’ argument which we find to be dispositive of            
          the issue of enablement is that providing structures for                    
          accomplishing these tasks would have been within the skill of the           
          artisan, without undue experimentation, and therefore the                   
          enablement rejection is not well taken.  The appellants have                
          provided evidence in support of this position in the form of                
          several patents.                                                            
               It is well established case law that the test regarding the            
          enablement requirement of 35 U.S.C. § 112, first paragraph, is              
          whether the disclosure, as filed, is sufficiently complete as to            
          enable one of ordinary skill in the art to make and use the                 
          claimed invention without undue experimentation.  See Atlas                 
          Powder Co. v. E.I. du Pont de Nemours & Co., 750 F.2d 1569, 1576,           
          224 USPQ 409, 413 (Fed. Cir. 1984).  In the present case, we                
          appreciate the examiner’s discomfiture over the lack of infor-              
          mation and illustration regarding the two features to which                 
          objection was taken.  However, we share the appellants’ opinion             
          that the level of skill in this art is such that one of ordinary            
          skill in the art would have been able, without undue experi-                
          mentation, to fashion mechanisms which would permit the blade               



                                          4
