         Appeal No. 2004-1815                                                       
         Application No. 09/781,582                                Page 21          

         argued, we note, as explained above, that Ness ‘289 reasonably             
         describes the opening size of each compartment as a result                 
         effective variable for dispensing fluid through one opening and            
         dry food through the other via gravity.  It is our view, that one          
         of ordinary skill in the art would have arrived at a size for              
         each opening of Ness “289 that would be encompassed by the claim           
         language upon routine experimentation.  After all skill, and not           
         the converse, is presumed on the part of those practicing in the           
         art.  See In re Sovish, 769 F.2d 738, 743, 226 USPQ 771, 774               
         (Fed. Cir. 1985); In re Jacoby, 309 F.2d 513, 516, 135 USPQ 317,           
         319 (CCPA 1962).  Thus, we shall affirm the examiner’s § 103(a)            
         rejection of claims 35-37, 50 and 51 over Ness ‘289 on this                
         record.                                                                    

                                     CONCLUSION                                     
              The decision of the examiner to reject claims 35-37, 50 and           
         51 under 35 U.S.C. § 103(a) over Ness ‘289 is affirmed.  The               
         decision of the examiner to reject claims 1, 4-9, 13, 16, 47 and           
         48 under 35 U.S.C. § 102(b) as being anticipated by Stegath; to            
         reject claims 1-12, 16, 17, 19 and 48 under 35 U.S.C. § 102(b) as          
         being anticipated by Ness ‘561; to reject claims 1-9, 16-18, 47            
         and 48 under 35 U.S.C. § 102(b) as being anticipated by Ness
