               Appeal 2007-4316                                                                            
               Application 09/911,268                                                                      
               28. Moreover, the Examiner points out that the Eckel declaration did not                    
               show that the Eckel 930 D.1 phosphorus compound contained less                              
               than 1 w% IPP.  (Id.)                                                                       

               C. Discussion                                                                               
                      "A claim is anticipated if each and every limitation is found either                 
               expressly or inherently in a single prior art reference."  Bristol-Myers Squibb             
               Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1374, 58 USPQ2d 1508, 1512                     
               (Fed. Cir. 2001).  "In general, a limitation or the entire invention is inherent            
               and in the public domain if it is the 'natural result flowing from' the explicit            
               disclosure of the prior art."  Schering Corp. v. Geneva Pharm., Inc., 339                   
               F.3d 1373, 1379 (Fed. Cir. 2003).                                                           
                      “[W]hen the PTO shows sound basis for believing that the products of                 
               the applicant and the prior art are the same, the applicant has the burden of               
               showing that they are not.”  In re Spada, 911 F.2d 705, 708, 15 USPQ2d                      
               1655, 1658 (Fed. Cir. 1990).  Our reviewing court has long accepted the                     
               practice of making rejections under § 102 or § 103 in the alternative as long               
               as the applicant is fully apprised of the grounds of rejection.  Id. at 708 n.2,            
               15 USPQ2d at 1658 n.2.                                                                      
                      Obviousness is a legal conclusion based on underlying findings of                    
               fact.  In re Gartside, 203 F.3d 1305, 1316, 53 USPQ2d 1769, 1778 (Fed.                      
               Cir. 2000).  It follows that if a limitation of a claim is neither met nor                  
               suggested by the prior art, the conclusion of obviousness cannot stand.                     
                      Applicants have chosen to attack only the critical part of the                       
               Examiner's rejections, i.e., the Examiner's findings that the disclosures of a
