          Appeal No. 1999-2449                                                        
          Application No. 08/745,584                                 Page 4           

          by the examiner, and the evidence of anticipation and obviousness           
          relied upon by the examiner as support for the rejections.  We              
          have, likewise, reviewed and taken into consideration, in                   
          reaching our decision, appellants' arguments set forth in the               
          briefs along with the examiner's rationale in support of the                
          rejections and arguments in rebuttal set forth in the examiner's            
          answer.  Upon consideration of the record before us, we reverse.            
               We begin with the rejection of claims 1, 2, 5-9, 15, and 16            
          under 35 U.S.C. § 102(b) as anticipated by Gonzales.  To                    
          anticipate a claim, a prior art reference must disclose every               
          limitation of the claimed invention, either explicitly or                   
          inherently.  In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d                
          1429, 1431 (Fed. Cir. 1997).  As stated in In re Oelrich, 666               
          F.2d 578, 581, 212 USPQ 323, 326 (CCPA 1981) (quoting Hansgirg v.           
          Kemmer, 102 F.2d 212, 214, 40 USPQ 665, 667 (CCPA 1939))                    
          (internal citations omitted):                                               
               Inherency, however, may not be established by probabilities            
               or possibilities.  The mere fact that a certain thing may              
               result from a given set of circumstances is not sufficient.            
               If, however, the disclosure is sufficient to show that the             
               natural result flowing from the operation as taught would              
               result in the performance of the questioned function, it               
               seems to be well settled that the disclosure should be                 
               regarded as sufficient.
