          Appeal No. 1998-2884                                                        
          Application No. 08/495,960                                                  


          limitations."  Wertheim, 541 F.2d at 262, 191 USPQ at 96                    
          citing In re Smythe, 480 F.2d 1376, 1382, 178 USPQ 279, 284                 
          (CCPA 1973).                                                                
               In view of the above discussion, it is our conclusion                  
          that, under the factual situation presented in the present                  
          case, the statutory written description requirement has been                
          satisfied because Appellant was clearly in possession of the                
          invention at the time of filing of the application.                         
          Therefore, we do not sustain the rejection of claims 13-19 and              
          21 under the first paragraph of 35 U.S.C. § 112.                            
               Turning to a consideration of the 35 U.S.C. § 112, second              
          paragraph, rejection of claims 13-19 and 21, we note that the               
          general rule is that a claim must set out and circumscribe a                
          particular area with a reasonable degree of precision and                   
          particularity when read in light of the disclosure as it would              
          be by the artisan.  In re Moore, 439 F.2d 1232, 1235, 169 USPQ              
          236, 238 (CCPA 1971).  Acceptability of the claim language                  
          depends on whether one of ordinary skill in the art would                   
          understand what is claimed in light of the specification.                   
          Seattle Box Co. v. Industrial Crating & Packing, Inc., 731                  
          F.2d 818, 826, 221 USPQ 568, 574 (Fed. Cir. 1984).                          
                                          9
