          Appeal No. 98-0584                                                          
          Application 08/238,948                                                      


          lengthy list (including those not specifically mentioned                    
          below), we will not support the examiner's position.                        
               The legal standard for indefiniteness is whether a claim               
          reasonably apprises those of skill in the art of its scope.                 
          In re Warmerdam, 33 F.3d 1354, 1361, 31 USPQ2d 1754, 1759                   
          (Fed.                                                                       


          Cir. 1994).  A degree of reasonableness is necessary.  As the               
          court stated in In re Moore, 439 F.2d 1232, 1235, 169 USPQ                  
          236, 238 (CCPA 1971), the determination of whether the claims               
          of an application satisfy the requirements of the second                    
          paragraph of  § 112 is                                                      
                    merely to determine whether the claims do,                        
                    in fact, set out and circumscribe a                               
                    particular area with a reasonable degree of                       
                    precision and particularity.  It is here                          
                    where the definiteness of language employed                       
                    must be analyzed -- not in a vacuum, but                          
                    always in light of the teachings of the                           
                    prior art and of the particular application                       
                    disclosure as it would be interpreted by                          
                    one possessing the ordinary level of skill                        
                    in the pertinent art. [Emphasis added;                            
                    footnote omitted.]                                                
          In other words, there is only one basic ground for rejecting a              
          claim under the second paragraph of § 112 as being indefinite,              

                                          4
