          Appeal No. 1998-2476                                                        
          Application No. 08/074,485                                                  

          by one possessing the ordinary level of skill in the pertinent              
          art.  Id.                                                                   
               The examiner’s focus during examination of claims for                  
          compliance with the requirement for definiteness of 35 U.S.C.               
          § 112, second paragraph, should be whether the claims meet the              
          threshold requirements of clarity and precision, not whether                
          more suitable language or modes of expression are available.                
          Some latitude in the manner of expression and the aptness of                
          terms is permitted even though the claim language is not as                 
          precise as the examiner might desire.  If the scope of the                  
          invention sought to be patented cannot be determined from the               
          language of the claims with a reasonable degree of certainty,               
          a rejection of the claims under 35 U.S.C. § 112, second                     
          paragraph, is appropriate.                                                  
               We have reviewed the comments and statements of the                    
          examiner and the responses by appellants as outlined above.                 
          Following the guidelines stated above, we conclude that the                 
          examiner is not justified in finding the claims as indefinite.              
          Appellants’ responses to the various points raised by the                   
          examiner are self- explanatory and fully understandable to an               
          artisan.  Therefore, we do not sustain the rejection of claims              

                                          8
