                 Application No. 07/983,118                                                                                                             


                 the invention as set forth in claims 34-36, 39-41, and 51 .                                           3                                
                 Accordingly, we reverse.                                                                                                               
                          With respect to the 35 U.S.C. § 112, second paragraph,                                                                        
                 rejection of claims 34-43, 50, and 51, the Examiner initially                                                                          
                 asserts the lack of clarity in the claim language resulting                                                                            
                 from the use of the terminology "pixel" and "window."  In                                                                              
                 apparently finding the words synonymous, the Examiner                                                                                  
                 questions the difference in meaning between "pixel" and                                                                                
                 "window" as used in the claims.  In a related contention, the                                                                          
                 Examiner also asserts the indefiniteness of the language                                                                               
                 "means for opening pre-selected windows" in claim 34.                                                                                  
                         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                                                                            

                          3At page 5 of the Answer, the Examiner has indicated the                                                                      
                 allowability of claims 37, 38, 42, 43, and 50 subject to being                                                                         
                 rewritten to overcome the indefiniteness rejection under the
