          Appeal No. 95-5030                                                          
          Application 07/815,694                                                      


                    characteristic in any networking system.                          
                    (See. IEEE 802 + standards for LAN's) . . . .                     
                    Such limitations to information regarding                         
                    data [sic, is] in not patentable over IEEE                        
                    standards nor over the prior art of Fava et                       
                    al in view of Miro.                                               

               The appellants disagree that the limitation at issue is a              
          basic characteristic of any networking system and notes that the            
          examiner has not furnished a copy of any IEEE publication or                
          alternative form of evidence relating to IEEE standards to the              
          appellants (Br. at 14-15).  We will not simply take the                     
          examiner's word as sufficient evidentiary support for an                    
          important finding of fact, where the appellants have challenged             
          the examiner's position and discussed examples inconsistent with            
          the examiner's position.  In In re Ahlert, 424 F.2d 1088, 1091,             
          165 USPQ 418, 420 (CCPA 1970), the Federal Circuit has stated:              

                    Assertions of technical facts in areas of                         
                    esoteric technology must always be supported                      
                    by citation to some reference work recognized                     
                    as standard in the pertinent art and the                          
                    appellant given, in the Patent Office, the                        
                    opportunity to challenge the correctness of                       
                    the assertion or the notoriety or repute of                       
                    the cited reference.                                              

               Even though the examiner has referred to IEEE standards as             
          having certain features, no IEEE publication or other IEEE type             
          prior art has been included in the basis of the rejection.  We              
                                          7
