          Appeal No. 2003-0663                                                        
          Application No. 09/072,549                                                  

          sent out via port 845 and Audio/Video I/O port 805 onto AV                  
          Network 901.  Appellants contend that these teachings show that             
          the transmission of TV-quality video over UTP is accomplished by            
          this video communications system having an Audio/Video (A/V)                
          transceiver as shown in Figure 19.                                          
               It appears to us that appellants have given a reasonable               
          explanation as to how the TV-quality transmission is accomplished           
          while the examiner merely asserts that the specification merely             
          recites a desire to have “TV-quality” video without an adequate             
          disclosure as to how to accomplish this.  On balance, it does not           
          appear to us that the examiner has made a reasonable finding to             
          doubt the objective truth of appellants’ statements as to how TV-           
          quality transmission is effected.  Since we find no sufficient              
          reason to doubt appellants’ disclosure and statements, as well as           
          the statements in the Ludwig declaration, we will not sustain the           
          rejection of claims 1-5, 7-11, 21-25 and 27-31 under 35 U.S.C.              
          § 112, first paragraph.                                                     
               When a rejection is made on the basis that the disclosure              
          lacks enablement, it is incumbent upon the examiner to explain              
          why he/she doubts the truth or accuracy of any statement in a               
          supporting disclosure and to back up assertions with acceptable             
          evidence or reasoning which is inconsistent with the contested              
                                         -6–
