          Interference No. 103,146                                                    



                    difficult to establish "subjective good                           
                    faith"                                                            

                    sufficient to prevent the drawing of an                           
                    inference of intent to mislead.  A mere                           
                    denial of intent to mislead (which would                          
                    defeat every effort to establish                                  
                    inequitable conduct) will not suffice in                          
                    such circum- stances.  LaBounty Mfg. Inc.                         
                    v. U.S. Int'l Trade Comm'n, 958 F.2d 1066,                        
                    1076, 22 USPQ2d 1025, 1033 (Fed. Cir.                             
                    1992), quoting FMC Corp., 835 F.2d at 1416,                       
                    5 USPQ2d at 1116.                                                 


                                     Public Use                                       
                    Barker has included arguments in his brief                        
          respecting public use of the invention during the Shore field               
          visits.  Barker Brief at 66-67.  However, the junior party can              
          point to                                                                    
          no specific evidence that the device was used during the field              
          visits.  Shore’s memo does not state that the device was used,              
          and Shore’s testimony is that it was not used.  ER10, ¶9.  We               
          categorically reject Barker’s argument that a public use                    
          occurred and that an inequitable conduct holding could be                   
          based properly thereon.
