         Interference No. 104,290                                                            



         in vitro static sample of explanted tissue, let alone a dynamic                     

         organ. EX-5153, 110. Since the invention has been described as                      
         merely an improvement in a single needle ablation device, it                        
         would seem to be incumbent on the part of the experimenters to                      
         show that multiple electrodes could be accurately and repeatably                    
         deployed at a predesignated location in the target organ.                           

         Furthermore, Hansen states that the ability to deploy the elec                      
         trodes at a designated target is made even more uncertain in that                   
         the tissue in a living patient undergoes movement due to respira                    

         tion, arterial pulsation and peristaltic motion of adjacent                         

         organs. Id. Hence, the simple forcing of the distal end of the                      

         catheter to a random position in the explanted liver, as was                        
         apparently the experimental protocol used here," does not appear                    


               " Apparently, the experiments were undertaken with only a                     
         verbal protocol. LeVeen and Fox agree on this point. LR92;                          
         LR192. Kilzer is of the opinion that some written protocols                         
         existed. LR289-91. Notwithstanding the conclusory sta:tements                       
         of Fox and LeVeen that the experiments were successful, it is                       
         difficult for the junior party to prove the success of any                          
         experiment without evidence of some sort of protocol or criteria                    
         for defining success. Note the following exchange at LR128:                         

         Q Did that [oral] protocol define what was considered a                             
         successful ablation?                                                                
         A In general--in a general sense, as before, large size and                         
         homogeneity was probably a parenthetical desired outcome, but it                    
         was not a criteria. There were no specific criteria. Criteria
