              Interference No. 103,635                                                                                     
              761, 28 USPQ at 385.  Accordingly, we are left only with the "pressure" to file. That alone                  
              does not establish attorney diligence.                                                                       




              "The standards for finding reasonable diligence are harsh. The public policy favors                          
              early disclosure, Honeywell Inc. v. Diamond, Commissioner of Patents and Trademarks,                         
              208 USPQ 452  (D.D.C. 1980); Young v. Dworkin, 489 F.2d 1277, 1279-81, 180 USPQ                              
              388, 390-392 (C.C.P.A. 1974), and thus the law is reluctant to displace an inventor who                      
              was the first to disclose to the public his invention, Naber v. Cricchi, 567 F.2d 382, 385-86                
              & n.5, 196 USPQ 294 , 296-298 & n.5 (C.C.P.A. 1977), cert. denied, 439 U.S. 829, 200                         
              USPQ 64  (1978)."  Liang v. Borger, 214 USPQ 368,       372-373 (Bd. Pat. Int. 1981).                        
              After careful review of the facts in this case, we conclude that only activities directly solely             
              to the exploitation of the invention were conducted in the U.S.  and, as such, are not directly              
              related to reduction to practice of the subject matter of the count.  Accordingly, we find that              
              Scott has not met its burden of establishing reasonable diligence from a point just prior to                 
              Koyama's entry into the field (i.e., March 13, 1990) until Scott's constructive reduction to                 
              practice (i.e., March 29, 1990).                                                                             
              Prior Conception With Reasonable Diligence Up To Actual Reduction to Practice                                
                     In the second line of argument, Scott contends that they have demonstrated prior                      
              conception with reasonable diligence from just before Koyama's entry into the field (i.e.,                   
              March 13, 1990) up to actual reduction to practice.                                                          

                                                                                                                           
              of the instant invention." Burns v. Curtis, 172 F.2d 588, 591, 80 USPQ 587, 589 (CCPA 1949).                 
                                                            14
