          Interference No. 103,345                                                    


                    public disclosure by filing a patent application, we              
                    do not believe that a charge of abandonment,                      
                    suppression or concealment may be sustained against               
                    a senior party where, as here, the charge is based                
                    solely on an unexplained delay between actual                     
                    reduction to practice and filing, and there is no                 
                    evidence either of specific intent or that the                    
                    senior party was spurred into filing his application              
                    by knowledge of the opponent's activities.                        
          Roberge has pointed to no evidence of spurring or specific                  
          intent and therefore has failed to demonstrate that Staples                 
          abandoned, suppressed, or concealed the invention even                      
          assuming the second model amounted to an actual reduction to                
          practice.  Consequently, we need not decide whether, as                     
          Staples contends, that model failed to constitute an actual                 
          reduction to practice because it was not tested in a patient's              
          mouth.                                                                      
                                      Judgment                                        
                    Judgment on the issue of priority is hereby awarded               
          in favor of Staples, who is therefore entitled to a patent                  
          containing his application claims that correspond to the                    
          count, i.e., claims 1-23.  Accordingly, judgment on the issue               
          of priority is hereby entered against Roberge, who is                       
          therefore not                                                               



                                          - 25 -
