          Appeal No. 94-2232                                                          
          Application 07/888,367                                                      


               [W]e hold that authorship of an article by itself does                 
          not                                                                         
               raise a presumption of inventorship with respect to the                
               subject matter disclosed in the article.  Thus, co-                    
          authors                                                                     
               may not be presumed to be coinventors merely from the                  
          fact                                                                        
               of co-authorship. . . .                                                
                    . . . [When there was] ambiguity created by the                   
               printed publication . . . [i]t was incumbent, therefore,               
          on appellant to provide a satisfactory showing which would                  
          lead                                                                        
               to a reasonable conclusion that he is the sole inventor.               
                    . . . . .                                                         
                    In the declaration, appellant provides the                        
          explanation                                                                 
               that the co-authors of the publication . . . “were                     
          students                                                                    
               working under the direction and supervision of the                     
          inventor       . . . .”  This statement . . . provides a clear              
          alternative                                                                 
               conclusion . . . .  On the record here, the board should               
               not have engaged in further speculation as to whether                  
               appellant’s view was shared by . . . [the] co-authors but              
               rather should have accepted that . . . [the co-authors]                
          were                                                                        
               acting in the capacity indicated, that is, students                    
          working                                                                     
               under the direction and supervision of appellant.  From                
          such                                                                        
               a relationship, joint inventorship cannot be inferred in               
          the                                                                         
               face of sworn statements to the contrary.                              
          In light of Raikhel’s declaration, the examiner erred as a                  
          matter of law in presuming that the co-authorship of the Lee
