              Appeal No. 2002-2154                                                                  Page 4                
              Application No. 09/217,496                                                                                  


              F.2d 760, 772, 218 USPQ 781, 789 (Fed. Cir. 1983), cert. denied, 465 U.S. 1026                              
              (1984).                                                                                                     


                     All the claims under appeal recite in one manner or another the following                            
              limitations: (1) pairs of opposed terminal ends of a rigid members are disposed in facing                   
              relationships on respective adjacent hull sections; (2)  at least one rigid elongated linear                
              shank member;  (3) each said shank member spanning between a pair of facing                                 
              terminal ends  and cooperating therewith to form a releasable rigid, load bearing                           
              coupling between said adjacent sections;  and (4) that cooperation between each                             
              respective shank member and pair of facing terminal ends for all said hull sections                         
              couples said hull sections into a rigid,  load bearing unitary boat.                                        


                     Morgan's invention relates to barges and, more particularly, to barges comprised                     
              of a plurality of a modular float sections, assembled by drawing them together from a                       
              spaced array, and releasably secured one to the other through separable alignment                           
              pins and post tensioning cables.  Figures 1 and 2 show a modular barge 10 which                             
              includes a plurality of floating modules 12 and alignment bodies or pins 14 assembled                       
              in an array and linked by elongated filaments in the form of cables threaded                                
              therethrough.  The modules 12 are watertight structures, each having a generally                            
              rectangular transverse cross-sectional periphery defining a deck surface 18, a bottom
