          Appeal No. 2004-0415                                                        
          Application No. 09/764,743                                                  


          admittedly old shopping cart, wherein improvement is said to                
          include the implementation of:                                              
                    [A] spring urged brake mechanism capable of                       
               selectively impinging against said rear wheels in order                
               to provide a braking force; and                                        
                    [M]eans for releasing said impinging when two                     
               respective shopping carts are nested together.                         
               The dispositive question is, therefore, whether one of                 
          ordinary skill in the art would have been led to employ the above           
          improvement in the old shopping cart.  On this record, we answer            
          this question in the affirmative.                                           
               As is apparent from this record, the appellants do not                 
          dispute the examiner’s finding1 that:                                       
                    Trimble teaches a conventional shopping cart comprising           
               front and rear wheels, a basket with an upper rim (Figure 1)           
               and a spring (60) urged brake mechanism capable of                     
               selectively impinging against the rear wheels (Figure 1) in            
               order to provide a braking force, and                                  
                    means for releasing said impinging when two respective            
               shopping carts are nested (lines 18-21 of column 6).                   
          In other words, the appellants do not dispute that Trimble                  
          teaches the claimed improvement, i.e., the claimed spring urged             
          brake mechanism and releasing means.  See also Trimble, column 5,           
          lines 10-62 and column 6, lines 7-25.  According to Trimble                 

               1 Compare the Answer, page 3, with the Brief in its                    
          entirety.                                                                   
                                          5
