               Appeal No. 2006-1085                                                                         
               Application No. 10/392,209                                                                   

               concepts, like those involved in the present application, it is reasonable to                
               permit inquiry into other areas where one of even limited technical skill                    
               would have been aware that similar problems exist.  See In re Heldt,                         
               433 F.2d 808, 812, 167 USPQ 676, 679 (CCPA 1970).                                            


                      As for appellants’ assertion (brief, page 7) that the examiner “did not               
               identify any motivation or suggestion to combined the cited references,” we                  
               direct attention to page 3 of the answer, wherein the examiner has urged that                
               it would have been obvious to one of ordinary skill in the art at the time of                
               appellant’s invention to provide the carts or scooters of Karashima with                     
               flanged connections like those of John “to prevent the scooters from                         
               disconnecting in either the upward or downward directions.”  However, the                    
               real issue on appeal is whether the stated rationale of the examiner would                   
               have been adequate to teach or suggest to one of ordinary skill in the art at                
               the time of appellant’s invention the combination of Karashima and John                      
               urged by the examiner so as to render the subject matter on appeal obvious                   
               within the meaning of 35 U.S.C. § 103.  In this case, we agree with appellant                
               that, absent the hindsight benefit of appellant’s own disclosure and claims,                 




                                                     8
