            Application No. 08/965,180                                                                   


            the molybdenum alloy of Okada to have the composition taught                                 
            by the article in order to increase the hardness and strength                                
            of the frictional surface at elevated temperatures.                                          
                  Claim 5 stands rejected under 35 U.S.C. § 103(a) as                                    
            unpatentable over Okada '451 in view of The Science and                                      
            Technology article and Marin as applied to claims 1 and 4 and                                
            further in view of patent '827 to Okada.  The examiner states                                
            that Okada '827 discloses a cross-hatch pattern on the                                       
            frictional surface 9d.  Therefore, it is the examiner's                                      
            conclusion that it would have been obvious to have constructed                               
            the tiles of Okada '451 to have a cross-hatch pattern as                                     
            taught by Okada '827 in order to reduce abrasion on the guide                                
            rail and eliminate uneven contact.                                                           
                  Claims 6 and 7 stand rejected under 35 U.S.C. § 103(a) as                              
            unpatentable over Okada '451 in view of The Science and                                      
            Technology article and Marin and further in view of Black.                                   
            According to the examiner, Black would have rendered obvious                                 
            at the time the invention was made the placement of tiles in                                 
            Okada '451 via a layer of heat resistant rubber to provide                                   
            high conformability in the elevator safety brake.                                            
                                               OPINION
