Appeal No. 2000-1737 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.
