Appeal No. 95-3484 Application 08/098,236 identical or substantial identical and that, consequently, appellants had the burden of providing competent objective evidence to the contrary (decision, pages 3-4). The board found the evidence relied upon by appellants to be deficient and affirmed the rejection (decision, pages 4-7). Appellants subsequently narrowed the recited range of the ethylene content of the copolymer to 40-60 mol%, which is outside the range disclosed by Biswell. The examiner now rejects the claims over Stearns in view of Biswell, and the issue of the propriety of the examiner’s rejection over this combination of references is before us in the present appeal. We have carefully considered all of the arguments advanced by appellants and the examiner and agree with appellants that the examiner’s rejection is not well founded. Accordingly, we do not sustain this rejection. Stearns discloses an ethylene-propylene copolymer having an ethylene content of 29-71 mol%, preferably about 40-60 mol%, and a number average molecular weight of 300-4000 (col. 1, line 68 - col. 2, line 1; col. 3, lines 50-52; col. 5, lines 13-16; col. 6, lines 55-57; col. 10, lines 6-10), which is useful as a lubricating oil (col. 1, lines 59-61). -4-4Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
