Appeal No. 1997-1903 Application No. 08/229,118 The examiner relies upon the following references as evidence of obviousness: Heywood et al. (Heywood) 1,067,033 Apr. 26, 1967 (Great Britain patent specification) Esposito 4,332,613 Jun. 1, 1982 Appellants' claimed invention is directed to a herbicidal mixture of bromoxynil n-octanoate and bromoxynil n-heptanoate. According to appellants, the claimed mixture possesses an unexpectedly lower melting point than the melting point of either of the separate compounds, a significantly lower crystallization temperature than that exhibited by either of the separate compounds, as well as unexpected superiority in herbicidal activity. Appealed claims 1-4, 7-23 and 28-32 stand rejected under 35 U.S.C. § 103 as being unpatentable over Heywood in combination with Esposito. Upon careful consideration of the opposing arguments presented on appeal, we agree with appellants that the prior art applied by the examiner fails to establish the obviousness of the claimed subject matter within the meaning of 35 U.S.C. § 103. Accordingly, we will not sustain the examiner's rejection. -3-Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
