  • RehearingRehearing, grantedGranted

    “We agree with Petitioner that we overlooked the significance of that portion of Huet ʼ333 indicating that use of a cosolvent is optional. Upon consideration of the Petition for Rehearing1 and the Response, we grant the Petition for Rehearing and order institution of an inter partes review.” slip op. at 2

    “solvent must include any C1-C4 alcohol. The cosolvent, which can be absolute ethanol, isopropanol, or methanol (Ex. 1005, 6:19–20), is optional (Ex. 1005, 10:45).” slip op. at 11

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

    “We recognize in circumstances similar to those present in this case that it often is questioned why one skilled in the art would “pick and choose” particular ingredients (solvents and crystallization inhibitors in this case) where a reference describes several alternatives. There is an answer. First, the entire disclosure of Huet ʼ333 is in the public domain. One skilled in the art should be free to use any combination described by Huet ʼ333 in proportions that Huet ʼ333 characterizes as being within the skill of the art. Claim 1 of the ’799 patent presumptively removes from that public domain a portion of what is described by Huet ʼ333. Absent some unexpected result obtained by the subgenus of claim 1 of the ʼ799 patent vis-à-vis the broader genus described by Huet ʼ333, it is likely that the subject matter of claim 1 of the ʼ799 patent would have been obvious within the meaning of 35 U.S.C. § 103(a). Patent Owner, in responding on the merits, is free to present evidence of unexpected results.” slip op. at 11
