Appeal 2007-2598 Application 10/378,330 compositions, where the composition contains hop beta acids, food grade organic acids, a soluble source of potassium ions, and an optional antioxidant in a carrier solvent (Br. 2). Independent claim 1 is illustrative of the invention and a copy of this claim is reproduced below: 1. A hop beta acid composition comprising a hop beta acid, a first food grade organic acid, a soluble potassium ion source, and an optional antioxidant in a carrier solvent, wherein the carrier solvent comprises a food grade alcohol, a food grade glycol, or mixtures thereof. The Examiner has relied on the following prior art references as evidence of obviousness: King WO 01/06877 A1 Feb. 01, 2001 Robert S. Igoe and Y. H. Hui (hereafter “Igoe”), Dictionary of Food Ingredients 13, 113, 114, 116 (4th ed., Aspen Publishers, Inc., 2001). ISSUES ON APPEAL Claims 1-32 stand rejected under 35 U.S.C. § 103(a) as unpatentable over King in view of Igoe (Answer 4). Appellants contend that King does not disclose use of a soluble potassium ion source, an amount of potassium ion source in the range of 0.1- 20%, nor an amount of hop beta acid in the range of 0.1-4% (Br. 4). Appellants contend that no motivation has been established for combining the references because Igoe simply defines various food ingredients, namely a “laundry list” of 18 potassium sources, having no relation to antimicrobials or King (Br. 8-9). With regard to the dependent claims, Appellants contend that King and Igoe fail to disclose or suggest the specific amounts of each ingredient as required by the claims (Br. 11-13, separately arguing grouped claims 2, 2Page: Previous 1 2 3 4 5 6 7 8 Next
