Appeal No. 2006-2333
Application No. 10/280,849
Voelter et al. (Voelter) 4,624,804 Nov. 25, 1986
Daniel M. Mulvihill (Mulvihill), “Functional Milk Protein
Products,” Biochemistry of Milk Products, pp. 94-113 (1994).
Appellants’ claimed invention is directed to a method for
recovering substantially all of the proteins and enzymes from a
raw liquid milk product. The method entails mixing a liquid
milk product with a precipitating agent, such as ethanol or
acetone, and agitating the mixture for a sufficient period of
time to form a precipitate. The liquid milk product may be
whole milk, skim milk, whey or a fraction of milk obtained by
acid precipitation, alkaline precipitation or by ultra-
filtration.
Appealed claims 1-4, 7-11, 13 and 14 stand rejected under
35 U.S.C. § 103(a) as being unpatentable over Mulvihill in view
of Voelter.
Appellants do not present separate arguments for any
particular claim on appeal. Accordingly, all the appealed
claims stand or fall together with claim 1.
We have thoroughly reviewed each of appellants’ arguments
for patentability. However, we are in complete agreement with
the examiner that the claimed subject matter would have been
obvious to one of ordinary skill in the art within the meaning
