Appeal No. 2003-1018
Application No. 09/093,771
Claims 1 is illustrative of the claims on appeal and reads as follows:
1. A method of separating and isolating a lipid-rich lipid/protein complex from
soybeans, comprising:
adding a substance having the ability to aggregate lipids with proteins selected
from the group consisting of sodium chloride, potassium chloride and ammonium
chloride in amounts from 0.05 to 0.5 M, to a water extract of soybeans, thereby
producing a sedimenting or floating lipid-rich lipid/protein complex,
wherein the lipid content of the complex is at least 45% per aggregate;
isolating the sedimenting or floating lipid-rich lipid/protein complex; and wherein
the weight ratio of lipid to protein of the isolated complex is at least 2-fold higher than
the weight ratio of lipid to protein of the soybeans.
The prior art references relied upon by the examiner are:
Chayen 2,928,821 Mar. 15, 1960
Puski 4,697,004 Sept. 29, 1987
Yoshimura 5,670,624 Sept. 23, 1997
Grounds of Rejection
Claims 1, 5-11, 14-16, 21 and 22 stand rejected under 35 U.S.C. 103(a) as
obvious over Chayen in view of Puski and Yoshimura.
