Appeal No. 1998-2941 Page 39
Application No. 08/061,985
Reexamination Control No. 90/003,682
1. Claims 12 to 15, 18/12 and 19/12 are rejected under
35 U.S.C. § 103 as being unpatentable over the News & Observer
article in view of Stadelman and/or Food in Canada.
The News & Observer article discloses that "NCSU
researchers crack the secret of long shelflife for eggs"
(i.e., liquid whole eggs). The News & Observer article states
that by using a higher pasteurization temperature and sterile
packaging an extended shelf life of refrigerated liquid whole
eggs may be obtained. The News & Observer article discloses
that the new process keeps eggs in good shape for up to three
months. The News & Observer article teaches that laboratory
equipment similar to machinery now used in egg processing was
used by the researchers.
Stadelman discloses (pp. 161, 175-180) that it was known
in the art to pasteurize liquid whole eggs by passing the
liquid whole eggs as a continuous stream through the
pasteurizing apparatus. Stadelman also teaches (p. 180) that
a turbulent flow pattern is desired.
