Appeal No. 95-0124
Application 08/040,911
hypothetical person having ordinary skill in the art would have
found it redundant to encapsulate Palmquist’s fatty acid calcium
salt granules with Ardaillon’s polymeric coating. This follows
because fatty acid calcium salts bypass the rumen and,
accordingly, do not require a polymeric coating for safe passage
therethrough. See Palmquist, column 3, lines 28-41, and see
appellants’ main Brief, page 6, first and second paragraphs; page
11, third paragraph; and page 13, first paragraph.
In their specification, appellants describe a disadvantage
associated with using fatty acid salt products such as those
disclosed by Palmquist. According to appellants,
[a] disadvantage associated with the use of fatty acid
salt products as feed additives is a characteristic
unpleasant odor, which derives from a content of one or
more volatile organic oxygenates in the feed additives.
[Specification, page 2, lines 22-26.]
The present invention provides a solution to the malodor problem
characteristic of Palmquist’s fatty acid calcium salts.
According to the present invention, a fatty acid salt of calcium
or magnesium is encapsulated with a polymeric coating as set
forth in the claims. The encapsulated fatty acid salt product
functions as an odor-free rumen bypass dietary supplement in
ruminant feed. It can be seen that appellants provide a reason
for encapsulating a core matrix comprising at least one C -C
