Interference No. 103,446
October 17, 1988. Accordingly, we shall limit our
consideration of Sanns' evidence for priority to the extent it
is relevant to proving his priority case based on his theory
that he actually reduced to practice the subject matter of
Count 1 before Martinez' effective filing date of October 17,
1988.
The facts concerning Sanns' actual reduction to
practice are not disputed by the parties. While working in
the Automotive RIM group at Bayer in 1985, Sanns became4
convinced that mica could be used as the filler material for
filled polyurethane and/or polyurea (SR201-204). Sanns
ordered some mica filler material from the J. M. Huber
Corporation (SX17(c)) and inspected the mica to determine its
physical properties (SR220, 223-225). Thereafter in February
1986, Marsh, a technician working for Sanns, prepared two sets
of plaques of polyurethane and/or polyurea in a RRIM machine5
using the mica from J. M. Huber as the filler (SR295, 409).
Marsh recorded the preparation of the plaques in his
laboratory notebook (SX9, SX10). Marsh forwarded the plaques
