13. [O]n March 26, 1990, Dr. Holsten discussed
with co-inventor Nigel Neely the possibility of
using particular, alternative classes of chemicals as
carriers in dyeing aramid fabrics and including the
possible use of unsubstituted and mono N-substituted
amides . . . .
14. Holsten recorded his observations from the
discussions at page 37 of his notebook number 216
(Holsten Ex. 6) dated on March 27, 1990 and witnessed
by Michael Simmons . . . on the same date. The
recorded observations by Holsten include the following:
In discussions with Nigel Neely on March 26th, we
revealed similar ideas to each other in that we had
both wondered if unsubstituted and mono-N-substituted
amides might function as basic dye carriers in the
dyeing of aromatic polyamides. Included in such
categories would be benzamide and benzanilide,
both crystalline products with limited or no
significant water solubility . . . . Based upon
our conversation Nigel Neely ordered samples of
acetamide[,] benzamide and benzaniline . . . for
evaluation singly or in combination as basic dye
carriers useful dyeing aromatic polyamides.
Holsten Ex. 6, N.B. 216, p. 37 (3/27/90) . . . .
. . . . .
16. [O]n April 5, 1990, Holsten recorded the
additional observation that N,N-diethyl(m-toluamide)
might additionally be used as a carrier for use in
dyeing aromatic polyamide fibers or fabrics . . . .
Holsten Ex. 7, N.B. 216, p. 47 (4/5/90). The notebook
entry also reflects a disclosure and discussion of the
additional proposed use of N,N-dimethylbenzamide and
benzanilide, additional N-substituted and disubstituted
aromatic carbonamides as candidate dye carriers, as
described to and discussed with Neely as well. . . . .
17. Based on the discussions between Holsten and
Neely, a series of laboratory dyeings were performed at
their direction by . . . Moses Smith, Jr., including
experiments using benzamide and benzanilide . . . as
recorded by Smith on March 30, 1990 (Holsten Ex. 10)
