Patent Interference No. 103,812
Rosenquist attached these pages from Mr. Butler's notebook to page 304 of his own laboratory
notebook. See RX 6; RR, p. 7, paragraph 9.
Dr. Rosenquist further testified that on about February 11, 1994, the molecular weights of
the three polycarbonate specimens were measured by GPC (gel permeation chromatography).
See RR, p. 8, paragraph 10. According to page 305 of Dr. Rosenquist's notebook, Dr.
Rosenquist obtained the molecular weight data from Jim Wilson. See RX 6. However, Mr.
Wilson was unable to locate that data in the electronic records where data of that type is usually
stored. See RR, p. 44, paragraph 5.
In any event, according to Dr. Rosenquist, he received the "MW" and "MN"
measurements for the three specimens and made the necessary calculations on February 11,
1994. The results, including "Target MW," were recorded on page 305 of Dr. Rosenquist's
notebook. The molecular weights ("MW") reported for the three specimens were 32,300, 25,900
and 21,700, respectively. See RR, p. 8, paragraph 10; fifth page of RX 6.
In his declaration, Dr. Rosenquist explains that (RR, p. 8, paragraph 10):
[The data reported on page 305 of Dr. Rosenquist’s laboratory notebook (RX 6)]
shows that the product 5249-58 is indeed functioning as a monofunctional
endcapping agent to control polymer molecular weight, producing essentially the
same polymerization control as the same proportion of standard phenol
endcapping agent.
Significantly, there is no direct evidence that the ester linkage required by the count was
formed in any one of the three interfacial polycarbonate polymerizations performed by Mr.
Butler from February 8 through February 10, 1994. See Rosenquist patent claim 1.
