As the Trading Technologies (TT) patent infringement trial
against E-Speed stretched into its third week in Chicago, the
defendant went on the offensive by producing a plethora of
prior art it claims invalidates TT MD Trader patents.
E-Speeds strongest evidence of prior art in over a
weeks worth of presentations and testimony came from
Jean-Cedric Jollant, the former trading application manager for
GL, who testified he created a similar piece of software named
TradePad in September 1998, therefore predating the critical MD
Trader patent date of March 1999.
Jollant testified that he and another GL colleague devised the
idea of TradePad, which featured a static ladder display of
prices with bids and offers on each side that looks almost
identical to the MD Trader in layout and functionality. Jollant
also presented a stack of CDs which he said were back-up copies
of the software he helped create. On each dated CD is an
updated version of TradePad, which was delivered in December
1998 to customers as part of a bundled GL trading software
package called GL Win version 4.31, he said.
