TT EXTRACTS SETTLEMENT FROM PATSYSTEMS: Electronic screen dealing firm Patsystems has agreed to settle a patent infringement lawsuit brought by Chicago rival Trading Technologies.

The suit was filed yesterday in the United States District Court by TT, alleging that Patsystems has infringed certain of TT's patents.

In a brief statement, Patsystems says the lawsuit will be disposed of once the settlement has been approved by the Court.

Patsystems is the sixth firm to be accused of patent infringement by TT. The Chicago firm has claims outstanding against UK hedge fund manager Man Group, futures commission merchant Refco and bond trading network eSpeed. Chicago brokers Kingstree Trading and Goldenberg Hehmeyer both agreed an out-of-court settlement with TT within days of being sued by the vendor last year.
