National Instruments Wins Round One of Patent Infringement Lawsuit against The MathWorks

1/31/2003 - National Instruments, a leader in measurement and automation, announced that it received a favorable jury verdict in its patent infringement case against The MathWorks in the U.S. District Court for the Eastern District of Texas. The jury found infringement of U.S. Patent Nos. 4,901,221; 4,914,568; and 5,301,336; and non-infringement of 5,291,587. They confirmed all four of the patents to be valid. The patents relate to National Instruments LabVIEW, which contains major innovations in programming design tools.

"We are extremely pleased to have further validation of the LabVIEW patents," said Dr. James Truchard, NI president, CEO and co-founder. "LabVIEW, identified as one of the top 50 electronics industry milestones of the last 50 years, has had a revolutionary impact on engineers and scientists. We invested heavily in the intellectual property that has made LabVIEW and virtual instrumentation possible."

The company will ask the Court to issue an injunction to stop The MathWorks' infringement through its Simulink and related products. A second patent suit filed by NI in U.S. District Court for the Eastern District of Texas is currently pending. This second suit alleges infringement by The MathWorks of six additional patents held by National Instruments.
