Judge T. John Ward upheld a jury verdict reached in January 2003 that found validity and infringement of U.S. Patent Nos. 4,901,221, 4,914,568 and 5,301,336. The patents relate to NI’s LabView software. NI has a second patent lawsuit currently pending in the same court, which alleges infringement by The MathWorks of four more LabView-related patents.

NI is presently offering LabView Simulation Interface Toolkit, which adds the power of LabView’s user interface to the Simulink environment. With NI’s toolkit, design engineers can use LabView-based user interfaces to intuitively control and view data in their control models. The toolkit gives The MathWorks customers a licensed way to control and view Simulink data under NI’s patents currently at issue in the patent infringement lawsuit.

‘We’re pleased that the court upheld the jury verdict,’ says Dr. James Truchard, NI’s president, CEO and co-founder. ‘LabView has had a revolutionary impact on scientists and engineers with its innovative virtual instrumentation approach. We’ve invested heavily in the intellectual property in LabView and the judge’s ruling further protects our intellectual property.’
