Intellectual property and competition In 1999, the U.S. Department of Justice filed a lawsuit against MathWorks and
Wind River Systems alleging that an agreement between them violated
antitrust laws. The agreement in question stipulated that the two companies agreed to stop competing in the field of dynamic control system design software, with MathWorks alone selling Wind River's MATRIXx Software and that Wind River would stop all research and development and sales in that field. Both companies eventually settled with the Department of Justice and agreed to sell the MATRIXx software to a third party. MathWorks had total sales of $200 million in 2001, with dynamic control system design software accounting for half of those sales. MathWorks's Simulink software was found to have infringed 3 patents from
National Instruments related to data flow diagrams in 2003, a decision which was confirmed by a court of appeal in 2004. In 2011, MathWorks sued
AccelerEyes for copyright infringement in one court, and patent and trademark infringement in another. AccelerEyes accepted
consent decrees in both cases before the trials began. In 2012, the European Commission opened an
antitrust investigation into MathWorks after competitors alleged that MathWorks refused to grant licenses to its intellectual property that would allow people to create software with
interoperability with its products. The case was closed in 2014 without filing any charge.
Logo The logo represents the first vibrational mode of a thin L-shaped membrane, clamped at the edges, and governed by the
wave equation, which was the subject of Moler's thesis. MathWorks sponsored the mathematics exhibit at London's
Science Museum. In the coding community, MathWorks hosts MATLAB Central, an online exchange where users ask and answer questions and share code. MATLAB Central currently houses around than 145,000 questions in its MATLAB Answers database. The company actively supports numerous academic institutions to advance
STEM education (primarily through the use of MathWorks products), including giving funding to MIT Open Courseware and MITx. ==References==
