August 25, 2015 – An Eastern District of Texas jury found that Rex Medical, L.P. and Argon Medical Devices, Inc. do not infringe non-practicing entity EVM Systems, LLC’s patent in a verdict form filed on August 24. The jury, as part of the verdict, also upheld the validity of EVM System’s patent. The patent at issue is U.S. Patent No. 8,052,670, entitled: “Medical Device With Slotted Memory Metal Tube.” The case is EVM Systems, LLC v. Rex Medical, L.P. et al., Civil Action No. 6:13-cv-00184 (E.D. Tex., Tyler Division). The ’670 patent is directed to an instrument which uses a slotted memory metal tube to perform or assist in various medical procedures that catch blood clots and prevent them from reaching the lungs. SVM Systems filed the lawsuit in February 2013, alleging that Rex Medical’s vena cava filters infringed its patent.
