Mannatech, Incorporated (NASDAQ: MTEX - News), a global pioneer in the development of high-quality health, weight and fitness and skin care solutions based on nutritional science, obtained a Final Judgment and Permanent Injunction in its lawsuit against Techmedica Health (Techmedica), and Ionx Holdings (Ionx) prohibiting them from the manufacture, use or sale of products infringing Mannatech's patents and requiring them to pay Mannatech $250,000 in damages.

In May 2006, Mannatech filed a lawsuit against Techmedica and Ionx in the United States District Court for the Northern District of Texas, Dallas Division alleging infringement of Mannatech's patents (U.S. Patents 6,929,807; 7,157,431; 7,196,064; 7,199,104; and 7,202,220).¹The parties recently agreed to settle this case and, pursuant to their agreement, United States District Judge Solis entered his Final Judgment and Permanent Injunction.

"This judgment further validates that our patents are good, valid and enforceable under law, and that Mannatech will vigorously enforce its rights under these patents,” said Keith Clark, Mannatech executive vice president and chief legal officer. Mannatech was represented by Eric Pinker, Mark Turk and Renee Strickland, with the Dallas-based litigation firm of Lynn Tillotson Pinker & Cox, LLP.

The final judgment includes findings that Mannatech's patents are "valid and enforceable” and infringed by Techmedica and Ionx. Additionally, it includes a broad injunction that prohibits Techmedica and Ionx from "making, using, offering to sell, selling, or otherwise distributing within the United States, or importing into the United States, infringing products, which include the current formulations of Activive^®, Candidol^®, Claritose^®, Lupazol^®, Nutratose^®, Respitrol^®, Rhumatol^®, Synaptol^® and Viratrol^®, as well as any other products that infringe the patents in suit” and further awards Mannatech damages of $250,000.

The settlement with Ionx and Techmedica comes on the heels of several rulings in the lawsuit favorably construing Mannatech's patents, and is the latest in a series of cases in which Mannatech has obtained injunctions preventing companies from infringing on Mannatech's patents.
