Mannatech’s Patents Further Validated with Judgments against Seven Companies

Mannatech, Incorporated (NASDAQ: MTEX), a global pioneer in the development of high-quality health, weight and fitness and skin care solutions based on nutritional science, announced today the entry of Agreed Judgments in a lawsuit against Micro Health Solutions, Wy's Enterprises of Springfield, Florida Nutri Labs, Angel Care, USA, and New Sun, prohibiting all five companies from the manufacture, use or sale of products infringing Mannatech’s patents for its proprietary Glyconutrient technology.

Mannatech filed a lawsuit against these five companies, as well as EvenBetterNow, LLC, Oasis Advanced Wellness, LLC, Roex, Inc., VDF FutureCeuticals, Inc., and Country Life, LLC, in March 2010 in the United States District Court for the Northern District of Texas, Dallas Division, alleging infringement of four of Mannatech’s patents (U.S. Patents 6,929,807; 7,157,431; 7,199,104; and 7,202,220). United States District Judge Reed O’Connor entered his judgments against these five companies in June. Judgments against EvenBetterNow and Oasis were previously entered in April.

"We are proud to obtain successful judgments against seven of the ten companies in this lawsuit and we intend to vigorously pursue our claims against the remaining defendants,” said Keith Clark, Mannatech executive vice president and chief legal officer. "This is a significant milestone for Mannatech in defending the strength and validity of our brand, products and patents.”

The court judgments all include broad injunctions that prohibit Micro Health Solutions, Wy's Enterprises of Springfield, Florida Nutri Labs, Angel Care, USA, and New Sun from "making, using and offering to sell, selling, or otherwise distributing within the United States, or importing into the United States the infringing products as well as colorable imitations” as well as "providing assistance to others in making, using, offering to sell, selling, or otherwise distributing [infringing products] within the United States, or importing into the United States.”

Additionally, the judgments prohibit the five companies from supplying all or a substantial portion of the components of products that would infringe the patents in suit.

The previous judgments entered against EvenBetterNow and Oasis as well as these five judgments resolve the claims against seven of the ten companies that Mannatech recently filed a lawsuit against for infringing on its patents. Mannatech is represented by Eric Pinker, Mark Turk and Renee Strickland, with the Dallas-based litigation firm of Lynn Tillotson Pinker & Cox, LLP.
