Federal Court Rules in Favor of Mannatech Ambrotose Patents

Mannatech, Incorporated (NASDAQ: MTEX), a leading developer and provider of dietary supplements and skin care solutions, today announced that the federal court in the Northern District of Texas issued a Markman ruling in the company's favor against Glycobiotics International Inc., in a patent infringement lawsuit based on Mannatech's Ambrotose(R) and Advanced Ambrotose(R) products.

After considering the plain language of the patents, patent prosecution history and briefing and evidence presented by the parties, the Court issued a Markman ruling effectively shutting down Glycobiotics' interpretation. The Court's ruling allows Mannatech to continue to pursue its patent infringement claims against Glycobiotics International Inc., with a trial setting expected for late fall.

Mannatech is currently pursuing two patent infringement lawsuits against Glycobiotics International Inc., and K.Y.C. Inc., d/b/a Techmedica Health Inc. The lawsuits, which are still pending, are in response to several competitors using Mannatech's technology to create and offer copycat products.
