Jury Validates Key Mannatech Technology Patents Involving Its Ambrotose(R) Glyconutrien...(oducts International formerly Glycobioti...),Health

"A company's ability to stop patent infringement requires not only the issuance of a patent, but also a favorable court interpretation of the patent and a defense of its validity," said Keith Clark, general counsel at Mannatech. "This decision, coupled with the company's successful outcomes in the Markman hearing rulings last year, paves the way for protecting these critical Mannatech technology patents moving forward."

The verdict was delivered on Friday, May 9, 2008, in the U.S. District Court for the Northern District of Texas, Dallas Division. Jurors reached their decision following five days of testimony before Federal Magistrate Jeff Kaplan.

Mannatech was represented by Lynn Tillotson & Pinker, LLP attorneys Eric W. Pinker, P.C., Mark E. Turk, Renee S. Strickland and Britta Erin Stanton as well as Chalker Flores, LLP attorneys Edwin Flores, Daniel J. Chalker and Scott A. Meyer.
