SANTA CLARA, Calif., May 13, 2010 (GLOBE NEWSWIRE) -- Align Technology, Inc. (Nasdaq:ALGN) today announced that a complaint was filed against the Company on May 10, 2010 by Christopher J. Leiszler in the United States District Court for the Northern District of California. Dr. Leiszler alleges that Align Technology implemented unfair and fraudulent requirements for the prescription of Invisalign through the Company’s Proficiency Requirements. Dr. Leiszler, a general practice dentist in Kansas City, Missouri, attended Invisalign training in 2008 and had started one Invisalign case since that time. His Invisalign provider status was changed in January 2010 for failing to meet the Company’s proficiency requirements. Dr. Leiszler purports to sue on behalf of himself and all others similarly situated. The complaint seeks a refund of the price paid to Align for Invisalign training.
