BALTIMORE, MD -- (Marketwire) -- 08/20/09 -- Brower Piven, A Professional Corporation announces that a class action lawsuit has been commenced in the United States District Court for the Northern District of California on behalf of purchasers of the common stock of Align Technology, Inc. ("Align Technology" or the "Company") (NASDAQ: ALGN) during the period between January 30, 2007 and October 24, 2007, inclusive (the "Class Period").

No class has yet been certified in the above action. Members of the Class will be represented by the lead plaintiff and counsel chosen by the lead plaintiff. If you wish to choose counsel to represent you and the Class, you must apply to be appointed lead plaintiff no later than October 13, 2009 and be selected by the Court. The lead plaintiff will direct the litigation and participate in important decisions including whether to accept a settlement and how much of a settlement to accept for the Class in the action. The lead plaintiff will be selected from among applicants claiming the largest loss from investment in the Company during the Class Period. You may contact Brower Piven (through hoffman@browerpiven.com or 410/986-0036) to answer any questions you may have in that regard.

The complaint accuses the defendants of violations of the Securities Exchange Act of 1934 by virtue of the Company's failure to disclose during the Class Period that the Company had shifted the focus of its sales force to clearing backlog, causing a significant decrease in the number of new case starts, thus rendering the Company's class period statements concerning the Company's business, operations and financial prospects materially false and misleading. According to the complaint, after the Company revealed, on October 24, 2007, that in an effort to clear prior backlog the Company had failed to focus enough effort on filling the pipeline for new case starts and that the Company had to refocus its field and channel marketing teams to generate new case growth, the value of Align's stock declined significantly.
