ITEM 8.01 OTHER EVENTS

     On August 31, 2006, Align Technology, Inc. (the "Company") issued a press
release announcing that the United States Court of Appeals for the Federal
Circuit ("CAFC") has declared two out of a total of seventy-one claims in the
Company's US Patent No. 6,398,548 and four out of a total of ten claims in US
Patent No. 6,544,611 to be invalid as "obvious". The CAFC's decision reverses an

press release is attached to this Form 8-K as Exhibit 99.1.
