Ormco sued Align on Ormco's U.S. patents 5,447,432, 5,683,243, 6,244,861, and later 6,616,444; Align counterclaimed asserting U.S. 6,398,548 and 6,554,611 against Ormco/AOA. The district court found infringement, held some '548 claims invalid, upheld claims 10 and 17, and entered a permanent injunction; the parties settled Feb. 1, 2006, but appeals ended with all asserted '548 claims invalid and escrow returned.
