5431562

Ormco sued Align Technology in the Central District of California for infringement of orthodontic patents; the Federal Circuit noted that U.S. 5,431,562 was a parent of the asserted patents but was not asserted in this suit. The asserted patents were the '444, '861, '243, and '432; after summary judgment, appeals, and a 2009 jury verdict on the '444 patent, the case ultimately resolved in Align's favor on the asserted Ormco claims.
