On April 11, 2013, Shire filed its patent infringement lawsuit (available here) against Neos for alleged infringement of U.S. Reissued Patent Nos. RE 42,096 and RE 41,148. Shire makes and sells ADDERALL XR, which it asserts embodies the patents-in-suit. Neos, according to Shire, submitted a new drug application, thereby infringing the patents-in-suit.
Shire is represented by Richard Sayles and Mark Strachan, both of Sayles Werbner, P.C.
