Fitzpatrick Successfully Obtains Judgment For Client IBM in Second Patent Interference Against Rambus
On December 20, 2012, Fitzpatrick successfully obtained a judgment on behalf of client IBM in its second patent interference against Rambus, involving particular computer memory system configurations. The victory is the culmination of a decade-long controversy that our firm has handled involving this interference, a first patent interference (Perego v. Drehmel, decided on June 24, 2010), and two related district court litigations. As a result of all of these proceedings, a total of 17 Rambus patents containing 625 claims have been invalidated. The Fitzpatrick team in Rambus v. IBM was led by partners Anthony Zupcic, Douglas Sharrott and Robert Fischer, with assistance from associate Josh Calabro.
