Video game maker Harmonix succeeds in invalidating asserted litigation claims using IPR
Princeton Digital Image Corp.
Harmonix Music Systems, Inc.
After Harmonix was sued by Princeton Digital Image Corp. in D. Delaware, Finnegan filed a request for inter partes review (IPR) on behalf of Harmonix against all asserted claims. Shortly after filing, Finnegan obtained a rare pre-institution stay of the litigation for Harmonix and other defendants sued over the same patent, avoiding potentially substantial discovery costs. The PTAB issued its final written decision finding four patent claims unpatentable on both proposed § 102 grounds.
