On May 4th 2012, the Court of Appeal issued a blow to all Non-practicing entities who files multi- defendant cases as an effort to avoid the requirements of the America Invents Act. The Court in this case held that “Joinder” is not appropriate in multi-defendant patent infringement cases where only commanlity is alleged infringement of same patents.
Denying the reasoning given by the Texas Court, the Court of appeal points out that under the correct test of transaction or occurrence an existence of a single common question of law or fact alone is insufficient to satisfy the transaction- or- occurrence requirement. Thus mere fact that the infringement of same claims of the same patent does not support joinder, even though the claims would raise common questions of claim construction.
