It’s well-known that concerns about patent assertions by non-practicing entities were part of the impetus for the America Invents Act of 2011.  In order to prevent multiple unrelated defendants from being added to the same infringement suit on the sole basis that they are accused of infringing the same patent, the AIA added the so-called “misjoinder” provision (35 U.S.C. § 299) to the patent laws.  Briefly, Section 299 provides that defendants are properly joined if (1) infringement is asserted against the defendants based on the same transaction or occurrence or as to the same accused product or process, and (2) questions of fact common to all defendants will arise in the action.  Over the past year and a half, courts have been grappling with evaluating whether otherwise unrelated defendants are properly joined in infringement actions.  In his recent ruling in an Eastern District of Texas case involving IEEE 802.3 Ethernet technology, Magistrate John D. Love held that standards-compliant system-on-a-chip (SoC) suppliers may be properly joined with their customers under Section 299.
