Clash of MDL and AIA?

We previously reported on the interplay between the Judicial Panel on Multi-District Litigation (“MDL”) under 28 U.S.C. § 1407(a) and the joinder rules under 35 USC § 299 of the America Invents Act (“AIA”). In Unified Messaging Solutions, LLC v. United Online, Inc., et. al., 1-13-cv-00343 (N.D. Il. May 3, 2013) Judge Lefkow recently denied defendants’ motion to sever plaintiff’s infringement claims against them from pretrial consolidation in an MDL case, and rejected their argument that § 299 had been violated.
