On October 17, the USPTO published a Notice of Proposed Rulemaking (NPRM) that would place significant new limits on America Invents Act (AIA) reviews, barring institution unless petitioners stipulate not to raise invalidity challenges under Section 102 or 103 in parallel litigation, where the parallel forum would likely address validity on that basis before the Patent Trial and Appeal Board (PTAB) issues its final written decision, or where the patent’s validity has already been upheld by another forum. Public comments submitted by the December 2 deadline included feedback from a number of notable petitioner-defendants, licensors, NPEs, and other entities engaged in patent monetization. Meanwhile, the USPTO also received a letter in support of its proposal from some of the cosponsors of a PTAB reform bill before Congress—and a competing letter opposing the proposal from former legislators that either voted for the AIA or have since supported it.

Central District of California Judge Serena R. Murillo recently marched through seven unrelated former Intellectual Ventures LLC (IV) patents asserted by Empire IP LLC plaintiff IoT Innovations LLC against Lutron Electronics, invalidating them one by one under Alice. Lutron quickly notified Southern District of Florida Judge Melissa Damian, who presides over the other case filed by IoT Innovations against Lutron, of the development, arguing that the ruling bolsters its arguments in a pending motion in that court for transfer to California. IoT Innovations counters that the invalidation order came “in a different case involving different patents, different claim language, different technological fields, and” different controlling law, the plaintiff urging Judge Damian therefore to “ignore it”.
