Clarity Needed on the STRONGER Patents Act’s Approach to Validity Determinations

The “Support Technology and Research for Our Nation’s Growth and Economic Resilience Patents Act of 2019” or the “STRONGER Patents Act of 2019,” currently under consideration as Senate Bill 2082 and House Resolution 3666, poses questions about the types of decisions that would operate to bar inter partes review (IPR) and post-grant review (PGR) of patent claims. The STRONGER Patents Act is an effort to cure some of the perceived infirmities in the U.S. patent system. While prior versions—introduced in 2015 and 2017—were more wide-ranging, the STRONGER Patents Act of 2019 primarily focuses on the availability of injunctive relief and the susceptibility of patents to IPR and PGR. Among other changes, the bill would effectively overrule the Supreme Court’s eBay v. MercExchange decision, require inter partes and post-grant review petitioners to prove invalidity by clear and convincing evidence, permit only one such review of any given patent claim, and purport to finally end the occasional practice of diverting some the USPTO fees from its operations. While much can (and has) been written about the merits of such reforms, the present comment specifically considers the proposed “Priority of Federal Court Validity Determinations.”
