Doctrine of Equivalents: Impact of Recent Latest Federal Circuit Decisions on Prosecution and Litigation (RECORDING)

In early September, in a brief order, the Federal Circuit announced it was deleting a line it wrote this spring that the doctrine of equivalents (DOE) applies only in cases deemed "exceptional." In a way, the Court was only catching up with two opinions released in August, Eli Lilly & Co. v. Hospira, Inc., and Ajinomoto Co., Inc. v. ITC, that have given hope to patent owners that the DOE is not DOA in a courtroom.

At the center of the issue is one of the exceptions to the general rule that an amendment to a patent application that narrowed a claim creates a bar to equivalents for that claim limitation. Patent owners may rebut prosecution history estoppel by demonstrating that the rationale for an amendment bore no more than a tangential relation to the equivalent in question The importance of this exception cannot be understated as, when applied, prosecution history estoppel can still have a fearsome bite, as demonstrated in another summer decision of the Federal Circuit, Amgen Inc. v. Coherus Biosciences Inc.   

This webinar will help practitioners understand the nuances of the Federal Circuit’s recent DOE jurisprudence, as well as give practical tips both on how to build a case for infringement under the DOE and to defend against it. Our panel includes top litigators, including the two that won these cases in August. It also will offer tips for prosecution at the USPTO, particularly regarding how to narrow claims in the least damaging way.
