This CLE webinar will provide guidance to IP counsel for calculating patent term adjustments, interplay with patent term extensions, examine recent court treatment and proposed legislative changes, and offer approaches for preserving rights and maximizing patent term adjustments and patent term extensions.


In 2012, two decisions held the USPTO had been improperly calculating PTA B-delay for patents involving a request for continued examination Exelixis Inc. v. Kappos (“Exelixis I“) and Novartis v. Kappos). The rulings retroactively added significant time to the patent terms of the patents at issue.

More recently, two district court decisions held that the USPTO calculation was proper (Exelixis v. Kappos (2013) and Abraxis Bioscience v. Kappos (2014), presenting a 2-2 “tie” for the Federal Circuit.

On January 15, 2014, the Federal Circuit broke the tie in favor of the USPTO: filing an RCE stops the accumulation of B-delay. The Federal Circuit rejected the argument that once three calendar years from the application-filing date have come and gone, any time spent in the PTO after that date must be added to the patent term. However, the Federal Circuit also held that the time between allowance and issuance must be added to the patent term as B-delay, if appropriate.

Listen as our authoritative panel of patent attorneys examines the recent developments for PTAs and their potential impact, methods for calculating PTA, what can be done to preserve rights, and offers best practices for maximizing PTA.
