In Sawstop Holding LLC v. Vidal the Federal Circuit confirmed what many practitioners suspected— the Patent and Trademark Office will only award a patent term adjustment to offset a delay caused by appellate review of a patent prosecution if the appeal results in allowable claims ready for issuance.
Confronting a life sciences patentee with its statements to regulatory bodies (such as the FDA) is a textbook defense strategy in patent litigation. After all, communications with regulatory bodies are often performed by non-attorneys who may not appreciate the consequences of their statements in future litigation. And while in ideal circumstances the patentee’s attorneys will ensure accurate and consistent communications and try to put potentially inconsistent statements in context, it is not always possible to do so once the genie is out of the bottle. Belcher Pharmaceuticals, LLC v. Hospira, Inc., exemplifies the dire consequences that can result from inconsistent communications with regulators—particularly if a defendant can point to a single source for those communications.
