The Federal Circuit’s recent ruling in MaxPower Semiconductor Inc. et al v. Rohm Semiconductor USA, LLC highlights the interplay between the liberal federal policy favoring arbitration agreements and the Patent Trial and Appeal Board’s (“PTAB”) authority as an agency tribunal having a broad role to protect the public interest in ensuring the quality of patents.

Challenging the validity of a patent through the inter partes review (IPR) process at the PTAB is a conventional alternative to litigating invalidity in federal court. MaxPower addressed the question of whether the PTAB will defer to an agreement to arbitrate that did not expressly preclude the parties from proceeding before the PTAB.

Doctrine of equivalents (DOE) can be applied as a mechanism to hold a party liable for patent infringement even if the product or process does not literally infringe a patent claim, if the difference is “insubstantial”. Warner-Jenkinson Co. v. Hilton Davis Chem. Co. (1997) Findings of infringement under DOE, particularly in biotechnology related cases, have often been considered an exception rather than the rule. One such exception is the recent Federal Circuit nonprecedential decision in Jennewein Biotechnologie GmbH v. International Trade Commission, September 17, 2020, Chen, R. (Glycosyn LLC, the patent owner, joined as an Intervenor). The Federal Circuit affirmed an exclusion order from the International Trade Commission (ITC) relying on an application of DOE to find infringement supported by substantial evidence.

In the wake of the nomination of Kathi Vidal as Director of the USPTO, there will be significant attention paid to the agency’s responses to calls from both the executive and legislative branches to remake the agency’s perceived role in shaping the pharmaceutical pricing landscape.

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.   …

Striking a blow to patent applicants seeking to assert inventorship by artificial intelligence (“AI”) systems, the U.S. District Court for the Eastern District of Virginia ruled on September 3, 2021 that an AI machine cannot qualify as an “inventor” under the Patent Act.  The fight is now expected to move to the Federal Circuit on appeal.

On August 23rd, the Federal Circuit upheld in part and reversed in part a decision from the Patent Trial and Appeal Board’s (PTAB or Board) concerning Ethicon’s patent on a robotic surgical tool, holding that the Board’s finding of no motivation to combine is not supported by substantial evidence. In doing so, the court determined the PTAB “went too far” in its holding of non-obviousness by requiring Intuitive to specifically identify a preexisting surgical device performing as many functions as required by the Ethicon patent; it was enough that the prior art established such a device was “at least possible.” …

On August 5, 2021, the Federal Circuit withdrew its October 2020 opinion in GSK v. Teva, summarized in this post on induced infringement of method-of-treatment claims, and issued an opinion that reiterated the prior holding but sought to clarify its reasoning. GlaxoSmithKline v. Teva. Specifically, the majority stated that a generic manufacturer’s touting of AB equivalence to a brand drug is generally not evidence of intent to induce infringement—but in the specific facts of this case it did support inducement, because the Court found ample evidence tying claim limitations to statements in Teva’s label even though the patented method was omitted as a distinct indication. The Court also found that Teva’s advertising statements regarding treating “heart failure” evidenced intent to induce physicians to prescribe the drug to treat CHF.

The question whether an artificial intelligence (“AI”) system can be named as an inventor in a patent application has obvious implications for the life science community, where AI’s presence is now well established and growing. For example, AI is currently used to predict biological targets of prospective drug molecules, identify candidates for drug design, decode genetic material of viruses in the context of vaccine development, determine three-dimensional structures of proteins, including their folding form, and many more potential therapeutic applications.

Over the last seven years there has been commotion in Obviousness-type Double Patenting (“ODP”) practice. One of the latest cases to spur a considerable amount of interest is Mitsubishi Tanabe Corp. v. Sandoz, Inc., which is currently on appeal to the Federal Circuit (“CAFC”). While a detailed review of this case is not the intent of this post, as a fair number of practitioners have provided insightful coverage, an historical overview is helpful for framing the decision and issues that need clarification from the CAFC.
