This article highlights some of the takeaway lessons from the Patent Trial and Appeal Board’s decisions and guidance with regard to three of the most important issues: the content of the substitute claim set, the burden of proof, and the requirement of the patent holder to establish patentability of the substitute claims.

On February 4, the Federal Circuit affirmed the Patent Trial and Appeal Board’s (“PTAB” or “Board”) first inter partes review (“IPR”) Final Written Decision. In fact, In re Cuozzo Speed Technologies, LLC. was the first appeal of any IPR Final Written Decision, and it related to the first IPR ever filed. As such, this case was significant not only for its substance, but for what the Federal Circuit said regarding some of the more controversial rules promulgated by the Patent Office for IPR proceedings. With regard to the substance of this case, the Federal Circuit agreed with the Board that the reviewed claims in Cuozzo’s patent were invalid as obvious over the prior art. In this case, the claimed technology was directed to indicating speed limits at particular locations on GPS units.

In a 7-2 decision authored by Justice Breyer, the U.S. Supreme Court today held that an “appellate court must apply a ‘clear error,’ not de novo, standard of review” to the evidentiary underpinnings of a district court’s claim construction determination. Teva Pharmaceuticals USA, Inc. v. Sandoz Inc., No. 13-854, slip op. at 1-2 (U.S. Jan. 20, 2015). But what are those evidentiary underpinnings?

Both Congress and the White House have been actively pursuing patent litigation reform in an attempt to combat the perceived “patent troll” problem. Of course, any legislation will impact all patent holders, even though most will not consider themselves to be patent trolls. The disconnect occurs because so-called “trolls” are being equated with all non-practicing entities (“NPEs”) , even though this includes a large number of entities to which that derogatory term was never meant to apply. After all, an NPE is simply a patent holder that does not commercialize the claimed innovation.

Both the executive and legislative branches of the U.S. government have been working on patent reform. For example, the White House released a report last June entitled “Patent Assertion and U.S. Innovation,” accompanied by several executive initiatives and legislative recommendations. In addition, several pieces of legislation have been introduced in both the House and the Senate to address this perceived “patent troll” problem. As Sens. Leahy and Lee explained, the goal of such legislation is “to make it harder for bad actors to succeed, while preserving what has made America’s patent system great.” The difficulty is in narrowly crafting such legislation to specifically address the perceived problems without also ensnaring legitimate patent holders, and without introducing unexpected negative consequences for the patent system as a whole.

On May 3, 2013, the United States Patent and Trademark Office (“USPTO” or “Office”) Rules of Professional Conduct (“USPTO Rules”) went into effect to govern the ethical obligations for representing others before the Office. These new rules are based on the ABA Model Rules for Professional Conduct, and replaced the USPTO Code of Professional Responsibility, which dated back to 1985. Because almost every other U.S. jurisdiction had already adopted some form of the ABA Model Rules, this resulted in a harmonization of ethical standards. The adoption of the USPTO Rules was a significant event for every patent practitioner.
