Federal Circuit Patent Law: 6 En Banc Petitions Pending

The Federal Circuit is at a critical juncture, with six petitions for rehearing en banc poised to potentially redefine patent law. This unusual concentration signals a deep churn in how intellectual property, especially patents related to AI and technological innovation, will be judged.

Federal Circuit's Patent Law Crossroads: Six En Banc Petitions Loom — Legal AI Beat

Key Takeaways

  • Six petitions for en banc rehearing are pending before the Federal Circuit, an unusually high number.
  • Two key petitions focus on expert testimony admissibility (Rule 702) and patent eligibility (Section 101).
  • Several petitions directly question the court's historically low rate of granting en banc review.
  • The court's internal voting dynamics, particularly concerning Judge Newman's status, could influence decisions.

The hum of anticipation in patent law circles is almost palpable. Not with a new groundbreaking AI model, but with a series of procedural maneuvers that could fundamentally alter the landscape of intellectual property rights. We’re talking about the Federal Circuit, the ultimate arbiter of patent disputes in the U.S., and a backlog of six — count them, six — petitions for rehearing en banc currently sitting on its docket.

This isn’t just noise. It’s a signal. A concentrated cluster of requests for the full court to re-examine recent panel decisions, a move that historically happens at a glacial pace. Think one, maybe two en banc grants a year. Now, imagine six potential doctrinal corrections, all vying for attention. It’s akin to a normally sedate river suddenly facing six significant rapids at once.

And here’s the kicker: several of these petitions don’t just ask for a review; they explicitly question whether the court will continue its famously conservative trajectory in granting en banc review. That’s a direct challenge to the court’s own gatekeeping.

We’re seeing two petitions stand out as particularly potent vectors for change: the post-EcoFactor Rule 702 petition in Barry v. DePuy, which directly tackles the admissibility of expert testimony in patent cases – a cornerstone of any infringement or validity challenge – and the Egyptian Goddess/Gorham challenge in Range of Motion v. Armaid, focusing on the notoriously thorny issue of patent eligibility under Section 101.

Patent Eligibility Under § 101: Oasis Tooling

Ah, § 101. The boogeyman for countless patent holders. This section, governing what constitutes patentable subject matter, has been a revolving door of judicial interpretation, leaving inventors and businesses in a perpetual state of uncertainty. The Range of Motion case, with its focus on the Egyptian Goddess and Gorham standards, is a direct plea for clarity in an area that’s become a minefield. What exactly is eligible for patent protection in an era of rapid software and AI development? The current jurisprudence often feels like trying to nail jelly to a wall – a frustrating and often futile endeavor.

En banc petitions aren’t casual requests. They’re a formal mechanism for a party to argue that a prior panel’s decision either conflicts with established precedent or addresses a question of “exceptional importance.” The full bench then votes. A majority of active judges is needed to grant. Here’s where it gets interesting: the exact composition of the court’s voting bloc is in flux. The current situation with Judge Newman’s “temporary” removal from duty adds an intriguing layer of uncertainty. If she’s not counted, the majority threshold shifts. Six votes instead of seven, potentially making the path to en banc review slightly less steep, but no less contentious.

Why Does This Matter for Patent Eligibility?

The lingering shadow of Alice Corp. v. CLS Bank International and its progeny continues to loom large over patent eligibility. For years, courts have struggled to provide a clear, predictable framework for determining whether an invention is an abstract idea, a law of nature, or a natural phenomenon, rather than patentable subject matter. This ambiguity has stifled innovation, particularly in fields like software and artificial intelligence, where the lines between abstract concepts and patentable applications can be exceedingly fine. The Range of Motion petition, by directly challenging existing interpretations and seeking clarification, could be the catalyst for a much-needed recalibration. It’s not just about the specific patents in play; it’s about setting a stable foundation for future technological advancements.

Is the Federal Circuit Granting En Banc Review Less Often?

The data suggests a trend towards more selectivity. Historically, en banc review was a more common tool for doctrinal correction. However, in recent years, the Federal Circuit has been notoriously tight-fisted with granting these extraordinary reviews. This has led to a buildup of potential issues that some believe are too significant to be left to three-judge panels. The very fact that six petitions are pending, and that several explicitly question the court’s low grant rate, speaks volumes about the perceived importance and unresolved nature of the issues they present. It’s a sign that the bar for en banc review, while high, might be seeing more determined challengers scaling it.

So, what does this all mean for the future of patent law? It means the Federal Circuit is facing a moment of truth. Will it continue to let a trickle of cases define its doctrine, or will it seize this opportunity to provide the clarity and direction that the innovation economy desperately needs? The coming months will be crucial, and the decisions emanating from these six petitions will resonate for years to come.

The court has been granting en banc petitions at a historically low rate of 0-1 per year, and several of the pending petitions explicitly ask whether the court will continue that trajectory.

This concentration isn’t accidental. It’s a symptom of underlying tension, of legal questions that have festered too long. The Federal Circuit, whether it wants to or not, is being pushed toward a reckoning. And that’s where the real story lies – not just in the petitions themselves, but in the system’s response to them.

Will these petitions change patent eligibility rules? It’s possible. If the Federal Circuit grants en banc review for petitions related to patent eligibility, like the one in Range of Motion v. Armaid, it could lead to significant clarification or modification of existing rules.

How likely is it that these petitions will be granted? Historically, en banc review is granted at a very low rate (0-1 per year). However, with six petitions pending and several explicitly challenging this trend, the situation is unusual, making it difficult to predict without further insight into the court’s deliberations.
