Octane Fitness v. ICON — Supreme Court Loosens Exceptional Case Standard for Patent Attorney Fees Under §285

Background

ICON Health & Fitness sued Octane Fitness for patent infringement, alleging that Octane’s elliptical exercise machines infringed ICON’s patents on a certain type of elliptical stride mechanism. After Octane won on the merits — the district court granted summary judgment of non-infringement — Octane sought attorney fees under 35 U.S.C. §285, which authorizes courts to award attorney fees to the prevailing party in “exceptional cases.”

The district court denied fees, and the Federal Circuit affirmed, applying its two-prong test from Brooks Furniture Manufacturing v. Dutailier International: a case is “exceptional” only if the litigation was both (1) brought in subjective bad faith and (2) objectively baseless. The Federal Circuit also required these elements to be established by “clear and convincing” evidence. Octane argued this test was far too rigid and inconsistent with the text of §285.

The Court’s Holding

Justice Sotomayor, writing for a unanimous Court, rejected the Federal Circuit’s Brooks Furniture two-prong test as “unduly rigid” and inconsistent with §285’s statutory text. The Court held that an “exceptional” case under §285 is simply one that “stands out from others with respect to the substantive strength of a party’s litigating position (considering both the governing law and the facts of the case) or the unreasonable manner in which the case was litigated.”

District courts must assess exceptionality based on the totality of the circumstances, using their own discretion — there is no rigid formula. The Court also lowered the evidentiary standard from “clear and convincing evidence” to a “preponderance of the evidence,” consistent with how other civil fee-shifting determinations are made.

Key Takeaways

• A patent case is “exceptional” under §285 when it stands out from others in the substantive weakness of the losing party’s position or the unreasonable manner of litigation.
• District courts evaluate exceptionality using a totality-of-circumstances approach, not a rigid two-prong test requiring bad faith and objective baselessness.
• The evidentiary standard for proving exceptionality is preponderance of the evidence, not clear and convincing evidence.
• The decision gives district courts more flexibility to deter abusive patent litigation and compensate defendants who successfully defend meritless suits.

Why It Matters

Octane Fitness was a landmark victory for defendants facing meritless patent suits. The old Brooks Furniture test was widely criticized as nearly impossible to satisfy — even cases litigated in obvious bad faith rarely produced fee awards under the rigid two-prong test. By loosening the standard, the Supreme Court gave district courts meaningful tools to sanction patent trolls and other litigants who assert weak or frivolous claims.

Decided on the same day as its companion case Highmark Inc. v. Allcare Health Management System, Octane changed the economics of patent litigation. Companies facing aggressive enforcement campaigns from non-practicing entities — especially in technology, software, and consumer products — gained stronger leverage to threaten fee-shifting if the case lacks merit. The decision has had a measurable deterrent effect on the volume of low-quality patent suits filed in the years since.
