Highmark v. Allcare — Appellate Courts Must Review §285 Exceptional Case Determinations for Abuse of Discretion

Background

Allcare Health Management System held a patent on a method for monitoring managed health care. Allcare sued Highmark Inc., a major health insurer, for patent infringement. The district court ultimately found the case “exceptional” under 35 U.S.C. §285 and awarded Highmark approximately $5 million in attorney fees, concluding that Allcare had pursued the litigation in an objectively baseless manner and with subjective bad faith.

The Federal Circuit reviewed the district court’s exceptional case determination de novo — meaning it gave the lower court no deference and re-examined the question from scratch. Applying that fresh-look standard, the Federal Circuit reversed the fee award, disagreeing with the district court’s assessment of the objective baselessness of Allcare’s legal positions. Highmark petitioned the Supreme Court to address whether de novo review or a more deferential standard applies to §285 exceptional case determinations.

The Court’s Holding

Justice Sotomayor, writing for the Court, held that all aspects of a district court’s §285 exceptional case determination — including the subsidiary question of whether the losing party’s litigating positions were objectively baseless — must be reviewed for abuse of discretion, not de novo. The Court grounded this holding in the principle that discretionary determinations by district courts, who have lived with the case from start to finish, are entitled to appellate deference.

The ruling was decided the same day as Octane Fitness v. ICON Health & Fitness, which liberalized the standard for when a case is exceptional. Together, Octane and Highmark reset the entire framework: Octane tells district courts when they may award fees; Highmark tells the Federal Circuit how much deference to give those decisions on appeal.

Key Takeaways

• Appellate courts must review §285 exceptional case determinations under the abuse of discretion standard, not de novo.
• District courts are in the best position to evaluate the totality of circumstances in patent litigation and deserve deference on fee-shifting decisions.
• Combined with Octane Fitness, the Highmark decision makes fee awards more accessible and harder to overturn on appeal, strengthening the deterrent effect of §285.
• Patent litigants who press weak positions risk fee awards that appellate courts will be reluctant to reverse.

Why It Matters

Highmark is the procedural complement to Octane Fitness. While Octane lowered the bar for what makes a case “exceptional,” Highmark ensures that district court fee decisions will survive appellate review unless the lower court clearly abused its discretion. Together, the two decisions restored teeth to §285 as a litigation conduct deterrent.

For defendants in patent suits — particularly technology companies targeted by non-practicing entities — the Highmark/Octane combination means that aggressively meritless cases are now meaningfully riskier for plaintiffs. District courts that award fees after careful analysis of litigation conduct will have those awards respected on appeal. The decisions have contributed to a gradual cultural shift in patent litigation practice, where the threat of a fee award shapes settlement dynamics and filing decisions.
