Attorneys' fees under § 285

35 U.S.C. § 285 ("The court in exceptional cases may award reasonable attorney fees to the prevailing party."); Octane Fitness, LLC v. ICON Health & Fitness, Inc., 572 U.S. 545 (2014); Highmark Inc. v. Allcare Health Mgmt. Sys., Inc., 572 U.S. 559 (2014).

Section 285 authorizes a district court to award attorneys' fees to the prevailing party in exceptional cases. Octane Fitness replaced the old Brooks Furniture standard with a flexible totality-of-the-circumstances inquiry, lowered the burden of proof to a preponderance, and committed the analysis to the discretion of the trial court. Highmark, decided the same day, made appellate review deferential.

The rule

"The court in exceptional cases may award reasonable attorney fees to the prevailing party." 35 U.S.C. § 285. An exceptional case 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." Octane Fitness, LLC v. ICON Health & Fitness, Inc., 572 U.S. 545, 554 (2014). Either weakness on the merits or unreasonable conduct will do; both together is common.

Statutory and constitutional source

Section 285 was enacted in 1952 as a successor to a 1946 fee-shifting provision. Until 2014, the Federal Circuit had read the statute through the lens of Brooks Furniture Mfg., Inc. v. Dutailier Int'l, Inc., 393 F.3d 1378 (Fed. Cir. 2005). Brooks required the patentee to show by clear and convincing evidence either (i) "material inappropriate conduct related to the matter in litigation" or (ii) that the litigation was both "brought in subjective bad faith" and "objectively baseless." Octane Fitness held the Brooks framework "overly rigid" and "unduly inflexible" and rejected each of its principal limitations. 572 U.S. at 553–58.

The American Rule against fee-shifting governs absent a statutory exception. Section 285 is one such exception. The constitutional foundation is the Patent and Copyright Clause, Article I, § 8, cl. 8: Congress's authority to regulate the patent right includes the authority to provide remedies for its abuse. See Title 35 reference.

The framework the courts apply

Octane Fitness and totality of the circumstances

Octane Fitness set the test now applied in every § 285 motion. The Court held that:

Highmark and abuse-of-discretion review

Highmark Inc. v. Allcare Health Mgmt. Sys., Inc., 572 U.S. 559 (2014), companion to Octane, held that an exceptional-case determination is committed to the sound discretion of the district court and is reviewed on appeal for abuse of discretion. The earlier Federal Circuit practice of reviewing the objective-baselessness prong of Brooks de novo no longer applies. The shift is significant in practice: post-Highmark, the Federal Circuit affirms district court rulings on § 285 in the great majority of appeals.

Substantive weakness

A case may be exceptional because the losing party's litigating position is unusually weak — for example, where:

Unreasonable manner of litigation

A case may also be exceptional because of the manner in which it was litigated, even where the substantive position is not frivolous:

Inequitable conduct as exceptional

A finding of inequitable conduct in patent prosecution typically supports a finding of exceptional case under § 285. Therasense, Inc. v. Becton, Dickinson & Co., 649 F.3d 1276 (Fed. Cir. 2011) (en banc), tightened the standard for inequitable conduct itself, but where the defense succeeds, fee-shifting frequently follows. The exceptional-case finding does not require independent proof of bad faith beyond what supported the inequitable-conduct holding.

Considerations involving NPEs

The patent assertion behavior of non-practicing entities ("NPEs" or, pejoratively, "patent trolls") has been the principal factual context for § 285 awards in the lower courts. Courts have identified recurrent NPE patterns: nuisance-value settlement demands, refusal to disclose infringement contentions until late, dismissal in the face of dispositive motion practice, and suing on patents the asserter knows have been narrowed by IPR or claim construction in earlier cases. None of these patterns alone is dispositive. But where they accumulate against a particular plaintiff, they will support exceptionality. SFA Sys., LLC v. Newegg Inc., 793 F.3d 1344 (Fed. Cir. 2015) (declining to require a "pattern of vexatious litigation" as a precondition).

Burden and proof

The party seeking fees must prove exceptionality by a preponderance of the evidence. Octane Fitness, 572 U.S. at 557–58 (rejecting the Brooks clear-and-convincing standard). The court's exceptionality determination is reviewed for abuse of discretion. Highmark, 572 U.S. at 564.

The amount of fees is reviewed for abuse of discretion. The court applies the lodestar method: hours reasonably expended multiplied by reasonable hourly rates. Lumen View Tech. LLC v. Findthebest.com, Inc., 811 F.3d 479 (Fed. Cir. 2016). Some courts also award expert fees as part of the § 285 award; others limit § 285 to attorney time and require parties to seek expert costs under Rule 54(d) or other authority.

Section 285 provides for fees in favor of the "prevailing party," whether plaintiff or defendant. A defendant who succeeds on summary judgment of non-infringement, who obtains a judgment of invalidity, or who obtains a judgment after trial may move under § 285. A plaintiff that prevails on liability may also recover. The statute does not require the moving party to be wholly victorious — partial success suffices. SSL Servs., LLC v. Citrix Sys., Inc., 769 F.3d 1073 (Fed. Cir. 2014).

Interaction with related doctrines

Section 285 is conceptually independent of willfulness under § 284 and operates on the manner of litigation as much as on infringement conduct. The two often appear together: a finding of willful infringement frequently supports an exceptional-case finding, and a finding of inequitable conduct nearly always does. They are not, however, equivalent. The Supreme Court drew the parallel itself in Halo. Halo Electronics, Inc. v. Pulse Electronics, Inc., 579 U.S. 93, 110 (2016).

Other fee authorities remain available. Federal Rule of Civil Procedure 11 sanctions, 28 U.S.C. § 1927 vexatious-litigation fees, and the court's inherent power may also support fee awards, sometimes against attorneys personally. Phigenix, Inc. v. Genentech, Inc. and other cases recognize parallel or alternative authorities. Section 285 itself is limited to fees against parties.

Section 285 interacts with § 101 dismissals (where Alice-flagged claims are pursued), claim construction (post-Markman maintenance of foreclosed positions), and IPR outcomes (continuing assertion of claims that survived only narrowly or have been amended).

Practical notes

Timing and procedure

A § 285 motion is filed under Federal Rule of Civil Procedure 54(d)(2), which sets a 14-day deadline (running from entry of judgment) absent local-rule extension. Many districts have local rules expanding that period. The motion is typically deferred until appeal completion in some districts; in others the trial court rules promptly and the appeal of the merits and the fee award proceeds together.

Building a § 285 record during the case

Defendants who anticipate a § 285 motion should:

Calculating fees

Fee submissions ordinarily include detailed time records, attorney biographies supporting hourly rates, and comparable-rate evidence from local markets. Courts apply a reasonableness lens: excessive staffing, block billing, and clerical work are commonly reduced. Fees are recoverable for the entire case as litigated unreasonably or, where exceptionality is more localized, only for the unreasonable portion. Therasense, Inc. v. Becton, Dickinson & Co., 745 F.3d 513 (Fed. Cir. 2014) (causation in fee award).

Variation across districts

Patterns vary across districts. The District of Delaware and the Northern District of California grant § 285 motions at moderate rates. The Eastern District of Texas, despite its dense patent docket, has historically issued few § 285 awards, although that pattern has shifted in recent years. The Western District of Texas has begun developing its own post-trial fee jurisprudence.

Joint and several liability; counsel sanctions

Section 285 fees are imposed against parties, not their counsel. Sanctions against counsel personally proceed under Rule 11, § 1927, or inherent authority and require independent showings.
