Patent Litigation

Attorney's Fees

After Octane Fitness (2014), § 285 exceptional-case fee awards are a real deterrent against weak patent assertions and frivolous defenses — available based on litigation conduct alone, not just objective baselessness.

What is § 285 and when can attorney's fees be awarded in patent cases?

35 U.S.C. § 285 provides for fee-shifting in exceptional patent cases.

Statutory Text. 'The court in exceptional cases may award reasonable attorney fees to the prevailing party'

Key Elements

  • (a) 'exceptional cases' — not all cases
  • Only cases that stand out from others
  • (b) 'may award' — discretionary
  • The court can decline to award fees even in an exceptional case
  • (c) 'prevailing party' — the party who wins the case (defendant or plaintiff may be the prevailing party)
  • OCTANE FITNESS v. ICON HEALTH & FITNESS (S.Ct. 2014): fundamentally changed the § 285 standard

Before Octane

  • Under the Brooks Furniture test, an exceptional case required either: (1) litigation brought in subjective bad faith
  • OR (2) the litigation was objectively baseless
  • And the determination was reviewed de novo on appeal

Octane Fitness Holding

  • The Brooks Furniture test was too rigid
  • An exceptional case is one that stands out from others with respect to: (a) the substantive strength of a party's litigation position (considering both the governing law and the facts)
  • OR (b) the unreasonable manner in which the case was litigated
  • The district court has discretion to consider the totality of the circumstances

No Requirement for Objective Baselessness

  • Octane Fitness eliminated the need to prove the case was objectively baseless
  • A case can be exceptional based on the weakness of the position or on litigation conduct alone
  • HIGHMARK v. ALLCARE HEALTH MANAGEMENT (S.Ct. 2014): § 285 awards are reviewed for ABUSE OF DISCRETION (not de novo)
  • This made fee awards more durable on appeal
  • Combined with Octane, fee awards became significantly more available.

What factors make a patent case exceptional under § 285?

Courts look at the totality of the circumstances to determine exceptionality.

Substantive Strength of Litigation Position

Weak Patent Assertion

  • Filing suit on a patent with known invalidity
  • Asserting infringement without adequate pre-suit investigation
  • Pursuing claims clearly barred by exhaustion or prior license
  • Ignoring obvious claim construction

Weak Defenses

  • Asserting invalidity defenses without evidentiary support
  • Raising defenses solely for delay
  • Ignoring strong evidence of infringement

Unreasonable Manner of Litigation

Abusive Litigation Tactics

  • Vexatious discovery (excessive depositions; burdensome document requests without proportionality)
  • Misrepresentations to the court
  • Hiding information during claim construction
  • Filing motions solely for delay

Demand Letter Practice

  • Demanding settlement for amounts below litigation cost (nuisance value)
  • Mass sending form letters
  • Threatening frivolous litigation

Specific Exceptional Conduct

  • Failing to perform adequate pre-suit investigation
  • Continuing to litigate after learning of fatal claim construction issue
  • Asserting the same patent against hundreds of defendants with boilerplate complaints
  • Pursuing claims in bad faith after clear non-infringement is established

Factors Courts Consider

  • The objective strength of the legal position
  • The subjective good faith of the litigant
  • The reasonableness of conducting investigation before filing
  • Consistency with prior positions

Defendant's Exceptional Conduct

  • Patent owners can also seek fees for exceptional defendant conduct: defending with frivolous invalidity arguments
  • Abusive discovery tactics by defendant
  • Relying on baseless claim construction

Amount of Fee Award

  • The prevailing party recovers 'reasonable' attorney's fees
  • The court may limit fees to the exceptional aspects of the case
  • Fees may not cover the entire litigation if only part was exceptional.

How do attorney's fees awards affect NPE and patent troll litigation?

The threat of attorney's fees is a significant tool against abusive patent assertion.

Pre-octane NPE Landscape

  • Before Octane Fitness (2014), it was difficult to obtain fee awards against NPEs
  • NPEs (non-practicing entities, colloquially 'patent trolls') filed infringement suits knowing defendants would settle rather than spend $1M+ litigating
  • Defendants often settled even weak cases to avoid litigation costs

Post-octane Impact

  • After Octane Fitness, district courts awarded fees more frequently against NPEs with weak positions
  • This created a deterrent against mass-mailing demand letters
  • Courts awarded fees for: inadequate pre-suit investigation
  • Using form complaints without analyzing each defendant's products
  • Pursuing claims after obvious non-infringement was demonstrated

Fee Awards in Practice

  • Apple v. Uniloc USA (NDCA 2021): court awarded $3.5M fees against Uniloc after finding exceptional conduct
  • Courts in WDTX and NDCA have been active in fee awards post-Octane

Defensive Strategies Against NPE Assertions

  • Respond to demand letters by pointing out deficiencies in the infringement analysis
  • Early motion for summary judgment of non-infringement
  • If successful, move for fees under § 285
  • File IPR to invalidate asserted patents

Demand Letter Response Strategy

  • If you receive a demand letter: request all claim charts
  • Analyze the infringement theory
  • Determine whether the patent is even arguably infringed
  • If clearly not infringed, respond in writing to create a record for fees

Pro Se and Small-entity Plaintiffs

  • Courts have discretion to consider the financial circumstances of the losing party when awarding fees
  • A fee award against an individual inventor who loses may be reduced or waived
  • Against a funded NPE, courts are less likely to reduce.

How does the pre-suit investigation requirement affect § 285 fee awards?

Adequate pre-suit investigation is a key factor in § 285 exceptionality analysis.

Rule 11 Obligations (Frcp 11)

  • Before filing any patent infringement complaint, counsel must: conduct reasonable investigation of the factual basis for each allegation
  • Confirm that each asserted claim is plausibly infringed by the accused product
  • Not file for an improper purpose (delay, harassment)
  • § 285 INVESTIGATION STANDARD: courts use evidence of pre-suit investigation (or lack thereof) in § 285 analysis
  • What did counsel do before filing? was a claim chart prepared? was the accused product analyzed against the claims? was prior art considered? was the prosecution history reviewed? INADEQUATE INVESTIGATION PATTERNS: (a) using form complaints that don't analyze each defendant's specific products
  • (b) asserting patent claims without understanding how the accused product works
  • (c) claiming infringement of method claims without determining who performs each step
  • (d) failing to obtain the accused product for analysis
  • (e) relying on website descriptions without technical analysis

Documentation of Pre-suit Investigation

  • Plaintiff's counsel should document: date and nature of pre-suit investigation
  • Who performed the analysis (claim charts; product acquisition)
  • What information was available

Defendant's Right to Discovery on Investigation

  • Defendants may seek discovery on whether pre-suit investigation was adequate
  • Depose plaintiff's counsel (within limits)
  • Request claim charts

Timing of Exceptional Case Motion

  • Typically filed after final judgment
  • But early resolution is possible: motion for fees after case is dismissed
  • Motion after summary judgment of non-infringement
  • Courts may also award fees if plaintiff dismissed voluntarily after defendant raised substantive defenses.

What is the relationship between § 285 and other fee-shifting mechanisms in patent cases?

Patent litigation has multiple overlapping fee-shifting provisions: § 285 vs..

Rule 11 (Frcp 11)

  • § 285 applies after the case is over (exceptional case standard)
  • Rule 11 applies to specific frivolous filings (complaint; brief; motion)
  • Rule 11 requires a 21-day safe harbor period (the objecting party must notify the filer to correct before seeking sanctions)
  • § 285 has no safe harbor
  • § 285 vs.

28 U.s.c. § 1927 (Unreasonable Multiplication)

  • § 1927: counsel personally liable for fees caused by unreasonably and vexatiously multiplying proceedings
  • Requires bad faith
  • Applies to attorney conduct specifically (not the party's substantive position)
  • § 285 applies to the party's case
  • § 285 vs.

Inherent Power

  • Courts can award fees under inherent power for bad faith litigation
  • High standard
  • Rarely used when § 285 is available

Fee Award Amount

  • The prevailing party is entitled to REASONABLE attorney's fees
  • Courts use a lodestar analysis: reasonable hours × reasonable hourly rate
  • If only part of the case was exceptional, fees limited to that part
  • ENHANCED DAMAGES vs.

Fees

  • § 284 enhanced damages: up to 3× compensatory damages for willful infringement (Halo Electronics, S.Ct. 2016)
  • § 285 fees: reimbursement of attorney's fees
  • Both can be awarded in the same case for the same conduct

Interest

  • § 284 also allows pre-judgment and post-judgment interest
  • Interest on damages separate from fees

Insurance Implications

  • Many defendants have patent infringement insurance
  • Insurance typically covers compensatory damages but may not cover § 285 fees
  • § 285 exposure is personal to the entity, not necessarily insured.
