The Decision
The Federal Circuit issued its decision in mCom IP, LLC v. City National Bank of Florida on May 15, 2026.
The U.S. Court of Appeals for the Federal Circuit vacated an $85,000 attorney fee award previously granted to a patent defendant, narrowing the grounds on which courts can shift costs in intellectual property disputes. In the Mcom Ruling, the appellate court reviewed a patent dispute involving banking technology. The lower court had previously awarded fees to the defendant, concluding that the plaintiff's litigation position warranted a financial penalty. The Federal Circuit reversed course, holding that the existence of weak claims, pleading flaws, or unproven license theories are insufficient on their own to justify fee awards. This appellate intervention directly cancels the $85,000 sanction and resets the expectations for prevailing defendants.
Why It Matters
This ruling fundamentally alters the risk calculus for patent litigation across the country. Fee-shifting serves as a primary deterrent against frivolous patent infringement lawsuits, functioning as a mechanism to protect companies from the high costs of defending against meritless claims. By determining that weak claims and pleading flaws do not automatically trigger fee awards, the Federal Circuit provides patent plaintiffs with more latitude to pursue aggressive legal theories without the immediate fear of financial ruin. Defendants, conversely, face a higher burden when attempting to penalize plaintiffs for unsuccessful claims. The decision signals that appellate courts will require more than a weak case or an unproven license theory to classify a lawsuit as exceptional enough to warrant fee-shifting. Consequently, accused infringers must weigh the costs of defending a lawsuit knowing that recovering those costs at the end of the litigation will be significantly more difficult.
Who Should Care
For lawyers
Defense counsel representing accused infringers must adjust their post-litigation strategy. Requesting attorney fees will require demonstrating conduct that goes beyond mere pleading flaws or weak infringement theories. Lawyers will need to build a record of objectively baseless conduct or bad faith from the inception of the lawsuit. Plaintiff attorneys gain a measure of protection against fee-shifting motions, allowing them to advance novel theories without the immediate threat of financial sanctions if the claims ultimately fail. This protection extends to the drafting phase, where initial pleading flaws will no longer serve as a guaranteed anchor for a later fee motion.
For consumers and parties
Technology companies and financial institutions defending against patent infringement claims will find it harder to recover their legal costs, even if they defeat the lawsuit outright. For patent holders, the decision lowers the financial risk of enforcing intellectual property rights, meaning smaller inventors and non-practicing entities might be more willing to file lawsuits to protect their patents. Businesses that rely on the threat of fee-shifting to force early settlements from patent plaintiffs will lose a significant piece of their negotiating power.
Legal Background
In federal patent litigation, courts generally follow the American Rule, where each party pays its own legal fees regardless of who wins the lawsuit. However, federal law allows district court judges to award reasonable attorney fees to the prevailing party in exceptional cases. Historically, courts have looked at the substantive strength of a party's litigating position and the unreasonable manner in which the case was litigated to determine if a case meets this exceptional standard. Defendants frequently rely on early pleading flaws, weak infringement arguments, or unsupported licensing theories to argue that a plaintiff's case is exceptionally weak. Prior to the Mcom Ruling, some district courts interpreted these deficiencies as sufficient grounds to shift the financial burden to the losing plaintiff. This created an environment where patent plaintiffs faced a constant threat of paying the defendant's legal bills if their case collapsed during early motion practice or summary judgment.
What the Court Did
The Federal Circuit established a more difficult standard for patent defendants seeking to recover attorney fees. Reviewing the $85,000 fee award in the banking technology dispute, the appellate panel examined the specific justifications the lower court used to penalize the plaintiff. The court determined that the existence of weak claims, pleading flaws, or unproven license theories are insufficient on their own to justify fee awards. The appellate court concluded that while the plaintiff's arguments may have lacked merit or suffered from procedural defects, these common litigation shortcomings do not automatically elevate a case to the exceptional status required for fee-shifting. The Federal Circuit noted that penalizing parties for standard pleading flaws or weak claims would chill legitimate efforts to enforce patent rights. Consequently, the court vacated the financial penalty, firmly rejecting the notion that an unsuccessful legal theory equates to an exceptional case.
How It May Be Applied
District courts will now need to apply a stricter filter when evaluating post-judgment fee motions. Judges must look for evidence of bad faith, vexatious litigation tactics, or objectively baseless claims that go beyond standard pleading errors. An open question remains regarding how many combined flaws are required to cross the threshold into exceptional territory. If weak claims and unproven license theories are insufficient on their own, courts will have to determine whether a combination of these elements, paired with aggressive litigation tactics, might still justify an award. Patent defendants will likely attempt to pair arguments about weak claims with evidence of discovery abuses or other procedural misconduct to satisfy the Federal Circuit's elevated standard. Future litigation will test the boundaries of what constitutes an unproven license theory versus a completely fabricated one.
Standard for Fee Awards
| Legal Element | Previous Application | New Federal Circuit Standard |
|---|---|---|
| Weak Claims | Often cited as grounds for fee awards. | Insufficient on their own to justify fees. |
| Pleading Flaws | Used to demonstrate exceptional weakness. | Insufficient on their own to justify fees. |
| License Theories | Unproven theories supported fee-shifting. | Insufficient on their own to justify fees. |
| Defendant Burden | Required showing an exceptionally weak case. | Establishes a more difficult standard to recover fees. |
The Bottom Line
In the American legal system, parties usually pay their own lawyers. In patent disputes, judges can force the loser to pay the winner's legal bills if the lawsuit was exceptionally weak or handled poorly. The Federal Circuit's decision clarifies that simply having a weak argument, making mistakes in legal filings, or failing to prove a licensing theory is not enough to force a losing patent plaintiff to pay the defendant's attorney fees. This protects patent owners from severe financial penalties when they bring lawsuits that are ultimately unsuccessful but not entirely baseless.
