Post-Trial Procedures in Patent Litigation
Patent litigation doesn't end with the verdict. After a trial, parties can file motions to challenge outcomes or seek additional relief. These post-trial procedures can significantly impact the final resolution of a patent dispute, sometimes even overturning the jury's decision entirely.
This section covers the main post-trial motions, two important doctrines that shape post-trial outcomes (inequitable conduct and willful infringement), and the remedies and appeals available after trial.
Post-Trial Motions
Post-trial motions are filed after the verdict and give parties a chance to challenge the outcome or request additional relief before (or instead of) going to appeal. Three motions come up most often:
- Motion for Judgment as a Matter of Law (JMOL): This argues that no reasonable jury could have reached the verdict based on the evidence presented. If the court grants it, the jury's verdict is overturned. Think of it as saying, "The evidence was so one-sided that the jury got it wrong as a matter of law."
- Motion for a New Trial: This asserts the trial was unfair because of errors, misconduct, or newly discovered evidence. If granted, the whole trial starts over.
- Motion for a Permanent Injunction: This asks the court to prohibit the infringing party from continuing its infringing activities going forward. Courts evaluate four factors before granting one: (1) irreparable harm to the patent holder, (2) inadequacy of monetary remedies, (3) balance of hardships between the parties, and (4) whether the public interest favors an injunction.
Beyond challenging the verdict itself, post-trial motions also serve a strategic purpose: raising issues at this stage preserves them for appeal. If you don't raise a problem in a post-trial motion, you may lose the right to argue it later.
Proving Inequitable Conduct
Inequitable conduct is a defense raised by the accused infringer. It alleges that the patent holder acted improperly during the patent prosecution process (the back-and-forth with the USPTO to get the patent granted). For example, the applicant may have withheld a key piece of prior art that would have changed the examiner's decision.
To prove inequitable conduct, the accused infringer must establish two elements:
- Materiality: The information that was withheld or misrepresented was material to patentability. In other words, it would have influenced a reasonable patent examiner's decision to grant the patent.
- Intent to deceive: The patent applicant or their representative acted with specific intent to deceive the USPTO. Intent can be inferred from circumstantial evidence, but it must be the single most reasonable inference from the facts. A mere oversight or negligent omission is not enough.
Both elements must be proven by clear and convincing evidence, which is a high burden of proof (higher than the typical "preponderance of the evidence" standard in civil cases).
The consequences are severe. If inequitable conduct is proven, the entire patent is rendered unenforceable, even if only some claims were affected by the misconduct. On top of that, the patent holder may face additional penalties such as attorney's fees and potential antitrust liability.
Criteria for Willful Infringement
Willful infringement occurs when an infringer knowingly or recklessly disregards the patent holder's rights. It matters because it can dramatically increase the financial consequences for the infringer.
Courts look at two main criteria:
- Knowledge of the patent: The infringer had actual knowledge of the patent, or was willfully blind to its existence.
- Lack of a reasonable basis: The infringer lacked a good-faith belief that their actions did not infringe the patent or that the patent was invalid. Obtaining an opinion of counsel can help establish good faith, but it's not required.
Willful infringement must be proven by clear and convincing evidence, and the determination is at the court's discretion based on the totality of the circumstances.
If willful infringement is found, two major consequences can follow:
- Enhanced damages: Under 35 U.S.C. § 284, the court may increase damages up to three times the amount originally assessed. Courts consider factors like the egregiousness of the infringer's conduct, how long the infringement lasted, and whether the infringer took any remedial action.
- Attorney's fees: Under 35 U.S.C. § 285, the court may award reasonable attorney's fees to the prevailing party in "exceptional cases." A case qualifies as exceptional when it stands out due to the weakness of a party's litigating position or the unreasonable manner in which the case was litigated.
Post-Trial Remedies and Appeals
Once the trial and post-trial motions are resolved, the court's final judgment typically includes one or more remedies:
- Injunctions: A permanent injunction can prohibit the infringer from making, using, or selling the infringing product going forward. As noted above, courts apply a four-factor test before granting one.
- Damages: Monetary compensation awarded to the patent holder. This can include lost profits or a reasonable royalty, and may be enhanced up to three times in cases of willful infringement.
- Appeals: The losing party can appeal the trial court's decision to a higher court. For patent cases, appeals from federal district courts go to the U.S. Court of Appeals for the Federal Circuit, which has exclusive jurisdiction over patent appeals. The appellate court reviews questions of law but generally defers to the trial court's factual findings.
