Background
The U.S. International Trade Commission (ITC) previously determined that Cartessa Aesthetics, LLC, had infringed a patent belonging to Hydrafacial LLC, violating 19 U.S.C. § 1337. The ITC issued a remedial exclusion order but suspended its enforcement because the patent was set to expire on March 29, 2026.
Following the patent’s expiration, Cartessa appealed to the Federal Circuit. Cartessa filed a motion to consolidate its appeals, dismiss them as moot (no longer a live controversy), and vacate the ITC’s final determination against it. The ITC did not oppose Cartessa’s motion.
However, Hydrafacial, the patent holder and intervenor in the case, opposed the motion to vacate. Hydrafacial argued that the ITC’s decision should stand because it could have “collateral consequences” in separate, ongoing proceedings before the U.S. Patent and Trademark Office (PTO) concerning related patents.
The Court’s Holding
The Federal Circuit granted Cartessa’s motion in full. The court dismissed the appeals as moot, vacated the ITC’s final determination, and remanded the case to the ITC with instructions to dismiss the entire investigation.
The court reasoned that an appeal of an ITC decision becomes moot once the patent at issue has expired. This is because the ITC can only grant prospective relief (like an exclusion order blocking future imports), and such relief is impossible once patent rights have ended. The court noted its routine practice of vacating the ITC’s underlying decision when mootness arises from “happenstance,” such as a patent’s expiration, rather than the strategic actions of the parties.
Critically, the court rejected Hydrafacial’s argument about potential consequences at the PTO. It held that the possibility of an ITC decision having a persuasive or “stare decisis” effect on a different agency does not create a legally cognizable interest sufficient to keep a case alive. The court found Hydrafacial’s assertions about the PTO proceedings were not “concrete” and that any potential benefit from the ITC decision in that venue was too “indirect” to defeat mootness.
Key Takeaways
- An appeal of an ITC Section 337 decision generally becomes moot when the underlying patent expires, as the ITC’s remedial powers are prospective only.
- When an ITC appeal becomes moot due to happenstance, the Federal Circuit will typically vacate the ITC’s final determination, effectively wiping the decision off the books.
- The potential for an unreviewed ITC decision to influence separate proceedings at the U.S. Patent and Trademark Office is not a sufficient “collateral consequence” to prevent a case from being found moot.
- A party arguing against mootness must show a concrete and legally cognizable interest in the outcome, not just a speculative or indirect benefit in another forum.
Why It Matters
This per curiam order reinforces a key procedural rule at the Federal Circuit: a patent’s expiration during an ITC appeal will generally lead to the vacating of the underlying infringement finding. The ruling clarifies that the fight ends when the patent expires, and the unreviewed ITC decision cannot be used as a sword or shield in other legal venues, such as parallel validity challenges at the PTO.
For intellectual property litigators, this decision underscores the importance of the appellate timeline in ITC cases. It confirms that an ITC victory is vulnerable if the patent expires before the appeal is resolved, preventing patent holders from leveraging those wins in other disputes. This practice ensures that only decisions that can be fully reviewed by the courts retain their legal force, preventing potentially erroneous, unreviewed agency findings from having lingering prejudicial effects.
