Carbon Six Barrels v. Proof Research

Docket Number: 22-30772
Judge: Jennifer Walker Elrod
Opinion Date: September 29, 2023

Proof Research, Inc. and Carbon Six Barrels, LLC both manufacture carbon-fiber gun barrels. Proof entered the market first and obtained a trademark for the unique appearance of its barrels. When Proof found out that Carbon Six intended to begin manufacturing and selling similar-looking carbon-fiber gun barrels of its own, Proof responded with litigation. However, Proof did not file suit against Carbon Six but rather against McGowen Precision Barrels, LLC, Carbon Six’s sister company. McGowen then initiated separate proceedings to have Proof’s trademark canceled. McGowen was ultimately successful, and Proof’s trademark for its carbon-fiber gun barrels was canceled in 2021. On February 9, 2022, Carbon Six filed this lawsuit against Proof for defamation and violation of the Louisiana Unfair Trade Practices Act stemming from Proof’s efforts to register, renew, enforce, and defend its previously valid trademark. However, Carbon Six brought its claims after the one-year prescriptive period imposed by Louisiana law had run. On Proof’s motion to dismiss under Rule 12(b)(6), Carbon Six failed to convince the district court that any of its claims were timely. The district court also held that Carbon Six’s LUTPA claim was legally deficient.
The Fifth Circuit affirmed. The court held that all actions Carbon Six alleged Proof took were discrete rather than ongoing, and each began and ended more than a year before this lawsuit was filed. Carbon Six’s LUTPA claim is therefore prescribed. The court explained even if Carbon Six could do so, Proof’s attempt to enforce a later-invalidated trademark does not violate LUTPA.
