In a recent nonprecedential decision, the Federal Circuit affirmed a district court ruling ordering the correction of inventorship for U.S. Patent No. 9,376,049. Tube-Mac Indus., Inc. v. Campbell, No. 2022-2170 (Fed. Cir. Mar. 15, 2024). The patent at issue, originally naming a single inventor (Steve Campbell), claims a lightweight intermodal container system for transporting refrigerated gaseous fluids.
This post examines the reasoning behind the Federal Circuit's affirmance as well as the potential applicability of the equitable defense of laches in cases brought under 35 U.S.C. § 256 to correct inventorship on an issued patent.
