Columbia Insurance Co. v. Simpson Strong-Tie Company Inc.

Background

Columbia Insurance Company and MiTek Inc. alleged that Simpson Strong-Tie Company Inc. infringed U.S. Patent No. 11,920,339, known as the ’339 patent, under 35 U.S.C. § 271. MiTek is identified as Columbia’s exclusive licensee. The patent concerns a method of constructing a fire-resistive wall assembly using hangers that connect structural components, such as beams and joists, to fire-separation walls.

Simpson filed a counterclaim seeking a declaratory judgment that the relevant patent claims are invalid. It also filed a petition asking the Patent Trial and Appeal Board (PTAB) to institute post-grant review (PGR), a proceeding that can examine the validity of a recently issued patent. Simpson moved to stay the district-court case while the PTAB considered whether to institute PGR and, if it did so, while the PGR proceedings continued.

Legal standard

The court explained that district courts have discretion to stay a case while patent validity proceedings are pending. It considered three factors: the stage of the litigation, whether a stay would simplify the issues, and whether a stay would unfairly prejudice the party opposing it. In evaluating prejudice, the court considered the timing of the patent-review request and stay motion, the status of the review proceedings, and the relationship between the parties.

Analysis

The court found that the first factor favored a stay because the case was in its earliest stages. The parties had exchanged initial disclosures, but neither side had served discovery, and trial was not scheduled until June 2026.

The court found that a stay would likely simplify the case. It considered the PTAB likely to institute PGR based in part on its institution of earlier review proceedings involving closely related patents. If review were instituted, the PTAB could invalidate some or all of the ’339 patent claims, narrowing the issues for the district-court case. The court acknowledged that the ’339 patent contains method claims not present in the earlier patents, but found those claims closely related to the earlier apparatus claims.

The court also found that the timing of Simpson’s review petition and stay motion favored a stay: Simpson filed the petition before the applicable nine-month deadline and filed the stay motion the same day. The fact that the PTAB had not yet decided whether to institute review weighed against a stay, but the court considered the broader status of related patent proceedings to favor waiting for additional clarity.

The relationship between the parties weighed against a stay because they were direct competitors and the alleged marketplace harms, including diminished market recognition and price erosion, might not be fully compensable with money damages. The court nevertheless concluded that this risk was not substantial enough to outweigh the other factors favoring a stay.

Disposition

The court granted Simpson’s motion to stay the case pending the PTAB’s institution decision and, if PGR was instituted, through resolution of those proceedings or further order of the court. Simpson was ordered to notify the court of the PTAB’s institution decision within seven days after that decision. The court did not decide whether the ’339 patent was valid or whether Simpson infringed it.
