Litigation Timeline & Procedural History
Timeline
| Complaint Filed | July 17, 2025 |
| Voluntary Dismissal Notice Filed | December 30, 2025 |
| Case Closed | January 5, 2026 |
Filed in the Western District of Texas, the case closed well before any substantive litigation milestones. This pre-answer posture is procedurally significant, as it is precisely what makes Rule 41(a)(1)(A)(i) self-effectuating dismissal available.
The court noted its reliance on In re Amerijet Int’l, Inc., 785 F.3d 967, 973 (5th Cir. 2015), confirming that a plaintiff’s notice under this rule “terminates the case in and of itself” without requiring court action — a clean procedural exit.
The Verdict & Legal Analysis
On December 30, 2025, Wolverine Barcode IP filed a Notice of Voluntary Dismissal Without Prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i). The court formally ordered the case closed on January 5, 2026. No damages were awarded. No injunctive relief was granted. Each party was ordered to bear its own costs, expenses, and attorney fees. All pending motions, if any, were denied as moot.
The critical consequence: dismissal without prejudice. Wolverine Barcode IP retains the legal right to refile against McDonald’s — or other defendants — asserting the same patent, subject to applicable statutes of limitations and any strategic recalibration.
This procedural posture suggests several possible strategic explanations, including progress in licensing negotiations, a portfolio or venue recalibration by the plaintiff, or a vigorous defensive posture signaled by McDonald’s counsel, Greenberg Traurig LLP.
The absence of any adjudication on the merits means no precedent was established regarding the validity or infringement scope of U.S. 9,280,689 B2. The patent remains valid, issued, and potentially assertable. For companies operating barcode-based offline transaction systems, this is an important distinction: the legal questions raised by this patent remain unresolved by any court.
