Traffic Control Patent Battle Ends with $343K Fee Award Against Site 2020

In a decisive conclusion to nearly four years of patent litigation, the U.S. District Court for the District of Montana awarded Superior Traffic Services, LLC over $343,000 in attorney fees and costs against plaintiff Site 2020 Incorporated — a striking outcome that underscores the high-stakes risk patent holders face when pursuing infringement claims that ultimately cannot sustain judicial scrutiny. Chief Judge Dana L. Christensen adopted Magistrate Judge DeSoto’s Findings and Recommendations in full, overruling Site 2020’s objections and granting the fee award under 35 U.S.C. § 285, the patent statute’s “exceptional case” provision.

The case — Site 2020 Inc. v. Superior Traffic Services, LLC, No. 9:21-cv-00063 — centered on traffic control technology patents, specifically automated flagger assist devices (AFADs) used in roadway work zones. For patent attorneys, IP professionals, and R&D teams operating in the intelligent transportation and traffic management space, this case delivers critical lessons about litigation risk, fee-shifting exposure, and the procedural dangers of overreaching infringement assertions.

Case Overview

The Parties

The Patents at Issue

Two U.S. patents were asserted in this litigation, both relating to automated traffic control systems (AFADs) used in roadway work zones:

• • U.S. Patent No. 10,249,186 B2 — Systems and methods for remotely controlling flagger-assist devices.
• • U.S. Patent No. 11,055,993 B2 — Further advancements in automated traffic control systems.

The Accused Products

Site 2020 targeted Superior Traffic’s **PTS (Portable Traffic Signal), AFAD (Automated Flagger Assist Device), and TESS (Traffic Entry Safety System)** product lines — the core of Superior Traffic’s field operations business.

Litigation Timeline & Procedural History

Filed on May 21, 2021, in the U.S. District Court for the District of Montana, this case ran for 1,441 days before closing on May 1, 2025 — nearly four years of active litigation. The Montana venue was notable; federal patent cases in this district are comparatively rare, and the assignment to Chief Judge Dana L. Christensen, a well-regarded senior jurist with broad federal jurisdiction experience, added procedural gravitas.

Key procedural milestones included Superior Traffic’s filing of a Motion for Attorney Fees and Costs (Doc. 141) and a Motion to Voluntarily Dismiss Counterclaims Without Prejudice (Doc. 148). The case proceeded through Magistrate Judge DeSoto’s Findings and Recommendation (Doc. 167), which Site 2020 objected to — objections that Chief Judge Christensen ultimately overruled in their entirety, adopting the magistrate’s recommendations in full. The case’s resolution came through voluntary dismissal of the underlying claims rather than a jury verdict, with fee adjudication as the final contested battleground.

The Verdict & Legal Analysis

Outcome

The court’s final order delivered a multi-part ruling with significant financial consequences:

• • Site 2020’s objections to Magistrate DeSoto’s Findings and Recommendation were overruled in full.
• • Superior Traffic’s Motion to Voluntarily Dismiss Counterclaims was granted without prejudice.
• • Superior Traffic’s Motion for Attorney Fees was granted in part and denied in part, with a total award of approximately $343,193.31. This included $315,464.50 for Category 1 fees, $4,041.06 for Category 1 costs, and $23,687.75 for fees incurred litigating the fee motion itself.

Verdict Cause Analysis

The fee award under 35 U.S.C. § 285 is only available in cases the court deems “exceptional” — typically where litigation conduct was unreasonable, the claims were objectively weak, or the case was pursued for improper purposes. The court’s grant of Category 1 fees signals a judicial determination that some portion of Site 2020’s litigation conduct crossed the threshold for exceptional case treatment.

The fees-on-fees award of $23,687.75 is particularly instructive. Courts are not obligated to award fees for litigating fee motions, and this additional grant suggests the court found Superior Traffic’s fee motion itself to be reasonably and necessarily pursued — strengthening the overall narrative that Site 2020’s litigation posture was problematic.

Legal Significance

The § 285 exceptional case analysis in this case will serve as regional precedent within the District of Montana for traffic technology and industrial automation patent disputes. The bifurcated fee structure — granting some categories while denying others — illustrates that courts apply granular scrutiny to fee applications rather than an all-or-nothing standard. Patent litigators should note that Octane Fitness, LLC v. ICON Health & Fitness, Inc. (2014) lowered the exceptional case threshold; this ruling is consistent with that more permissive standard.

Industry & Competitive Implications

The automated flagger assist device market sits at the intersection of infrastructure safety regulation and patent-protected automation technology. As OSHA and state DOTs continue pushing for reduced human exposure in active work zones, AFAD technology adoption is accelerating — and with it, the patent assertion activity targeting market entrants.

This case signals that patent assertion entities or competitors entering this space with aggressive infringement claims face real fee-shifting risk if their claim mapping is weak or their litigation conduct unreasonable. For traffic control contractors like Superior Traffic, the outcome validates investment in strong IP defense counsel even in niche technical markets.

The involvement of Greenberg Traurig — a Tier 1 national IP litigation firm — defending a regional traffic services company speaks to the growing sophistication and cost of patent disputes in industrial automation verticals. Companies operating flagger-replacement systems, automated work zone management platforms, or remote traffic control devices should monitor the ‘186 and ‘993 patent families for continuation applications and related assertion activity.
