K.C. Coastal LLC v. J&M Underground Engineering: Design Patent Infringement Case Settles in 156 Days

Case Overview

The Parties

The Patent at Issue

This case involved a design patent protecting the ornamental appearance of Utility Blox™ that shaped the modern construction and utility engineering industry:

• • USD0994144S — Ornamental design of Utility Blox™ modular block

Legal Representation

Plaintiff’s Counsel: Joseph Robert Englander, Joshua D. Curry, and Pedro Stefan Quintana of Lewis Brisbois Bisgaard & Smith LLP — a nationally recognized litigation firm with substantial IP practice capabilities.

Defendant’s Counsel: Maximillian Scott Matiauda and Oliver Alan Ruiz of Malloy & Malloy PA — a Florida-based IP litigation boutique with deep regional court familiarity.

Litigation Timeline & Procedural History

Filed on May 6, 2025 in the U.S. District Court for the Southern District of Florida, this first-instance matter proceeded at a notably efficient pace. The Southern District of Florida is a moderately active patent litigation venue, known for experienced federal judges managing complex commercial disputes.

The case resolved without proceeding to claim construction or trial. A Joint Notice of Settlement was filed as Docket Entry 66, prompting the Court to order both parties to submit a Joint Stipulation of Dismissal under Federal Rule of Civil Procedure 41 by November 9, 2025, with all pending motions denied as moot.

The 156-day duration from filing to closure reflects a pre-trial settlement pattern increasingly common in design patent disputes, where the visual comparison standard — applied under the ordinary observer test established in Egyptian Goddess, Inc. v. Swisa, Inc. — creates sufficient legal uncertainty to incentivize early negotiation rather than costly litigation through discovery and trial.

The Verdict & Legal Analysis

Outcome

This case closed via settlement on October 9, 2025. No judicial determination of infringement, validity, or damages was rendered. The specific settlement terms — including any financial consideration, licensing arrangements, or design-around commitments — were not publicly disclosed. The Court’s order reflects a clean, consent-based resolution consistent with Rule 41 voluntary dismissal practice.

Verdict Cause Analysis

The matter was brought as a design patent infringement action. Under U.S. design patent law (35 U.S.C. § 171), the holder of a design patent may assert rights against any party that makes, uses, sells, or offers for sale an article embodying a design that is substantially similar to the patented design in the eyes of an ordinary observer.

Key analytical considerations that would have shaped litigation strategy include:

• • Ordinary Observer Test: Would an ordinary purchaser of Utility Blox™ or a comparable modular construction block mistake the accused product for the patented design? This standard governs infringement analysis and often drives early settlement when visual similarity is apparent.
• • Claim Scope: Design patent claims consist almost entirely of drawings. The breadth of protection hinges on how distinctively ornamental the registered design is relative to prior art in the construction block space.
• • Validity Exposure: The defendant’s likely defensive posture would have included scrutiny of prior art in modular block design to challenge the patent’s validity — a standard counter-strategy in design patent cases.

Legal Significance

Although no precedential ruling was issued, this case reinforces several important principles:

• • Design patents in construction products are actively enforced. Companies holding registered ornamental designs in industrial and utility product categories are willing to litigate and invest in enforcement.
• • Early settlement is strategically rational in design patent cases where the ordinary observer test creates binary litigation risk — particularly when both parties face business disruption from prolonged discovery.
• • Southern District of Florida continues to serve as a viable and efficient forum for design patent enforcement in the construction and infrastructure sectors.

Strategic Takeaways

For Patent Holders:
Registering design patents (USD applications) for commercially significant product configurations — even in industrial categories like modular utility blocks — creates enforceable IP assets. Filing under 35 U.S.C. § 171 provides a cost-effective enforcement pathway with strong visual comparison standards.

For Accused Infringers:
Early case assessment should include a thorough prior art search to evaluate design patent validity and an honest ordinary observer analysis of the accused product. If design differentiation is feasible without commercial sacrifice, design-around strategies should be evaluated before litigation costs escalate.

For R&D Teams:
Before commercializing products in categories where competitors hold design patents, conduct a Freedom-to-Operate (FTO) analysis covering both utility and design patent registrations. Design patents are frequently overlooked in FTO searches that focus primarily on utility claims.
