## Molekule Wins Legal Victory: Air Purifier Trademark Dispute Resolved in Court

Molekule Group, Inc. (Nasdaq: MKUL) achieved a significant legal triumph as a federal court dismissed a trademark infringement lawsuit with prejudice, clearing the path for the air purification technology company to continue advancing its market position without legal encumbrance.

### The Lawsuit and Its Resolution

The dispute originated when Sterilumen, Inc.—a subsidiary of Applied UV—filed suit against Molekule in August 2022 in U.S. District Court for the Southern District of New York. Sterilumen sought $20 million in damages, alleging trademark infringement and unfair competition practices. The case bore the designation 7:22-cv-06842-PMH.

Rather than accepting these claims passively, Molekule mounted a robust defense and filed counterclaims that challenged the validity of Sterilumen's trademark rights. The company simultaneously sought damages for what it characterized as fraudulent registration. This aggressive posture proved instrumental in shaping the eventual outcome.

On March 13, 2023, the presiding judge sided decisively with Molekule. The court issued an order dismissing all claims against the air purification company with prejudice—a legal term meaning the charges cannot be refiled. Following this ruling, Molekule and Sterilumen reached a settlement agreement whereby Sterilumen agreed to abandon its appeal rights and relinquish further pursuit of its claims against Molekule's trademarks, including SteriductTM and AerocleanTM.

### Strategic Significance for Molekule Air Purifier Operations

The dismissal carries weight beyond mere legal vindication. By prevailing without financial compensation to the plaintiff and having legal costs absorbed by insurance coverage, Molekule preserved resources while protecting its brand integrity—critical assets for any air purifier manufacturer operating in competitive markets.

Jason DiBona, serving as CEO, characterized the outcome as validation of the company's professional standards. "We are very pleased with the favorable resolution of this matter and along with it the affirmation of the professionalism of our sales and marketing practices," DiBona stated. He reiterated the organization's primary focus: scaling operations and fulfilling its core mission to deliver clean indoor air solutions globally.

### Molekule's Product Portfolio and Market Position

The company markets a comprehensive range of FDA-cleared air purification devices engineered for diverse indoor environments. Its product lineup includes the Air Pro, Air Mini+, and Pūrgo™ systems, each designed for deployment in residential, commercial, healthcare, and educational settings. The breadth of this portfolio positions Molekule as a comprehensive provider within the air purification sector.

Beyond hardware, Molekule integrates software capabilities to help consumers and professionals monitor and optimize indoor air quality—a dual approach that differentiates the company in increasingly health-conscious markets.

### Looking Forward

With the air purifier lawsuit resolved favorably and trademark rights secured, Molekule enters its next phase focused on product innovation and market expansion. The legal clarity removes uncertainties that might have complicated strategic planning or partnership negotiations. The company's trajectory now depends primarily on execution capability and market demand for indoor air quality solutions rather than litigation outcomes.

For stakeholders and potential customers evaluating the Molekule air purifier ecosystem, the court's decision affirms the legitimacy of the company's brand and operational practices—factors that increasingly influence purchasing decisions in the health technology space.
