Jeremiah W. Nixon

Jeremiah W. Nixon is a patent litigator at The Simon Law Firm, with a practice that also encompasses class actions, complex business disputes, data privacy, and antitrust law. He is recognized for representing plaintiffs in high-stakes litigation, with his patent work falling under the firm's broader intellectual property and commercial litigation practice.

Nixon primarily represents plaintiffs in patent matters, having four plaintiff-side appearances compared to two defendant-side appearances in the tracked cases. His notable patent litigation experience includes representing Midwest Energy Emissions Corp. in several infringement lawsuits related to mercury emissions reduction technologies (SEA Technologies®) for coal-burning power plants. These cases, including Midwest Energy Emissions Corp. et al. v. Ameren Corp. et al. and Midwest Energy Emissions Corp. et al. v. Evergy, Inc. et al., involve allegations of knowing patent rights violations by major utility companies. A related case led by different counsel resulted in a $57 million patent infringement verdict for Midwest Energy Emissions Corp. in 2024.

He also appeared as Pro Hac Vice Counsel on the defendant side in Unified Patents v. Ginko LLC, a case that likely involves a challenge to Ginko LLC's patent, possibly related to data sharing technology (e.g., Apple iPhone and Watch features). This engagement suggests experience with inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB), as Unified Patents is known for its IPR challenges.

Jeremiah W. Nixon is admitted to the State Bar of Missouri and the State Bar of Illinois. He is also admitted to practice in the U.S. District Court for the Eastern District of Missouri, the U.S. District Court for the Northern District of Illinois, and the U.S. District Court for the Southern District of Illinois. He was recognized by Best Lawyers: Ones to Watch in America for Litigation – Intellectual Property in 2026. Prior to joining The Simon Law Firm, he practiced at a large St. Louis firm, where he handled business litigation for both plaintiffs and defendants, and at a complex litigation firm in Chicago focusing on plaintiff-side class actions. He also served as a prosecutor in the St. Louis Circuit Attorney's Office.
