Chase A. Cobern

(972) 628-3625

Chase A. Cobern is a lawyer and CPA with a passion for identifying, developing, and presenting clients’ legal arguments as clearly and persuasively as possible. He practices in MWM’s litigation group with an emphasis on appellate matters. An enthusiast for effective written advocacy, Mr. Cobern has led briefing efforts on high-stakes issues in every phase of civil litigation, from dispositive motions to review before the U.S. Supreme Court. He is also a seasoned oral advocate, having successfully argued appeals in both federal and state courts.

In Repifi Vendor Logistics, Inc. v. IntelliCentrics, Inc., No. 2021-1906 (Fed. Cir. 2022) (Opinion) (Oral Argument), Mr. Cobern authored briefs and presented oral argument that successfully persuaded an appellate court to invalidate a patent as ineligible under 35 U.S.C. §101 at the pleadings stage, resulting in early dismissal of costly patent litigation in the Eastern District of Texas.

In Stonewater Roofing, Ltd. Co. v. Texas Department of Insurance, 641 S.W.3d 794 (Tex. App.—Amarillo 2022) (Opinion) (Oral Argument pt. 1; pt. 2), Mr. Cobern authored briefs and presented oral argument that successfully persuaded an appellate court to reverse a lower court’s dismissal of constitutional challenges to a Texas statute under the First and Fourteenth Amendments. The appellate court not only reinstated the constitutional challenges but held that the challenged statute must face strict scrutiny on remand, rendering it presumptively invalid.

In AMS Sensors USA Inc. v. Renesas Electronics America Inc., No. 4:08-cv-00451 (E.D. Tex. 2021) (Article), Mr. Cobern served as lead associate on a trial team that secured a federal jury verdict of $85.9 million in damages for trade secret misappropriation and breach of contract. Mr. Cobern argued the jury charge and preserved and presented arguments on a range of legal issues throughout the two-week trial.

In Galderma Laboratories L.P. v. Teva Pharmaceuticals USA, Inc., No. 19-2396 (Fed. Cir. 2020) (Opinion), Mr. Cobern authored briefs that persuaded an appellate court to reverse an adverse judgment on the briefing alone, reviving an international pharmaceutical company’s patent protection and restoring its market leadership.

Outside the office, Mr. Cobern enjoys spending time with his wife, Rachel, and their three children (Nolan, Quinn, and Cal).
