Patrick has honed his trial skills in courtrooms across the country, and spent his early career working alongside renowned trial lawyers, like Ronald J. Schutz. He has since tried a wide range of cases, including patent infringement, breach of contract, personal injury, and felony-criminal defense cases. In 2021, he served as lead trial counsel in a personal injury case wherein his team secured a $27.8 million jury verdict on behalf of Dr. Richard Tholen, a top Twin Cities plastic surgeon, who endured an amputated leg after Assist America refused to evacuate him for proper medical care. This verdict has been reported as the largest personal injury verdict in Minnesota history. In 2020, he secured a complete victory in an arbitration for celebrity chef, Chloe Coscarelli, and her business entity that restored her 50% ownership in the “by Chloe” restaurant company she founded and was previously valued in excess of $60 million; enjoined the company from selling retail products; and awarded Chloe a $2.2 million in attorneys’ fees and costs. He also obtained a final judgment in excess of $2 million in favor of his client following a jury verdict against a former employee accused of misappropriating confidential information. In 2016, he tried a breach of license dispute over unpaid royalties, and obtained a $5.7 million verdict that settled on appeal for $13.5 million. Many of Patrick’s cases have resolved successfully before trial, driven by his preparation and readiness for trial.
Patrick is also adept at handling high-stakes appeals. He has argued at the Eighth Circuit, Ninth Circuit, Federal Circuit, and Minnesota Supreme Court and Court of Appeals. In 2020, for example, Patrick obtained a reversal and remand from the Eighth Circuit in Tholen v. Assist America, in which Patrick also serves as trial counsel for Dr. Tholen in his defamation claim. In 2021, Patrick achieved a reversal and remand from the Minnesota Court of Appeals in Smits v. Park Nicollet, finding a triable issue in a wrongful death action over Park Nicollet’s duty to provide reasonable medical care to its mental health patient and his family.
Patrick is passionate about ensuring access to justice for all, not just those who can afford it. From 2015 through 2018, he chaired Robins Kaplan’s Pro Bono Committee. Under his leadership, The American Lawyer ranked the firm as having the fourth-best pro bono program in the country. Law360 and The National Law Journal, among other national publications, also recognized the firm’s program during his tenure. As chair, Patrick led by example. In 2017, he obtained what is reported to be the first-ever verdict in a civil sex tourism case; the jury awarded $950,000 to his client after finding that she had been sexually assaulted in Laos at the age of 14 by a 43-year-old U.S. citizen. He also serves as a Special Assistant Attorney General for the State of Illinois in the state’s suit against the City of Chicago for police misconduct and civil rights violations. The ABA recognized Patrick’s dedication to pro bono work by awarding him its prestigious Pro Bono Publico Award in 2018, and Public Justice named him one of four finalists for Trial Lawyer of the Year.

The district court then denied Apple's equitable defenses of laches and inequitable conduct following a bench trial, which Mr. Arenz tried as second-chair counsel.
