Crowell’s International Trade Group was also selected as Law360’s “2021 International Trade Group of the Year,” based in part on Katie’s recent ITC and Court of International Trade successes. Legal 500 recognized the ITC 337 Practice Group as a “Firm to Watch.” Her patent litigation experience in the ITC, district courts, and Federal Circuit also led her to being featured as one of the “Top 50 under 45” attorneys in IP Law & Business

Katie represents companies in intellectual property and trade disputes in a variety of industries, including polymers, solar, consumer electronics, automotive, railroad, and electrical fittings. She has been involved in all stages of IP litigation, from presuit investigations through trial and appeal.

Katie is also a seasoned appellate advocate before the United States Court of Appeals for the Federal Circuit, where she won eight of her nine patent appeals.

Prior to joining Crowell, Katie served in the U.S. Navy Judge Advocate General’s Corps, where she gained extensive trial and appellate experience and reached the rank of lieutenant commander in the U.S. Navy Reserve. Immediately after her naval service, Katie served as the law clerk for Chief Judge Andrew S. Effron of the U.S. Court of Appeals for the Armed Forces.
