Biography

Erika’s practice centers on patent drafting and prosecution, with experience handling a broad mix of applications across software, large language models and machine learning, and medical devices. Erika began building her patent prosecution foundation in law school, spending two years as a Patent Law Clerk for a large IP boutique firm. Before entering the legal profession, she worked at the intersection of software and biotechnology, validating software and hardware for high-throughput, next-generation sequencing instruments.

Erika earned her Juris Doctor at Mitchell Hamline School of Law. During her time there, Erika gained hands-on patent experience working in the IP Clinic to assist low-income and small-entity inventors. She also served on the Editorial Board of Cybaris, an Intellectual Property Law Review, and published a paper on copyright issues surrounding video game modifications. She also competed in the Spring 2025 USPTO Patent Drafting Competition.

Erika earned her B.S. in Mechanical Engineering and Physics from Point Loma Nazarene University, her M.S. in Biomedical Engineering from Johns Hopkins University, and her Juris Doctor, cum laude, from Mitchell Hamline School of Law, where she also earned a Patent Law Certificate from the law school’s Intellectual Property Institute. Erika is registered to practice before the U.S. Patent and Trademark office.


Outside of her patent practice, Erika and her husband run a food blog and are always searching for new restaurants. She enjoys playing tennis, reading mystery and sci-fi thrillers, unwinding with video games, and taking care of her three cats and one dog.

    The Active Time Battle (ATB) system, first patented in 1995 for the Final Fantasy series, transformed RPG combat by blending turn-based strategy with real-time urgency. Instead of static turns, each character and enemy acted on their own timer, creating tension and encouraging quick, tactical decisions. This mechanic defined an era of role-playing video games and was a core feature of Final Fantasy VII, my favorite game of all time. Even though the patent has since expired, its influence lives on in countless modern titles.
