Matthew Ritter

Matthew litigates complex intellectual property matters across multiple forums including federal district court, the US International Trade Commission and proceedings before the US Patent and Trademark Office. He represents clients in high-stakes disputes involving cutting-edge sectors including semiconductor device design and manufacture, consumer electronic devices, software, video coding, mobile devices and connected technologies.

With a background in electrical and computer engineering, Matthew brings a strong technical foundation and a global perspective to his work. Before joining Cooley, he practiced at a global intellectual property boutique firm, where he handled sophisticated patent and IP disputes for innovative technology companies located in the US and overseas. His experience spans the full life cycle of IP enforcement and defense, from early‑stage strategy and administrative proceedings to high‑stakes litigation. 

Matthew has hands-on litigation experience at every stage of federal district courts cases and ITC investigations, including depositions, expert witness preparation, expert reports, and trial. He regularly works with technical experts to develop invalidity and non-infringement positions, and with economics experts to develop damages and domestic industry defenses. Matthew consistently translates and simplifies complex technical concepts to judges, juries and fact finders at all stages of litigation.  

In law school, Matthew was a student associate in the Indiana University Maurer School of Law’s Intellectual Property Law Clinic, representing clients on intellectual property matters and serving as an editor for IP Theory. He deepened his understanding of IP protection in a global context by working internationally as a Milt Stewart Fellow in Cambodia, assisting clients with corporate compliance, labor regulatory issues, and intellectual property enforcement.
