ITC Section 337 Proceedings



With technical depth and high-stakes IP litigation experience, we provide strategic and comprehensive counsel to help our clients successfully navigate the fast-paced proceedings of the United States International Trade Commission (ITC).

Our Approach

Many global IP disputes include Section 337 investigations at the ITC. Sophisticated companies with complex, technical, and “bet the company” IP disputes are choosing the ITC’s accelerated proceedings and broad remedial orders as an effective alternative or complement to U.S. District Court litigation.

Because Section 337 investigations typically advance to trial in about eight to ten months, the results can significantly influence a business’s bottom line, supply chain, or even its continued existence. Consequently, it is pivotal to hire a trial-ready team that understands the unique and complex ITC procedures and technical issues of Section 337 litigation.

We have represented both complainants and respondents in Section 337 investigations across a spectrum of industries including LED lighting, consumer electronics and products, automotive, and computer software and hardware in matters involving all forms of IP. Our dedicated ITC team has extensive knowledge and experience navigating all aspects of Section 337 investigations. We are one of the first law firms to represent a university as a sole ITC complainant. Our success litigating at the ITC is a result of our deep understanding of the ITC’s procedural rules, body of law, evidentiary hearings, and administrative law judges.

Our lawyers have also coordinated representations in parallel proceedings when investigations involve concurrent litigation in federal district courts or post-grant proceedings before the Patent Trial and Appeal Board.

Our core ITC team includes IP attorneys, patent agents, technical specialists, and PhD-qualified research scientists and practitioners with backgrounds working in the technology industry. Our collective experience provides the foundational knowledge necessary to strategically staff every type of IP issue that involves a Section 337 investigation.
