  • First-rate, first-chair trial lawyers: Few firms can match the depth and breadth of our first-chair trial lawyers and trial teams. Our IP litigators have successfully represented clients in some of the most hotly contested patent cases and other disputes in virtually every U.S. jurisdiction. We understand that every client has a unique IP case and approaches trials with a different view. Thus, we build long-standing relationships with our clients to expand our knowledge of their business and legal needs, as well as collaborate closely with in-house teams to develop a comprehensive trial approach to their IP disputes.
  • ITC Section 337 leader: Our experience litigating IP cases, combined with our insights into and knowledge of international trade law, allows us to secure effective resolutions for clients in complex International Trade Commission (ITC) Section 337 proceedings. Over the past decade, our lawyers have represented complainants and respondents in more than 20 Section 337 investigations before the ITC, all of which have resulted in victories or favorable settlements for our clients.

  • Inclusion advocate: Sidley is committed to achieving greater diversity in the legal profession. Over the years, the firm has cultivated a strong relationship with ChIPs, a nonprofit organization whose mission is to advance and connect women in IP, technology, law, and government. We were also a participant in the inaugural “Law in Technology Diversity Collaborative,” a diversity program announced in early 2019 in which first-year law students split a summer internship between a Bay Area tech company and a law firm.
