He has represented some of the world’s largest and most successful technology companies, including Cisco, Intel, NEC, Verizon and many others. He has earned a reputation for crafting cutting-edge, innovative legal solutions and explaining highly complex technical information to juries and judges across the country. 

Patrick’s patent litigation practice covers technologies ranging from microprocessor architecture, circuitry and manufacturing processes to medical device technology. He has litigated patent cases in courtrooms in New York, California, Texas, Delaware, Virginia, Ohio, and Arizona. Patrick is recommended by The Legal 500 for patent litigation.

In the commercial litigation and arbitrations area, Patrick has represented such clients as JPMorgan Chase, Goldman Sachs, Elpida and Xilinx in litigations and complex disputes arising under the federal antitrust laws, ERISA, and RICO.

Patrick is passionate about social justice and the rights of the wrongfully sentenced.  He is recognized as a leader in the Firm’s pro bono practice, and has been honored by numerous organizations for his successful pro bono litigation victories. He led the Firm’s partnership with the Northern California Innocence Project at Santa Clara University to petition for habeas on behalf of a client who spent 30 years in state custody for a crime that another man confessed to. The Superior Court of California, County of Alameda granted the habeas after the Alameda District Attorney chose not to oppose.  He also led the Firm’s partnership with the Law Foundation of Silicon Valley to bring claims on behalf of the California Association of Mental Health Patients' Rights Advocates against the California Department of Social Services and various California state officials.  On the eve of trial, the state agreed to a settlement that resulted in a substantial rewrite of several California regulations that greatly expanded access to state-licensed housing for elderly adults with mental health disabilities.

Shortly after Simpson Thacher established its Silicon Valley practice in 1999, Patrick joined the litigation team in the Palo Alto office.  Prior to that, he practiced for three years in the Firm’s New York office and two years in the Hong Kong office.  His knowledge of international law and arbitration is highly valued by his global clients. Patrick is co-chair of the Corporate Information Governance Committee of the International Bar Association and is a member of the IBA’s Technology Law and Litigation Committees.

Patrick received his undergraduate degree from Dartmouth College and his J.D. from Columbia Law School, where he was a Harlan Fiske Stone Scholar.
