Sean Cunningham focuses on patent litigation, in particular complex patent litigation involving multiple parties, patents and jurisdictions. He has extensive experience handling patent cases through trial in district courts and in the International Trade Commission (ITC).

Sean has represented Fortune 100 technology companies in a number of patent trials, including five jury trials, in the past 10 years. Most recently, he participated in a two-week bench trial in the ITC (Hewlett-Packard v. Acer Computer, in early 2008) and a two-week jury trial in the Northern District of New York (Cornell v. Hewlett-Packard, in mid-2008), which was presided over by Federal Circuit Court of Appeals Judge Randall Rader sitting by designation. That case also involved a three-day bench trial at the Federal Circuit on various equitable defenses, which is believed to be the first evidentiary hearing ever held at the Federal Circuit.
