Mr. Keyhani focuses his practice on patent and intellectual property litigation in federal courts where he exclusively practices.* He has been successful representing individuals and private and publicly held corporations in all phases of high-stakes and complex litigation from preliminary hearings through trial and settlement negotiations in patent, trade secret, copyright, trademark and unfair competition matters. Over the past decade, Mr. Keyhani has served as lead litigation and trial counsel in over sixty (60) cases in federal district and circuit courts throughout the United States.
