About DJ

Danielle (DJ) Healey has been litigating complex cases in federal courts, state courts, and agencies, and handling licensing, antitrust, mediation and arbitration matters for over 34 years. She has focused on patent litigation and related antitrust and tort claims since 1994.

Ms. Healey has tried cases in U.S. district courts, state courts, U.S. International Trade Commission, International Chamber of Commerce (arbitration), American Arbitration Association, NASD Arbitration Forum, and private arbitration. She has argued appeals in the Federal Circuit, Fifth Circuit and Fourth Circuit courts of appeals, as well as the Texas Supreme Court and Texas Intermediate Courts of Appeals. Ms. Healey has been actively involved in planning and executing multi-jurisdictional strategies involving courts in the U.S. and Europe, and administrative agencies (including reviews in the U.S. Patent and Trademark Office (USPTO), invalidity and declaratory judgment actions in Europe, and state regulatory matters). Ms. Healey has worked on patent and antitrust issues with the U.S. Federal Trade Commission (FTC), and has represented clients intellectual property related competition matters before the FTC, the European Union, and Texas state authorities.

Ms. Healey has been involved in negotiating patent licenses in the semiconductor and software industries, she has represented clients in dealing with obligations and licensing in standard-setting organizations, she has been general counsel to a standard-setting group, and she has litigated the substantive and anticompetitive effects of licenses in court, in arbitration, and in administrative agencies.

Ms. Healey has also been an active speaker and author on trade secret, patent extraterritorial liability, patent damages, IP related antitrust law, arbitration and mediation. She has been fortunate enough to have been recognized by industry polls and publications for her work.

Ms. Healey graduated from the University of Texas School of Law in 1985 with honors, and Brown University in 1982. Ms. Healey served as a law clerk to the Honorable James DeAnda of the U.S. District Court for the Southern District of Texas, from 1985-1987.

Ms. Healey was one of the founders of the Houston IP Inn of Court, has been active in the State Bar of Texas intellectual property committee, the Eastern District of Texas bar association, and community projects where she lives in the Houston area. Prior to opening Fish & Richardson’s Houston office, Ms. Healey was a partner in the patent litigation section of an international law firm, and previously was a partner in her own patent litigation boutique firm, as well as a national patent litigation boutique firm in Houston, Texas.

Prior to joining Fish & Richardson, Ms. Healey has spoken, participated as a panelist, and presented papers at multiple conferences each year since 1996, including for example, participating as a panelist on standard-setting and antitrust at the ABA antitrust section’s spring meeting in Washington, D.C., presenting on litigation of trade secret and patent claims at University of California-Berkeley’s advanced patent law seminar in San Jose, California, on re-examination strategy in litigation at George Mason University-University of Texas’s advanced patent law seminar at the USPTO, and on patent pools, standards, and unfair competition and antitrust, at the state bar of Texas seminars.
