John is presently on a leave of absence.


ohn T. Battaglia is a seasoned trial lawyer with a record of dozens of jury trial wins and appellate victories. John was appointed as Deputy Associate Attorney General of the United States Justice Department by the administration of President George W. Bush. 

At Fisch Sigler alone, John has represented clients across a diverse set of technologies. Just starting with the letter A, his range of work spans from ABB Corporation (mechanical) to (electrical) to Amneal Pharmaceuticals (chemical). John also represents companies whose names start with a letter other than "A."

John remains a recognized authority on jury trial strategy and presentation. John was selected and has served for more than a decade as a faculty member and trial instructor at the University of Virginia Law School's Trial Advocacy College. Recently, the College selected John as one of three recipient of its Justice William Brennan Award, bestowed on those who have demonstrated "outstanding skills as trial lawyers or as members of the judiciary" and for "their outstanding contributions to advocacy education and to the legal profession." John joined an august group of past recipients, including Justice Brennan, Justice Scalia, David Boies and Ted Wells. John has also served as long-term faculty at the National Institute for Trial Advocacy (NITA), and teaches at several law schools on both patent law and trial advocacy.

John has also been repeatedly named an "IP Star" in the most recent Managing IP magazine IP World Handbook and Survey, including its most recent listing. Likewise, John has been also selected for inclusion in the most recent edition of the Expert Guides: World's Leading Litigation Lawyers, including its most recent edition. John has also been repeatedly named to the SuperLawyer's annual listing.

John is also an accomplished appellate advocate, having argued many federal appeals across the country. His wins include cases in the United States Courts of Appeal for the Federal Circuit, as well as the Second, Sixth, Seventh, and Ninth Circuits. John, for example, argued Papst Licensing v. Fuji Film, the Federal Circuit's first application of the Supreme Court's decision in Teva v. Sandoz. For that victory, Law360 dubbed him and the Fisch Sigler team a "Legal Lion." The resulting Papst opinion has already been cited over 250 times in this short time.

John clerked for the Honorable Paul R. Michel of the United States Court of Appeals for the Federal Circuit, and the Honorable William T. Prince of the United States District Court for the Eastern District of Virginia. John also served as a trial lawyer and federal prosecutor with the United States Department of Justice, where he was selected for the DOJ's prestigious and highly selective Honors Program.

In between his periods of government service, John was previously a partner at Finnegan Henderson Farabow Garrett & Dunner LLP and Kirkland & Ellis LLP.
