Ronald M. Daignault
  • Experience

    Ron has almost thirty years of experience as an intellectual property litigator and trial attorney. He has represented clients in patent, trademark, false advertising, trade secret, and copyright cases across a broad spectrum of industries in district courts throughout the country and before the ITC. Ron currently represents patent-owners in litigations covering a variety of technology areas, and is widely respected as a pharmaceutical Hatch-Waxman litigator for generic drug companies. 

    Ron has been lead counsel or second-chair in over fifteen bench and jury trials and evidentiary hearings, and has argued before several U.S. Courts of Appeals, including various occasions in the Federal Circuit, and the New York Appellate Division. 

    With almost thirty years of experience, Ron understands that what he ultimately provides to clients is peace of mind. Creative, strategic, and meticulous, Ron builds longstanding collaborative relationships.

    Ron’s trial-tested courtroom skills underlay all parts of his practice, but he is also committed to working with clients to develop cost-effective strategies for results that make sound business sense — whether a client achieves those results inside or outside the courtroom. Ron believes in efficient case management to achieve the favorable outcome that best aligns with his client’s long-term strategies.

    In addition to his intellectual property litigation practice, Ron counsels startups and companies of all sizes regarding patent procurement and clearance, and domestic and international trademark prosecution and licensing. He has represented a pro bono client in connection with a New York State post-conviction criminal proceeding and federal habeas corpus petition. Ron also writes and speaks frequently on topics in the field of intellectual property, and is an advisory board member of Bloomberg/BNA’s Life Sciences Law and Industry Report.
