Notable Matters

  • In defending a major bank sued by the largest patent owner in the world, we successfully invalidated three of the four asserted patents; a later motion filed by our firm resulted in the dismissal of all claims on the fourth patent.
  • We successfully represented a New York-based company in a Digital Millenium Copyright Act case. Although we were hired after the court had already entered an injunction against our client, we successfully argued the facts of the case and the court not only dissolved the injunction but granted summary judgment in favor of our client.
  • Dontzin Nagy & Fleissig regularly represents one of the largest art galleries in the world in all of its copyright and trademark disputes. We have obtained judgments in our client’s favor both in the U.S. and overseas.
