{ Bio Portrait }

David Ludwig’s practice focuses on patent litigation and counseling in a wide range of industries, including electronics, pharmaceuticals, medical devices, and scientific instruments. He has also litigated cases pertaining to copyrights, trademarks, and administrative law. David is adept at all stages of litigation, having served as counsel in several district court trials and several appeals. Most recently, David argued before the Second Circuit Court of Appeals in the defense of a pro bono client’s First Amendment rights. He is also licensed to practice before the U.S. Patent and Trademark Office and has represented clients in multiple inter partes review and interference proceedings.

Clients and team members rely on David for his broad-based scientific expertise, deep knowledge of patent law, and sharp analytical skills. A student of physics and having spent over eight years working with experts in the chemical, medical, and biological arts, David can quickly understand and analyze a wide range of new technologies and associated patent rights. He is able to assess case merits and develop potent litigation strategy under tight time constraints, allowing clients to make timely strategic decisions in urgent situations.

While David is first and foremost a litigator, he is also trained in business and holds an M.B.A. David’s education and interest in business decision-making permits him to see beyond the mere legal issues facing clients to the business realities that must often take precedence. As a result, clients and team members have recognized David as a key asset in counseling clients on patent-related issues and strategy, leading David to be recognized by the Connecticut Law Tribune as a “New Leader in the Law.”

Experience

Representative Matters:

  • Served as appellate and trial counsel in obtaining a decision from the Federal Circuit Court of Appeals affirming a District of Delaware bench trial decision that the patents covering Zohydro® (hydrocodone extended-release capsules) and asserted against Axinn client Alvogen were invalid. The decision removed the patents as a barrier to Alvogen bringing its lower-cost generic product to market more than a decade before the patents were set to expire.
  • Defended DePuy Synthes (a Johnson & Johnson company) in a patent infringement action in the District of Massachusetts brought by a non-practicing entity. The technology pertained to DePuy Synthes’s spinal implant products. After obtaining dismissal of key claims and filing several inter partes review petitions against the asserted patents, the case settled on favorable terms.
  • Currently defending Samsung in the District of New Jersey in a patent infringement suit brought by Rensselaer Polytechnic Institute. The technology at issue relates to Samsung’s QLED television displays.
  • Obtained favorable decision from the Fourth Circuit Court of Appeals to enable Watson Laboratories (now Teva) to speed its generic version of Celebrex® to market. An earlier lower court decision had effectively barred Watson and others from bringing their drugs to market. The Fourth Circuit reversed and remanded, finding that Watson and another company were eligible to share in a period of 180-day marketing exclusivity on the launch of their generic versions of Celebrex® because a reissued patent was not part of the same “bundle of rights” as an original patent.
  • Defended Nautilus in a copyright, trademark, trade dress, and unfair competition (Lanham Act) case in the District of Connecticut regarding Nautilus’s Bowflex products. Obtained dismissal of all claims.
