Collins J. Seitz, Jr.

Collins J. (“C.J.”) Seitz, Jr. is a founding partner of Seitz Ross Aronstam & Moritz LLP.  He is the former managing partner of Connolly Bove Lodge & Hutz LLP, a 100-attorney firm where for almost thirty years he litigated corporate, commercial, intellectual property, and trust cases in the Delaware courts.

C.J. has litigated several high-profile cases in the Delaware Court of Chancery, a non-jury court with an international reputation as the preeminent forum for resolving corporate and trust disputes.  His Court of Chancery practice has included litigating several billion dollar family trust disputes and “busted deal” cases.  By way of example, C.J. recently served as co-counsel for Vulcan Materials Company in its successful trial and appellate victories halting Martin Marietta Materials, Inc.'s takeover efforts. 

As part of a trial team, C.J. has conducted corporate/commercial hearings and trials before numerous courts throughout the United States including Delaware, Illinois, Michigan, New Jersey, New York, South Carolina, and Texas.  He, along with other attorneys at his former firm, represented Pfizer, Inc. as lead counsel in the successful defense of Pfizer’s Lipitor patents covering the largest selling pharmaceutical in the world.

He has also tried cases and successfully argued appeals in the Third Circuit in various governmental matters, including en banc reversal of prior Third Circuit case law in the government official immunity area.  His government clients include the State of Delaware, New Castle County, Delaware, and other Delaware towns and cities.  He recently represented the State of Delaware in the United States Supreme Court in the original jurisdiction case New Jersey v. Delaware, where Delaware prevailed in its territorial claims to the Delaware River.

In addition to his litigation practice, C.J. frequently counsels directors and special committees on issues of Delaware corporate law, pre-suit litigation demands, and corporate governance issues as well.

C.J. is a member of the Delaware State, the Third Circuit, and the Supreme Court Bars as well as the Federal Circuit Bar Association.  He is a former Chair of the Delaware Board of Bar Examiners, and President of the Court of Chancery Historical Society.

In 2002 the United States District Court for the District of Delaware appointed C.J. Special Master for pre-trial proceedings in the largest securities class action filed in Delaware, In re DaimlerChrysler Securities Litigation.  Of the 20 opinions he authored, the parties sought review of only one, which was reviewed and affirmed by the District Court.  The Delaware District Court also recently selected C.J. along with three other attorneys to teach its annual trial practice course to newer attorneys.  

C.J. is often selected by parties to act as mediator or arbitrator in complex intellectual property and business disputes.  The District Court appointed C.J. Special Master to conduct pretrial proceedings in the following cases:

  • Forest Laboratories, Inc. v. Ivax Pharmaceticals, Inc. (C.A. No. 03-891 – JJF (Consolidated));
  • Teleglobe Communications Corporation v. BCE, Inc. (C.A. No. 04-CV-1266 SLR);
  • Hitachi, Ltd. v. Borgwarner, Inc. (C.A. No. 05-048-SLR);
  • Nokia Corporation v. InterDigital Communications (C.A. No. 05-16-JJF);
  • Lannett Company Inc. v. KV Pharmaceutical (C.A. No. 08-338-JJF);
  • In re:  DaimlerChrysler AG Securities Litigation (C.A. 00-993/00-984/01-004 JJF); and
