Charles E. Miller, Ph D. is a patent, trademark, and copyright lawyer in the Intellectual Property Group of Leichtman Law PLLC where he is a Senior Counsel in the Firm’s midtown Manhattan offices. His practice focuses on counseling and representing clients in IP controversies and transactions involving intellectual property cases in manufacturing, process, and design industries and technologies including chemicals, polymers, pharmaceutical and life sciences, medical devices, and machinery. He guides and assists individuals and companies in managing and adding value to their IP assets, and represents their interests in technology-related trials and appeals in court litigation, contested proceedings in the U. S. Patent and Trademark Office, alternative means of dispute-resolution, and licensing in the private and government sectors.

Since prior to joining Leichtman Law, Dr. Miller has been in private practice beginning at the law firm of Pennie & Edmonds where he worked on patent and trademark cases from 1971 during which time he served on that firm’s executive, membership, lawyer compensation, recruitment, and practice development committees. Before that, from 1966 to 1971, he trained in the law departments of Allied Chemical Corporation (now Honeywell International, Inc.) and Celanese Corporation, where he was involved in patenting the companies’ inventions.

As a practitioner, Dr. Miller also has been an arbitrator in commercial cases for the American Arbitration Association and for the World Intellectual Property Organization. He testified in patent and related antitrust cases as an expert on patent litigation and on U. S. Patent and Trademark Office customs, practices, and procedures, and served as special master in patent infringement litigation on appointment by the U. S. District Court in Massachusetts. Dr. Miller taught patent law and appellate advocacy as an adjunct professor at St. John’s University School of Law. He is a founding member of the Association of Amicus Counsel and has participated as counsel-of-record in amicus curiae briefs filed in high-profile IP cases in the U.S. Supreme Court and in the U.S. Court of Appeals.
