Michael V. Messinger



Mr. Messinger is a director in the Electronics Group and the leader of the firm's Alternative Energy and Climate Change practice area. He handles complex patent matters involving inter partes and post-grant review, reexamination, reissue and appeals. He works with company managers, directors and employees to identify and leverage intellectual property assets. He is a leader in the area of fast-track patent examination in the United States and abroad.

Mr. Messinger has extensive experience prosecuting U.S. and international patent applications and developing strategic patent portfolios. He has written and prosecuted numerous patent applications including those related to computer networking (Internet, World-Wide Web, Java technologies), communications protocols, browsers, geographical information systems, high-speed optical communications, optoelectronics, graphics processing, data mining, voice-over-IP, cryptography, and multi-processor computer architecture.  Hundreds of patents he helped obtain have been successfully enforced or acquired.

Mr. Messinger has also provided infringement and validity analysis in opinion work and in support of litigation for computer-related patents, including having served as a patent expert in an EDVA litigation.

Prior to joining Sterne Kessler, Mr. Messinger worked as a patent agent.  He was a patent examiner for over six years in Group 2500 (Radiant Energy) at the United States Patent and Trademark Office. He examined patent applications and granted U.S. patents covering a variety of optical electronic circuits and systems including video camera inspection systems, scanners, fiber optic sensors, imaging CCD arrays, and photosensitive semiconductor junctions.  Mr. Messinger regularly publishes and speaks on emerging topics in patent strategy and practice in the United States and abroad.

Mr. Messinger taught for several years at the Patent and Trademark Office University and Northern Virginia Community College in the areas of patent law, intellectual property law, and business organization.  He is an adjunct professor of Patent Licensing at Georgetown Law.  He also teaches Patent Office Litigation at George Mason School of Law - the first course of its kind in the nation. He serves as the Virginia area coordinator for the Cyprus Friendship Program.

Additionally, Mr. Messinger is a contributing author of Patent Office Litigation, Second Edition, published in 2017, and the two-volume set Patent Office Litigation, published in 2012 by Thomson Reuters Westlaw. The first edition focuses on the new contested proceedings under the America Invents Act, while the second edition provides a fresh and comprehensive exploration of these proceedings. Both books examine how the proceedings interact with other aspects of patent procurement and enforcement, and deliver practical analysis and advice.
