Leon Radomsky focuses on strategic IP counseling and IP strategy, IP due diligence, agreements and opinions, and all phases of U.S. and international patent portfolio development, including patent application drafting and patent prosecution in the areas of nanotechnology, clean technology (such as solar cells, fuel cells and energy storage devices), semiconductor devices and processing, and materials science.   Mr. Radomsky represents a number of high profile early and middle stage VC funded nanotech and cleantech companies and leading VC funds in the nanotech and cleantech space.

Prior to joining The Marbury Law Group, Mr. Radomsky was a partner at Foley & Lardner LLP, one of the largest law firms in the country.  While at Foley, Mr. Radomsky was the founding member and chair of Foley’s Nanotechnology Industry Team and a founding member of Foley’s Green Energy Technologies IP group.  He drafted and prosecuted a large number of key patents in the nanotech, cleantech, semiconductor and materials science areas, developed and implemented an IP strategy for a number of start-up companies, and counseled a number of VC funds and target companies in a course of IP due diligence during VC investment.

Prior to joining Foley, Mr. Radomsky worked as a patent examiner in the U.S. Patent and Trademark Office, where he examined patent applications in semiconductor device processing and developed a broad knowledge of semiconductor device processing, solar cell, light emitting diode and liquid crystal display fabrication technologies.  Prior to that, he was a doctoral research assistant and teaching assistant at Columbia University, where he gained expertise in wide band gap semiconductor physics and testing, metallurgy and opto-electronic materials processing.

Mr. Radomsky was recognized in the Legal 500 US 2009 Edition and in the Legal 500 US: Volume II: Intellectual Property, Media, Technology, and Telecom 2007 Guide as a top attorney for patent prosecution. He has also been named one of the Top Ten Intellectual Property Lawyers Influencing Nanotechnology by Nanotechnology Law & Business.

Mr. Radomsky has authored numerous legal articles and book chapters. He authored a chapter on IP due diligence in "Structuring Patent Licensing Transactions" published by Aspatore Books and was featured in ReedLogic Video Leadership Seminars on IP due diligence and on providing superior client service to generate referrals to new clients.  In addition, Mr. Radomsky has also authored articles which have appeared in numerous publications, including Intellectual Property Today, Patent Strategy & Management, IP Law 360, Berkeley Technology Law Journal, Nanotechnology Law & Business and R&D Journal. The articles have covered diverse legal topics, including claim interpretation, an analysis of world wide semiconductor chip layout protection laws, government rights in nanotechnology patents, a summary of the first Federal Circuit nanotechnology decision, and patent strategy, inventorship, ownership and legislative issues facing nanotechnology and other high tech start-up companies. While still in law school, Mr. Radomsky was awarded the Rossman Memorial Award as the author of an article in the Journal of the Patent and Trademark Office Society that made the greatest contribution to the fields of patents, trademarks and copyrights in 1997-98. Mr. Radomsky has also co-authored numerous articles on semiconductor testing and physics.

Mr. Radomsky is an active member of the American Intellectual Property Law Association (AIPLA), where he served as past chair of its Chemical Practice and Young Lawyer's Committees. Mr. Radomsky frequently serves as an instructor at the annual AIPLA Patent Prosecution Basic Training for New Lawyers seminars and prepared portions of the seminar textbook. Mr. Radomsky has also made numerous presentations at AIPLA committee meetings on subjects ranging from IP due diligence for venture capital investment in start-up companies to opinions of counsel to recent case law. Mr. Radomsky received the AIPLA project award as a co-author of the AIPLA International Patent Handbook.
