Justin J. Lesko is a registered patent attorney and a member of the Illinois State Bar. He is admitted to practice before the U.S. District Court for the Northern District of Illinois and the United States Court of Appeals for the Federal Circuit.
Mr. Lesko understands the intersection of licensing, litigation, and patent prosecution in patent enforcement matters and can navigate clients through those processes to efficient and lucrative resolutions, often on a contingent fee basis. He has extensive experience with monetizing and enforcing patent portfolios, including negotiating license agreements, assisting with complex litigation, leading continued patent prosecution, and defending post-grant challenges at the United States Patent and Trademark Office. His ability to advocate the merits to prospective licensees and ultimately negotiate license agreements to resolve disputes has led to millions of dollars in licensing revenue for his clients.
Mr. Lesko’s patent prosecution practice focuses on drafting patent applications and claims with an eye towards future enforceability, maximizing potential value for his clients. He has served as lead counsel before the Patent Trial and Appeal Board for appeals and inter partes review trials.
Mr. Lesko obtained his BS in Mechanical Engineering from Purdue University in 2006. Following graduation, he worked for two years at engineering and construction company CB&I, first on the design of pipeline systems for the Process Systems Engineering group, and then as a Field Engineer for a Liquefied Natural Gas receiving terminal construction project.
Mr. Lesko graduated from the DePaul University College of Law in 2011 magna cum laude, Order of the Coif, and earned a certificate in intellectual property law. He received the 2011 Allen J. Hoover Memorial Award, given annually to a third-year DePaul law student who is expected to make the greatest contribution to the practice of intellectual property law as determined by the school. He also served as a Member of the DePaul Law Review and participated in the 2011 Giles Sutherland Rich Memorial Patent Moot Court Competition.
