Robert Isackson, is an accomplished, front-line IP litigator who approaches client service by working with the client to identify the problem in the business context. Then, using his diverse experience to bring a fresh perspective, he identifies key issues and develops creative and cost-effective strategies that align with the client’s business objectives to move its business forward. Providing front end clarity to reduce and manage client risk, Rob has nine patent and two arbitration trials under his belt and led litigation teams in over sixty patent and other IP cases filed in more than twenty states. Rob also translates his broad litigation experience to help clients with IP due diligence, freedom-to-operate opinions, procurement, and transactions. He has obtained more than two hundred U.S. patents and advised on dozens of IP deals and various technologies. In its 2021 rankings, IAM Patent 1000 said this: “Isackson applies a practical, common-sense approach and has the ability to explain complex matters simply, yet precisely. Unlike many lawyers, he doesn’t equivocate, but provides direct and useful advice. He is insightful about how intellectual property can be employed to drive value for a company.”

Beyond client work, Rob is President of the New York Intellectual Property Law Association, a Board Member since 2015, and active on its Amicus and Legislation committees. Since 2012 he has served on the Intellectual Property Owners Association Amicus and Trade Secret Committees. Rob has helped author over a dozen amicus briefs and regularly speaks on IP issues, from ethics to biosimilars, at association meetings. Rob holds J.D. and B.S.E.E. degrees from the University of Michigan. Before law school, Rob fried circuits in an electronics design lab, worked in an auto factory, and washed dishes at a Utah ski resort, which encouraged him to meld his passion for technology with advocacy to become an IP lawyer.

Being an excellent intellectual property law firm is not about size and it is not about history. It is about having skilled and accessible professionals providing service in a timely and effective manner. We established Leason Ellis LLP to provide clients of all sizes with personal attention and strategic insight, in a service-oriented setting. Our goal is to be the firm of choice for clients who demand quality legal advice, attentive, personal service, and superior intellectual property management tools.

To achieve our goal, our professionals handle a broad variety of technologies and a diverse, yet interrelated spectrum of intellectual property issues including IP portfolio development, patent prosecution, licensing, trademark clearance, freedom to operate, and strategic assessments of competitors’ infringements. We apply our interdisciplinary experience and creativity to each of our projects, whether it is for the benefit of corporate clients trying to operate in competitive industries or for independent inventors who want to extract all that can be had from their ideas. Our attorneys are mindful of our clients’ business objectives and we leverage that understanding to develop comprehensive plans that address the short- and long-term needs of our clients.
