About Us


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.

Unlike so many firms, we encourage our clients to directly access and review their intellectual property portfolios through our secure, online extranet. This can be done as easily as accessing an online bank account using our fully-integrated technologies. We empower clients not only to review their records, but proactively select and obtain reports, on-demand, concerning all of their intellectual properties, whether they comprise patents, trademarks, copyrights or a combination of such holdings. Our clients are able to do this at any time of day whether it is to prepare for a Board of Directors meeting or to monitor the progress of an important matter. There are no charges for this service. Our clients select Leason Ellis LLP because we recognize that their needs come first, and that is the hallmark of excellent service in any sector.

We pride ourselves in delivering value to our clients by providing intelligent and unexpected solutions to the legal challenges that they face. Our clients benefit from the years of experience cultivated by our professionals at established specialty intellectual property firms.

There certainly are firms much larger than ours, with clients of all sizes, but with us, you will receive the personal attention of all of the attorneys and professionals on your team and have access to and control over your information at all times.

We invite you to contact us and learn more about our experience and personalized approach to intellectual property law and management.
