David Leason – Managing Partner – leason@leasonellis.com
Leason Ellis is one of the largest IP firms in New York outside of Manhattan and rated among the top firms in the state for our patent, trademark, and copyright services. Our broad array of clients range from Fortune 100 companies, to midsize and small companies, to start-ups, inventors and entrepreneurs.
We protect the IP rights of domestic clients in the U.S. and abroad and, in turn, we directly represent many global companies in protecting their rights in the U.S. We also work on behalf of foreign law firms to develop and enforce their clients’ intellectual property rights here.
Our unique approach to building a business has allowed us to be more sensitive to our clients’ needs as well as responsive to their communications. Our strategic size encourages collegiality among attorneys and staff and works to the benefit of our clients, who gain the most from the teamwork we foster.
