What is LES International?

The Licensing Executives Society International (LESI) is an association of 33 national and regional Member Societies comprised of men and women who have an interest in the transfer of technology, or licensing of intellectual property rights – from technical know how and patented inventions to software, copyright and trademarks.

It is strictly non-political and is free to grow by the creation of member societies throughout the world irrespective of politics or the state of technology development. LES International has a constitution and by-laws.


First and foremost, LESI consists of the members of its national and regional Member Societies. The Member Societies, in turn, are the “shareholders” of LESI. LESI is governed by a Board of Directors who exercise its executive functions. The Board of Directors is elected by the International Board of Delegates who are themselves appointed by the Member Societies. Finally, LESI has various Management Committees as well as Industry, Professional and regional Committees.

The LESI Membership

All members of LES Member Societies are automatically members of LESI, with all the benefits that come with that membership.

Traditionally business-oriented, LESI counts among its 11,500+ members management representatives from companies located all over the globe, ranging from large multinationals to small start-ups.


However, LESI is more than that; boasting a membership diverse enough to also include scientists, engineers, academicians, governmental officials, lawyers, patent and trademark attorneys and consultants, LES is a broad community providing its members with access to a unique and varied global business network.
