Being an active LESI member has significantly advanced my professional development, keeping me abreast of cutting-edge IP licensing issues and fostering valuable connections with professionals from various jurisdictions. The Annual Conference, held in interesting locations, is a yearly highlight for reconnecting with friends and colleagues.

LESI represents an international group of highly engaged individuals sharing expert knowledge and experience. I feel it has a positive impact on all IP professionals and licensing specialists who are members

LESI fosters professional excellence, where meaningful work discussions and collaborative brainstorming sessions lead to the creation of lasting worldwide friendships.

LESI is the gold-standard for meeting and networking with highly engaged IP professionals from all around the world, and for the quality of its content about the business aspects of IP assets. Its Young Members Congress (YMC) is a vibrant community of younger professionals and the best entry point to a global network of experts, while maintaining a casual approach to networking. LESI and its YMC committee have propelled my career to new heights!

As members, we look forward to meetings throughout the year to not only exchange and build on knowledge, experience, and emerging trends in the IP world, but to grow and connect as a close knit group of international friends and lifelong support.
