Now, LES is offering a pilot global membership program to IP Owner organizations* to provide the benefits of LES membership to their employees around the world for one annual fee.

The journal is published quarterly and is designed to further the knowledge of the societies members and others in improving their skills, techniques and knowledge in licensing and protecting Intellectual Property.

Each issue of the Global News includes society news, details of upcoming events, information on committee activities, and calls to action.
