Open licenses are private arrangements that work within the current legal regime to encourage innovation, discourage trolls, and help attract top engineering talent. It is a win-win solution for different patenting companies and user’s society. There are several different types of most common open licenses. A License of Transfer Agreement (or shortly, a LOT agreement), that helps to prevent legal suits from non-practicing entities that purchase patents for the sole purpose of enforcing them (called Patent Assertion Entities, or PAEs). Under the LOT Agreement, every company that participates, grants a license to the other participants where the license becomes effective only when patents are transferred to non-participants.
