The thirty plus year history of OSS has shown the power of collaborative development in key technologies/markets such as Enterprise, Mobility, Cloud, Computing, IoT and, more recently, Automotive. New and rich pathways to innovation have been nurtured through "all in collaboration and contribution". Following the Technology Community's lead in each of these areas, legal communities of interests have formed to enable freedom of action and safeguard this critical element of collaboration that yields new novelty and market alteration. These communities of interest include now mature legal solutions such as OIN and, more recently, Open Chain. This talk will discuss these solutions and how they arose out of the collaborative model that sits at the core of all OSS projects and how they are evolving every day to become part of the DNA of projects like Linux, Open Stack, Android, Chrome, and now AGL.
