GPL version 3 is arriving 16 years after version 2 of the license for open-source software. Questions remain, however, about who exactly will adopt it. Among improvements is a copyright technology not found anywhere in the world with the goal of providing uniformity in different jurisdictions, said Brett Smith, licensing compliance engineer for the foundation. An explicit patent provision in GPL 3 means people who contribute to free software cannot sue users for patent infringement, Smith said. This was not clear in the GPL previously. The foundation in version 3 provides what has been described as "patent-insurance" in response to the Microsoft-Novell arrangement. Will you buy this patent insurance?"
