My company owns a lot of patents. Over the years we've contributed code to projects under &ldquo;GPL version 2 or any later version&rdquo;, and the project itself has been distributed under the same terms. If a user decides to take the project's code (incorporating my contributions) under GPLv3, does that mean I've automatically granted GPLv3's explicit patent license to that user?
