By the way, I think you're confusing the Software Freedom Conservancy (an umbrella organization for projects, similar to Software in the Public Interest, the Free Software Foundation, and the Apache Software Foundation) with the Software Freedom Law Center (an organization that provides legal services to developers and projects).

In some court cases (e.g. those involving BusyBox and some GNU software), the Software Freedom Law Center led the litigation without having ownership of relevant copyrights. However, that was only possible because the owners of those rights filed the complaints and sought the SFLC's legal representation.
