Interesting links about patents and GPL:

Raph Levien has several patents and a license for GPL programs. See http://www.levien.com/patents.html. Raph's license might even more liberal than it looks: I still wonder whether a proprietary linux application (such as Oracle) can be said to be "practiced in conjunction" with software distributed under the GPL (such as the kernel or glibc).

The DjVuLibre project comes with a recently updated patent license. See http://djvu.sourceforge.net/licensing.html. It is slightly more restrictive than Raph's licence, but still free enough to have DjVuLibre listed in the FSF free sofware directory.

The DjVuLibre license was obtained because we (the djvulibre developers) maintained a constructive discussion with the Lizardtech lawyers. Without such a discussion, a corporate lawyer is tempted to produce a non-license and to convince himself that this will be good enough for the free software community. What do they know, after all?
