The GNU Project has some nice proze on this topic (last updated 2005/10/31).
Why no GIFs: "There are no GIFs on the GNU web site because of the patents
(Unisys and IBM) covering the LZW compression algorithm which is used in

When will creating 'real' GIFs probably be safe: "Of the places whose patent
databases we were able to search, the latest expiration date seems to be
Friday 11 August 2006. Until then, anyone who releases a free program for
