In general I am a little bit confused from patents.

Ok JBIG uses some patents. Up to know I have thought, that JPEG uses patents ( arithmetic coding? ) too. Never heard, that someone pay license fees for JPEG.

But on www.jpeg.org/public/jpegnew.htm there is a line which says that IBM will frees it QM patent. What should I think?

Some time I have read, that a license from one patent owner is enough to use JBIG.
