I did a brief googleing of "jbig patent", and the best reference on jbig2 I found was:

http://www.jpeg.org/jbig/faq.phtml?action=show_answer&question_id=q3f042a7298c94

Apparently there are only two known patentholders relevant to jbig2, IBM and Mitsubishi, both of which are offering free licensing. I will be testing this, but if anyone has more reliable info, I'm curious.

We were able to obtain licenses for JBIG2 from various patent holders. It took about 6 months.....
