<br>Sorry for jumping ahead, but this something I really don't understand.<br>Let's assume that there are currently a few valid US patents on JPEG,<br>MJPEG (There are probably more) as well as for MPEG4.2 (xvid divx wmv1
<br>and many more are MPEG4 part 2 implementations). My question is, so<br>what? A patent is a territorial legal being -- it is valid only where it<br>was granted. Even if JPEG is covered by hundreds of active US patents,
<br>and some unenforceable EU patents, it has nothing to do with countries<br>in which the OLPCs will be distributed, since those patents are invalid<br>there.<br><br><a href="mailto:salsaman@xs4all.nl">salsaman@xs4all.nl
