There are 400+ patents that cover G729, Many of which haven't expired yet.
Review the EULA on our G729 installer and you'll see the list of patents
and what country they apply to.

And as Anthony pointed out, there very well could be some that aren't
claimed yet, Our product Skew was G729AB, Even tho we were only shipping A,
we had someone come after us demanding money because of that, even tho we
were not shipping any G729B.

We use the sales to help support the project, so show your support, buy a
few licenses and wish Anthony a Happy Birthday its coming on the 7th  (
