A large percentage of the patents applicable to G.729 are held by France 
Telecom. Now guess whether they bothered to get those patents in France. :-)

There are some software patents in the US for algorithms to speed up the 
computation of G.729 on a processor. I doubt those could have got 
through the European patent systems. The basic signal processing patents 
certainly have.
