Most people buy the codecs as software packages from one of a few 
companies that specialise in writing major DSP modules. The royalty 
those companies charge for the software usually includes the patent 
fees, which they pass on to the patent holders. If you are lucky, they 
will indemnify the equipment maker that they have paid all relevant 
charges. :-)
