How does Grandstream become patent indemnified for their hardware? I
would assume they did not pay for a license for G723,1 and G729 directly
to the patent holding company. Maybe they did. I always assumed the
indemnification came with a DSP that implemented the codec.
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. :-)
