Sorry, wrong wording from me. Licensing and patents are not quite the same
(e.g.: Opus has a FOSS license but is covered by some patents*) so I
should've used "licensing" instead of "patents" in my previous reply...
* "Patents" section on the License page of Opus' website
<http://opus-codec.org/license/>
