So let's see what the MPEG colleagues will have to say.

Nor does any other SDO.

Typically SDOs will issue a call to their members to declare whether anyone holds essential IPR for a specification. This will make the patent holders known to each other and to the other SDO members (transparency). In the case of DVB for instance, DVB's terms then oblige the IPR holders to sit together and create a single patent pool for the spec in question (one-stop-shop). Typically this results in the IPR holders delegating to Via Licensing or MPEG-LA as you said. Don't know about MPEG's terms though.

Should we delegate this decision to the IPR holders (if any) maybe. ;-) Just my two cents...
