This seems a worthy point to raise in a liaison to ISO SC29/WG11 and and 
perhaps to proposers of the MPEG tracks.

There's also a resolution that MPEG members make WG 11 aware of market 
developments in the space.


 From Resolutions, the 98th SC 29/WG 11 Meeting, 2011-11-28/12-02, 
Geneva, Switzerland  [SC 29/WG 11 N 12254 

3.11 Part 29 Web Video Coding

3.11.1 The Requirements and Video subgroups thank Apple, Cisco, 
Fraunhofer HHI, Magnum Semiconductor, Polycom, and RIM for their 
response to the CfP on Internet Video Coding.

3.11.2  The Requirements subgroup recommends that proponents of 
technology for Web Video Coding further improve the support for their 
proposal in order to meet market needs as identified in the IVC CfP.

15.3.3 The Requirements subgroup recommends that MPEG members make WG 11 
aware of market developments in the space addressed by IVC.

> I sort of agree with the sentiment of this but the problem is that it is often not practically possible to figure out if any given codec is royalty free or not and the IETF explicitly does not take on the task of trying to figure out if a given technology actually infringes on a given patent or not. I don't think a requirement like that would really fit inside the IETF process.
