Re: [codec] Proposed Guidelines update , was: Re:Opus codec licensing

[Erik Norvell <[e-mail]>]

Hi Jean-Marc,

Thanks for your reply.

The goal is to develop a codec that would be free and available to use for everyone. If the license is bundled with the software or aquired automatically I see no issue there. It is rather the agreements you may enter by accepting such a license. If the use of the codec may bring disadvantages and cost into patent litigations which may not be related to the use of the developed codec, I see this as a problem.

I am not addressing Skype's IPR statement directly because I think the guidelines should apply for all. Skype has, as everyone else, the right to submit their technology under whatever terms they decide. It is up to this group to decide if we accept them or not. Please note that I am not talking about binding rules of the WG, just stating a preference for unencumbered technology is this choice is given. 

The term "unencumbered" is a bit vague and people seem to have different definitions. When I read the Codec charter I think it maps to the "No license required" option. My insistence on this term is because it is a clarification of the term unencumbered using language already known in IETF. 

Best regards,
Erik

Hi Erik,

Sorry for not replying earlier. I originally wanted to wait for the Xiph IPR statement, which should still appear before the meeting. Instead of aguing indirectly over the terms through the guidelines document, why not address these issue directly? Your insistence 'No license required' seems to indicate that you are unhappy with the current terms proposed. Is that the case? If so, maybe we can discuss the actual problems you find with current Skype terms, as well as the terms that will be submitted by Xiph and (I assume) Broadcom.

In general, I totally agree that having to explicitly request a license would be problematic. On the other hand, I tend to like the idea of an "automatic license" that everyone gets, but that can be revoked if someone starts suing people for implementing the standard. In fact, I believe that such clauses can actually make the codec safer to use and redistribute.
