Reject the mandate, do not implement VP8, and be formally therefore not conformant and therefore not in receipt of a license from company X; risk a ruinous lawsuit from X. > > 3. Do not implement WebRTC, and risk a ruinous loss of relevance. I don't see the risk of 1. having changed because of the IETF's statement. Plenty of small companies are already doing 1. and have had to risk getting sued by Nokia at this point in time already. In fact, it's a risk that small companies always have to deal with since there is so much patented technology around that you invariable will step on something. I doubt very much that the IETF's decision has any impact on small business' risk in that space at all. > I do not think that the IETF should be placing anyone into the position of having three extremely unpalatable choices. For a small company in the WebRTC space, 3. is a non-choice. 2. Is more of a business decision than an IP decision - which market are you trying to address? Are you trying to be interoperable with (current) browsers - then implement VP8. Are you trying to be interoperable with legacy devices - then implement H.264 (and probably even H.263). If you are trying to argue for a large company, the situation changes. However, as a large company, you tend to have an existing portfolio of patents. You're already playing the game of patents. As long as your hypothetical "IPR owners to grant a license only to ‘conforming implementations’" doesn't happen, you are free to choose 2. and avoid Nokia. As for the threat in your option 2. - I can only see Google with IPR around VP8. Now, Google's IPR statement on WebM codecs, which includes VP8 and VP9 currently states: "Google hereby grants to you a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license" http://www.webmproject.org/license/additional/ The word "perpetual" implies (to my non-lawyer eyes) that they can't suddenly change this to mean "only if you are conformant to the standard". So you can't be referring to such a risk associated with VP8 being created by Google. I don't know which other company you would want to be afraid of for your hypothetical threat in 2. Could you clarify?
