Also I would note the two statements (1297 and 1164) appear to be (only?) a single patent application for a method of estimating noise levels with 3 independent claims. As further progress is made, it might be helpful to understand scope and prior art, and relationship to an entire contribution, and the specific quantified value of the novelty identified in the international search opinion of applying opposite non-linear functions.
Though not reflected in the disclosure, the US application claims priority to a Great Britain Application No. 0703275.8, filed Feb. 20, 2007.

Perhaps someone familiar with this application would correct any mis-impressions above?

I am just noting some restrictions that seem especially onerous to me.In practice the first clause does not immunize Skype from lawsuits. Many companies have similar "defensive suspension" clauses, and they still get sued fairly regularly.There are different kinds of defensive suspension. For example, the W3C allows defensive suspension, but only for lawsuits on patent infringement: """ a W3C Royalty-Free license ... may be suspended with respect to any licensee when licensor is sued by licensee for infringement of claims essential to implement any W3C Recommendation ... [but] may not impose any further conditions or restrictions """ (http://www.w3.org/Consortium/Patent-Policy-20030520#sec-Requirements" rel="nofollow">http://www.w3.org/Consortium/Patent-Policy-20030520#sec-Requirements) That seems like a reasonable case for defensive suspension. Skype's wording, by contrast, is totally unreasonable, as it extends the defensive suspension to _all_ lawsuits, no matter their object. I expect most companies to use the IWAC, and maybe even most humans eventually. The retroactive revocation means that these people can be deterred from suing Skype/Ebay even after the patents have all expired. It's absurd, not to mention legally questionable.The second clause ensures that someone outside the IETF cannot take the Skype technology, improve it, and offer a competitive proprietrary codec that uses Skype IPR. If you modify the codec, you should be doing it in the context of the IETF standard.And once the standard is made? Skype could effectively block the IETF from creating an improved version of its own codec, or any optional extensions (they're not "necessary"). I don't think that's reasonable at all. --Ben
