Its always been expected that the entire Net, including Yahoo Groups, would be autonomously data-mined for early AWE content, as industrial or academic interest, or AWE IP legal battles, dictate. Old Forum mirrors exist on Wayback, in Joe’s public archives, and various member email accounts. Its not lost.
A legally enforceable financial monopoly is the primary reason patents exist. Ventures do raise funds from junk patents, and governments skim filing fee revenue, but this was not the original idea. Patent filing is not an ideal format for knowledge sharing, like open academic publishing.
If only patent filers could or would do more public knowledge sharing. They tend to be the least sharing by nature. Of course they are welcome on Forums, for whatever they can add.
Regarding Makani’s patented architecture as blocking IP, or as useful art. The claim for no blocking IP is general. Anyone can still make AWE despite any patent. Makani has patented one of the most marginal schemes imaginable, with many prior-art roots. If only the power-curves were public, it would be clearer that it has already scaled past its sweet-spot, plus it crashes quite often. Then there are all the imitators. They are not paying royalties because the Google patents are junk, and would likely fail in Court challenges.
Finally, the Old Forum has been a repository of known Failure Modes that may have legal liability implications for any player that overlooked or ignored the warnings.
