Ray Ozzie says -
Some months back I became aware of the patent US 5,838,906 and the Eolas lawsuit against Microsoft, and followed a bit of conversation on the Net related to it. As many, I believed the the issue would quickly go away because of ample prior art. Regrettably, this seems not to be the case.
It now seems that perhaps the browser itself and the browsing experience may have to be nontrivially modified as a result of the judgment. Although a bit late, if some of us perhaps dust off our old code, is there a chance that we could still save the browser through demonstration of clear prior art?
For my own interest, and for the record, I recently spent a little time pursuing my intuition that Lotus Notes R3 might be viable prior art relative to the patent in question. I am not an attorney, and I am surely not well versed in the nuances of the case, but it seems to me after initial investigation that there is indeed quite a bit of relevance.
