Daniel "Dan" Ravicher serves as Executive Director of the Public Patent Foundation... (wikipedia)
I think it's stupid that this type of policy is legal and profitable.
The patent office's decision has no preclusive effect on a court, and there are indeed cases where the patent office made a decision in a re-examination supporting a patent and a court later looked at the same exact issue, disagreed with the PTO, and found the patent invalid.
This reexamination is concluded, but that doesn't mean this patent can't ever be challenged again.
They want a one-sided debate where we weren't allowed to participate. Microsoft gets an unlimited number of arguments, and we're barred from participating, so it's a pretty unfair process.
