Charles: FYI the patent office got their hands slapped real hard over patents...
There has been a changeover in patent law, and not just about algorithms.
I was noticing more and more patents on things already in the public domain - mainly those things so well known, one didn't see patents on them. Then the profiteers showed up and tried to lock them up. Now there are at least some procedures in place to dispute these over-broad patents.
