I thought Blackberry/RIM actually WON one of those, but then ended up paying $300M anyway? The press reporting was unclear, but that's what it seemed like had happened, which never made any sense to me. Maybe it was still pending an appeal by the patent holder?
Again, I don't know enough of the specifics. I'll ping him and see if they did that.
