> No it isn't. You either infringe a patent or you don't. It is better not to know about the patent if you get caught infringing because of the treble damage possibility that nknighthb referenced, but "I didn't know about that patent" is a meaningless defense, you're still on the hook for the base cost of the infringement, just not 3x whatever that base is. So yes it is, then?
