Here's a quote of a quote from a [ZdNet article | http://zdnet.com.com/2100-1104_2-5291403.html?tag=zdfd.newsfeed ] that gives me relief:

;:"If you have knowledge and are found to infringe, a court can punish you," tripling financial penalties, Ravicher said. "If you say you didn't know and didn't see it, a court can't punish you. It's a screwed-up rule."

So I guess you would still be forced into paying to use any patents that you're found to infringe on but only after the court finds you guilty.
