I imagine it becomes a problem to track down all of these IP's when you have so many countries with so many trademarks and how ambiguous these suits have been. If they get a great Idea for something and they find that some guy in france made something called a "netbook" that was to made to catch books in 77' that you were just going to have to be sued. I think a simple solution would be to just add some numbers to the end of any proposed marketing scheme. For example, instead of wasting all of this money on long gone companies wanting free money for using the term "netbook" just slap an arbitrary number at the end. "Netbook2122" BOOM! we just improved the bottom line.
