I think that the delineation of patent owners and NPEs (which, come on, is just a nice way of saying ‘patent troll’) is very important. It helps to define the lawsuits. Yes, the owned patent may be valid. Yes, the owner of said patent has every right to protect it, should it be valid. But the use (practical or licensed) of the patent is important to know in many of these cases. I’ll go a step further. The age of the patent is as–if not more–important.
