here's a wee story of interest ( well I think so) I found while surfing the net.
Seems the judge found in this case it was for sale and allowable to resell it although there are aspects of the rights still unexamined. I guess this has implications for the whole CAD industry seeing as how they all perpetrate much the same, you might say, 'draconian' conditions. on their prized 'customers'.
there is a link to the judgement there (PDF format)
