[..] : "Ecash" is a registered trademark of DigiCash. It is registered : with the Benelux trademark office and the United States : trademark office. I believe that it is considered unwise to use : minor variations on trademarked names, but I'm not an : intellectual property rights lawyer. The Benelux (Netherlands, Belgium and Luxembourg) trademark laws don't allow for slight variations, certainly not if there is a change that people get confused, it is very very likey that the judges of the benelux trademark court will decide that ecash and e-cash are just to simular, and will thus confuse the public. (art 5 lid 1 BMW) btw: I'm surprised DigiCash didn't file for a European Trademark, but opted for Benelux and US protection. bEST Regards, -- -AJ-
