IANAL. My understanding is that patents do neither forbid _usage_ of patentented technology, nor manufacturing a product using a patented innovation for ones _own_ use. However, they forbid exploitation of the patented technology by e.g. selling products with patented innovations without a license. If my interpretation is correct, there is no problem in producing a sc for ones own use, but of course if someone other than the original author of the the vdr-sc plugin is using it, the author of that plugin is violating the patent. Whether the user of the plugin is breaking any law in this case is unclear to me. Also, if the service provider has some conditions on which devices to use the leased smartcard you might be breaking them. yours, Jouni
