I would never had thought of finding a such good example of stupid use of software patents. I do not like so much Microsoft, but it’s somewhat ridiculous that a company called E-Data can launch a litigation on the claim they own in Europe a supposedly-valid patent on:
the transmission of information to a remote point-of-sale location, where information is then transferred to a material object
This description apparently fit the sale of a song at the Microsoft music store that can be burned later to a CD. But what does it do not covers? You can think what you want, but it has not much sense to me.
