Did you know that the pillar of corporate scum that is BT claims to have invented hyperlinking? Nor did I, but Prodigy do. They were unlucky enough to be the first ISP attacked by BT in the courts for abusing the US patent it submitted in 1979. A decision on whether the case will go to court is expected soon.
If successful in court, BT will follow it by squeezing cash out of other ISPs and, in theory at least, this could be extended to individuals.
So not happy with throttling broadband developments here in the UK, it seems BT wish to pull apart the US Web at its seams. Intellectual property assertion or not, this is frankly dispicable.
