Patent von British Telecom auf Hypertext-Verweise

Diese Patent wurde offenbar in Europa nicht beantragt. Zum Antragszeitpunkt standen die Chancen hierfür in Europa schlecht. Heutzutage steht Patenten dieser Art auch in Europa (wie in den USA) nur die Hürde der Neuheit entgegen: man muss nachweisen, dass es genau das gleiche schon vorher gab. Technizität und Erfindungshöhe sind praktisch keine Hindernisse, da Programme per se als technisch gelten und auch die trivialsten Gedankengänge, sofern sie etwas mit Rechnern zu tun haben, als erfinderische Schritte gewertet werden.
