Rovi is continuing its court case against Ziggo, according to the IPO prospectus of the Dutch cable operator.

Rovi has issued a robust response following Thursday’s High Court decision that ruled three of its Gemstar EPG patents to be invalid.
Virgin Media has succeeded in the patent dispute brought against it by Gemstar TV Guide. The London High Court rulings call into question the ability for intellectual property rights holder Rovi to enforce its patents both in the UK and with operators around the world.
