Rovi Solutions Corporation v. Virgin Media Limited, Patents Court (Chancery Division), High Court of Justice, London, UK, 15 May 20014, Case No.  EWHC 1559 (Pat)
Mr Justice Mann of the Patents Court found for the defendant, Virgin Media, against Rovi in an action for infringement under EP (UK) 0 862 833.
Rovi contended that Virgin Media infringed its patent relating to set top boxes (STBs) which generate a prompt on the screen inviting input from the viewer, and if that input is made then a further message is conveyed, or something else happens in the STB by way of the execution of computer code. The core of the alleged invention related to the existence of two signals which achieved the required result. The first signal, referred to as the “identification signal” was responsible for bringing about the display of an indication symbol or prompt on the screen. The second signal (the “information signal”) was responsible for displaying a message which was intended to appear if the user responded to the prompt (by pressing the relevant button on the remote control of the TV or STB), or for running computer code contained in the information signal or triggering a program already resident in the STB.
