The alleged dispute has continued for almost five years but it came into light soon after Skype revealed details of the same in its 250 page S-1 document.

A representative for BSkyB stated: "Sky is involved in a long-running dispute with Skype in relation to several trade mark applications filed by Skype, including, but not limited to, television-related goods and services."
