BT is taking legal action in the US against games company Valve for allegedly infringing on four of the UK telecoms giant’s patents.

A BT spokesperson told Ars: “BT can confirm that it has commenced legal proceedings against Valve Corporation by filing a claim with the US District Court of Delaware for patent infringement. The patents in question relate to online computer or video gaming platforms, digital distribution services, and personalised access to online services and content.”

Ars has contacted Valve for its comment on BT’s move, but has not yet received a response.
