BT to sue Valve over patent infringement
BT has filed a patent case against leading PC gaming platform company Valve
BT is set to sue Valve, the company that runs the Steam online gaming platform, for patent infringement.
The British telecoms and technology company claims that Valve has used four of its patents related to computer and video game platforms, digital distribution services and personalised access to online services and content. The action concerns chat, subscriptions, broadcasting and call control protocols.
BT says it has warned Valve on multiple occasions about the infringement but received no response.
The case was filed in Delaware in the US in July.
The complaint names Valve's Steam Library, Steam Chat, Steam Messaging and Steam Broadcasting services as infringing patents.
BT said the action was necessary to protect its investment in innovation and its large portfolio of patents, and to gain compensation from Valve for profiting from patented technology.
Some commentators have pointed out that the processes and ideas described in the patents are very general, and could easily be applied to other online services such as YouTube, although there is no indicator of the possible success of any legal action or whether BT intends to sue any other companies.
