UK-based telecoms group BT is suing Google in the US over claims that six of its patents have been infringed.The British company's complaints centre on technologies at the core of Google's Android mobile system, search site, and a wide range of other services.
BT is seeking unspecified damages and an injunction against Google's continued use of its innovations.
The move marks the latest patent attack on Android following legal action by Apple, Microsoft, Oracle and others.
BT said it currently had a portfolio of around 5,600 patents and patent applications.
Its complaint states that it has invested heavily in mobile technologies and related services over the past two decades.
It then claims that its resulting patents have been infringed by Google's search engines, Android system, Google+ social network, eBooks, Maps, Offers, Docs, Places, Gmail, Doubleclick advertising management system, AdWords advertisement listing program and other services.
