British Telecom has sued Google stating that the company’s Android and some other services have violated 6 patents of the Telecom giant.

These services include Google music, Androids, Google maps, Google+ (Google’s social network) and even Google search. With this BT becomes the fifth major company suing Google after Apple, eBay, Microsoft and Oracle over infringement allegations.

The suit was filed in a U.S district court in Delaware and states that a large number of the services by Google violate the patents of British Telecom. It seeks unspecified damages apart from injunction on Google’s part.

It is said that the patents infringed include a Navigation Information System and communications node for providing network based information service. In fact BT has claimed that the whole foundation of the Android market has infringed its patents.

It is to be noted here that British Telecom, one of the oldest telecom companies has over 10,000 to its name. The court papers suggest that earlier BT has sought a license from Google, though Google has refused for the same.

Florian Mueller, author of FOSS patents has said that if BT is successful than Google might have to change the way it delivers the OS to the various device manufacturers.

He also said that since Google is facing so many problems from the patent holders, it may force the company to change the licensing model of the Android and pass some royalties to the device makers.

A representative from Google has denied the allegations and has said that the claims are without any merit and that they are ready to defend themselves vigorously. A British Telecom spokesperson was unavailable to comment on the complete scenario.
