While Samsung and Apple are in the midst of their fierce patent battles all around the world, in the parallel world BT has fired legal claims over six patents Google's way.

The telecoms and broadband provider stated that Google was infringing its communications networks patents mentioning specifically Google's Map services, the Android Market, books as well as its music service.

A patents blogger, Florian Mueller, was contemplating whether or not this dispute would be taken further to Europe. He wrote:

"I don't know yet whether BT also brought litigation in Europe over local equivalents of those patents.

"It would certainly make sense to take advantage of the swift and rather patent holder-friendly decisions taken by certain German courts in order to get Google to pay sooner rather than later."

While BT stated that it was keen on protecting assets which it heavily invested in and considered its own intellectual property, Google has been reported as saying to CNet:

"We believe these claims are without merit, and we will defend vigorously against them."

BT would like Google to pay royalties, all legal costs and three times the sum of damages.
