BT Group plc (NYSE: BT; London: BTA) filed a whopper of a patent suit against Google (Nasdaq: GOOG) on Thursday, according to news reports published late Sunday night.

The complaint, posted on Scribd, says six of BT's U.S. patents are being violated by a lot of big-name Google products, including Google Search.

Other products named include Android Market, the Android operating system itself, Google Maps, Google Books and Google+.

That's right -- somebody cares enough about Google+ to file a lawsuit about it.

BT filed the suit in the U.S. District Court in Delaware. The company is asking for the usual, including injunctions against the continuation of the alleged infringements and damages.

Here's a summary of the lawsuit: Table 1: It's Mostly About Maps
