Summary Box: Google, Microsoft patent spat

THE PLAYERS: Microsoft vs. Google.

THE ISSUE: Last month, a consortium that includes Microsoft Corp., Apple Inc. and Research In Motion Ltd. prevailed over Google Inc. with a $4.5 billion cash bid for patents owned by the bankrupt Nortel Networks.

WAR OF THE WORDS: Google accuses the other tech companies of launching a “hostile organized campaign” against its Android operating system. It comes in a blog post from Google’s chief legal officer. Microsoft response in a series of tweets. That prompts a blog update from Google.
