And just like that, another one of the tech industry's epic patent battles is coming to a close. Google and Microsoft have dropped all 20 (!) of the lawsuits they've filed against each other, ending their five-year dispute over everything ranging from phones (Microsoft's main gripe) to Xbox video playback (Google's gripe, and formerly Motorola's). The two will now partner both on technology as a whole and on "certain patent matters," such as building a royalty-free video format that prevents these kinds of legal fights in the first place. The truce is no doubt a relief if you're tired of seeing endless stores about the lawsuits (guilty!), although it's not a complete shock if you've been following changes in corporate culture.
