Having broken up with one celebrity, BlackBerry is now suing another. The Canadian Press reports that the Waterloo-based smartphone maker has filed a lawsuit against Typo Products, a company co-founded by all-purpose personality delivery system Ryan Seacrest. Typo’s product is a snap-on keyboard for Apple iPhones, designed to mimic the very same QWERTY keyboard that, by some analyses, ruined BlackBerry’s future. (It’s available for preorder.) BlackBerry’s allegation is that the mimicry is so close that it constitutes intellectual property theft. Sorry, Seacrest.
