Nokia goes after RIM with 3 additional patents

It seems Lady Luck has something against Research in Motion. As if it didn’t have enough problems to deal with, the Canada-based Blackberry maker has been sued by Nokia. Again. Following its patent-suing spree in May, the Finnish phone manufacturer is now suing Research in Motion with three additional patents. Nokia has filed the patent lawsuits in Munich. This is in addition to the earlier lawsuits filed by Nokia against RIM in Dusseldorf (2), Mannheim (2) and Munich (3). So far, the Finland-based cell phone manufacturer has sued RIM only in Germany, while it has sued HTC and ViewSonic over some patents in the US as well.Click here for full story
