Welcome to the tablet game, Amazon. Just two weeks after taking the wraps off its Kindle Fire tablet, Amazon has already been hit with a lawsuit from patent licensing firm Acacia Research — a company that makes money by buying up other companies’ intellectual property and then licenses it out through a variety of subsidiaries. In other words, Acacia is a patent troll. The firm alleges that Amazon’s Kindle Fire infringes on several of its patents, including one that covers graphics on a touchscreen that respond when a user “writes” on said screen, and a second titled “System And Method For Displaying And Manipulating Multiple Calendars On A Personal Digital Assistant.” Acacia currently has multiple pending patent suits against Apple and other defendants that refused to settle with the firm.
