After Motorola accused Apple of patent infringement in a recent lawsuit, Apple went ahead and filed two lawsuits of its own against Motorola in US federal court. The suit claims that Motorola has copied some of Apple’s fundamental intellectual property in regard to the multi-touch interface on the Droid and other phones. According to the lawsuit, which was filed on October 29 in the US District Court for the Western District of Wisconsin, Apple alleges in two separate actions, that Motorola has infringed six of its patents in their Droid, Droid 2, Droid X, Cliq, Cliq XT, BackFlip, Devour A555, Devour i1, and Charm 1 phones. The first case involves multi-touch technology, including patents on “Ellipse Fitting for Multi-Touch Surfaces, Multipoint Touchscreen” and “Object-Oriented System Locator System.” The second case is primarily operating system-level intellectual property, and accuses Motorola of violating Apple’s patents on “Touch Screen Device, Method, and Graphical User Interface for Determining Commands by Applying Heuristics, Method and Apparatus for Displaying and Accessing Control and Status Information in a Computer System,” and “Supporting for Custom User-Interaction Elements in a Graphical, Event-Driven Computer System.”

Earlier this month, Motorola sued Apple in the US District Court for the Northern District of Illinois and the Southern District of Florida and also filed a complaint with the US International Trade Commission, saying that Apple had refused to buy licenses for Motorola technology despite length negotiations. In a separate action, Motorola also filed suit to prevent Apple from suing them for infringing 12 patents, even though Apple never accused Motorola of doing so. None of the 12 patents are a part of the lawsuit filed Friday.
