A California judge has ruled that claims from four messaging and social media patents asserted by BlackBerry are invalid under Alice. In an October 1 order issued in the company’s lawsuit against Twitter, District Judge George H. Wu held that two patents generally related to notification management are unpatentably directed to abstract ideas but granted the plaintiff leave to amend its complaint in order to add additional factual allegations regarding those patents. The court also declined to invalidate two other patents, one due to a factual dispute under Aatrix and the other due to its similarity to certain other patents previously upheld by the Federal Circuit. In addition, the order incorporated Judge Wu’s analysis from another sealed decision issued that same day in cases against Facebook and Snap in which the court invalidated a further two patents but left a third intact.
