Notorious patent troll Uniloc has filed their third lawsuit in the last two months against Apple. The lawsuit, filed in the U.S. District Court for the Western District of Texas, claims that Apple is infringing on a Uniloc patent related to FaceTime’s backend systems. The company is seeking unspecified damages along with reimbursement of legal fees.
The patent in question is U.S. Patent 8,539,552. It was filed originally in 2003 and granted to 3Com. It was reassigned to Hewlett-Packard in 2013. It was signed over to Uniloc Luxembourg last year and transferred to Uniloc 2017 LLC in May.
The patent in question outlines a system and method for network based policy enforcement of intelligent client features. It was mainly focused at IP-based telephony systems but the patent is broad. It covers messaging policy enforcement and includes things like signaling, authentication, and routing from an intelligent device to a bace-end server where information is stored. Uniloc is claiming that Apple’s FaceTime uses this methodology that is laid out in this patented Intellectual Property (IP).
The suit claims that FaceTime on the iPhone 4 and later, iPad 2 and later, iPad mini, 4th generation iPod touch and later, and MacBooks running OS X or later utilize the infringing IP.
The suite is just the latest in a string that Uniloc has filed against Apple in the past year.
