Looks like Motorola's about to fight a legal battle on two fronts -- Apple on one hand, and Microsoft on the other. Microsoft fired the first shot last month with a nine-patent ITC complaint and a second salvo alleging that Motorola was charging unfair licensing fees for 802.11 WiFi and H.264 video last week, it's now Moto's turn to retaliate with a pair of legal complaints. The cellular company now claims that Redmond's infringing a total of sixteen patents with everything from Microsoft Exchange to Bing Maps to the Windows operating system itself -- as well as the aforementioned video codecs and wireless tech, of course. Moto's also determined to rub a little salt in the wound, it seems, as the company just pushed out a press release with the following statement: "It is unfortunate that Microsoft has chosen the litigation path rather than entering into comprehensive licensing negotiations, as Motorola has mutually beneficial licensing relationships with the great majority of technology companies industry-wide." PR after the break.
