already asked the European Telecommunications Standards Institute for more transparency on FRAND licensing, and now it's seeking a full-blown intervention. Motorola Mobility claims it received a letter on Friday from the European Commission advising there has been a complaint against it from Apple. The letter also stated that Cupertino wants the Commission to enforce the firm's standards-essential patents that breach agreed FRAND commitments. This latest development comes just one day after a German court awarded Apple an injunction against Motorola's implementation of slide-to-unlock on smartphones, as well as an ongoing saga of similar disputes with the firm. It's also just days after the European Commission approved Google's acquisition of the handset maker, based on beliefs that it "does not itself raise competition issues."
