Motorola's request for injunctive relief is a different animal than the Apple request at issue in spacestation's comment. The denial of Motorola's request involves their own claim/classification of their patent as necessary for all cell phones and therefore subject to a fairly licensed classification (FRAND.) Posner seems pretty amenable to a mechanical license in that case, but Motorola failed to provide evidence of a fair price for such a mechanism. Further, he suggests Apple has invented around this patent anyway and it isn't actually 'necessary.'
