Ebay Inc. v. Mercexchange, L. L. C.

Summary

Chief Justice Roberts concurred in the Court's holding that the decision to grant or deny injunctive relief rests within the equitable discretion of district courts consistent with traditional principles of equity. He agreed that historical practice does not entitle a patentee to a permanent injunction or justify a general rule. Justice Kennedy, joining the Court, wrote separately to note that courts should consider the economic function of patent holders, particularly in cases involving licensing fees or business methods.
