This Note recommends federal courts grant anti-suit injunctions in SEP litigation only under a restrictive test, rather than maintaining the current variation by circuit, and further suggests that Congress should codify this test. In the event of an injunction spiral that might preclude litigation altogether, SSOs should require the parties arbitrate the dispute before experts at the World Intellectual Property Organization. Together, litigation and arbitration can help preserve the interconnected and technologically compatible system currently in place around the world.
