Procedural Posture

Application for Ex Parte Injunction / Ex Parte Hearing

Legal Issues

  1. 1 Whether anti-anti-suit injunction (AASI) should be granted to restrain InterDigital from seeking to block Amazon's claim for final RAND relief in UK proceedings
  2. 2 Whether the English court's jurisdiction requires protection from foreign anti-suit injunctions
  3. 3 Whether InterDigital's conduct is vexatious or oppressive

Ratio Decidendi

The court granted an interim anti-anti-suit injunction ex parte, finding it seriously arguable that InterDigital may imminently seek to restrain Amazon's pursuit of final RAND relief in the UK, which would undermine the English court's jurisdiction and could be vexatious or oppressive. The risk was real and imminent, justifying quia timet relief. The order was limited in duration to preserve the status quo until an inter partes hearing, and was carefully crafted to avoid interfering with substantive patent infringement proceedings in foreign courts.
