Aktualisiert: 9. Dez 2020


Munich, Oct.1st, 2020 – Per October 01, 2020 IPCom has filed patent infringement proceedings at the United States District Court for the Eastern District of Texas against three US major network operators: AT&T (AT&T Inc., AT&T Corp., AT&T Communications LLC, AT&T Mobility LLC, AT&T Mobility II LLC, AT&TServices Inc.), Verizon (Verizon Communications Inc., Cellco Partnership d/b/a/ Verizon Wireless, Verizon Business Networks Services, Inc., Verizon Services, Inc., Verizon Enterprise Solutions LLC, Verizon Business Global LLC, Verizon Business Services LLC, Verizon Corporate Services Group Inc., Verizon Data Services LLC, and Verizon Online) and Sprint (Sprint Spectrum, L.P. (d/b/a Sprint PCS), SprintCom, Inc., Sprint Communications Inc., Sprint Communications Company, L.P., Sprint Corporation, and Deutsche Telekom AG) for infringing patents essential to the technology used in 3G and LTE base stations standard. According to the complaints, AT&T infringes six standard-essential patents, and Verizon and Sprint – five standard-essential patents.

IPCom further announces that the infringed patents relate to:

  • a method of using SMS messages to convey specific messages of the MMS;

  • a communication protocol between a base station and multiple UEs;

  • uplink power control over a common dedicated channel in a CDMA system;

  • improving synchronization in code division multiple access (CDMA) systems (3G) using certain code sequences and formats;

  • transmitting station that generates and transmits a first message to a receiving station.

It´s the first time that IPCom is initiating patent litigation proceedings against network service providers in the US.


Currently IPCom is also involved in a case with another major network provider, Vodafone in the UK. IPCom will be submitting a reply to Vodafone’s appeal this month. Vodafone is appealing the High Court’s finding that IPCom’s patent was valid and essential to the 4G LTE standard, while IPCom is appealing in relation to the Court’s application of the Crown Use defence raised by Vodafone. The appeal hearing is scheduled to start on January 25th, 2021.
