Non-Practicing Entity Accuses Porsche of Patent Infringement

Non-Practicing Entity Accuses Porsche of Patent Infringement

On Tuesday, Norman IP Holdings filed suit [complaint] against Porsche Cars North America, accusing the automaker of patent infringement.

The Patents

Norman IP's lawsuit against Porsche is based on several patents, including:

  • Patent No. 5,530,597 for "Apparatus and Method for Disabling Interrupt Masks in Processors or the Like;"
  • Patent No. 5,502,689 for "Clock Generator Capable of Shut-Down Mode and Clock Generation Method;"
  • Patent No. 5,592,555 for "Wireless Communications Privacy Method and System;"
  • Patent No. 5,608,873 for "Device and Method for Interprocessor Communication Using Mailboxes Owned by Processor Devices;" and
  • Patent No. 5,771,394 for "Apparatus Having Signal Processors for Providing Respective Signals to Master Processor to Notify that Newly Written Data can be Obtained from One or More Memories."

The Infringement

Norman IP underscores the following Porsche systems in support its infringement claims:

  • Porsche infotainment systems (e.g., Porsche infotainment systems containing multimedia chipsets, for example, the Porsche Communication Management (PCM) 3.1 found in the 2012 991 Porsche 911 Carrera (which incorporates an ARM Cortex A9);
  • PCM equipped in other Porsche vehicle ( including other variants of the 911);
  • cellular and 802.11-compliant chipsets associated with telematics functionality (e.g., the chipset associated with the quad-band GSM telephone module within the Porsche Communication Management system; online service access via PCM);
  • safety systems (e.g., Lane Change Assist; Central Locking System); 
  • automotive navigation systems (e.g., Harman factory-installed navigation systems); and
  • automotive microcontrollers (e.g., Bosch ME and MED engine control units; ARM, MIPS, Freescale, ST, or Infineon embedded processors).

Similar Patent/Automotive Litigation

This isn't Norman IP's first automotive IP lawsuit in the Eastern District of Texas. Norman IP is already involved in active litigation against several automotive companies, including BMW, Mercedes-Benz, Ford, General Motors and Volkswagen. In that lawsuit [complaint], Norman IP is asserting the same patents asserted in the recent Porsche filing.
