Back in 2011, Intellectual Ventures fired off a patent infringement complaint against Motorola Mobility in the District of Delaware.  That case is scheduled to go to trial early in 2014  But today, Intellectual Ventures upped the ante, announcing that it has filed a second patent infringement complaint against Google subsidiary Motorola Mobility, choosing this time to file in the Southern District of Florida (where Motorola has a facility, in Plantation, FL).

[Intellectual Ventures v Motorola Mobility (S.D. Fla.)]

IV has asserted a total of seven new patents against Motorola.  The accused functionality appears to include both technology standards and non-standard features of Motorola’s products.  The specific standards implicated by IV’s infringement claims are the IEEE 802.11 Wi-Fi standards, as well as certain ETSI/3GPP cellular standards (GPRS and LTE).

As a remedy for the accused infringement, IV is seeking damages, plus costs and attorneys’ fees (but no injunction).  The full list of patents asserted by IV is below, along with a brief description of the accused functionality:

  1. U.S. Patent No. 5,790,793, titled ”Method and system to create, transmit, receive and process information, including an address to further information.”  Motorola’s products implementing MMS (multimedia messaging service) technology are accused of infringing this patent.
  2. U.S. Patent No. 7,136,392, titled ”System and method for ordering data messages having differing levels of priority for transmission over a shared communication channel.”  Motorola’s products that comply with the IEEE 802.11n wireless networking standard are accused of infringing this patent.
  3. U.S. Patent No. 6,121,960, titled ”Touch screen systems and methods.”  Motorola’s products that use Google’s Android operating system are accused of infringing this patent.
  4. U.S. Patent No. 7,382,771, titled ”Mobile wireless hotspot system.”  Motorola’s products that provide “Wi-Fi hotspot access” via the IEEE 802.11n wireless networking standard are accused of infringing this patent.
  5. U.S. Patent No. 7,564,784, titled “Method and arrangement for transferring information in a packet radio service.”  Motorola’s products that comply with the ETSI General Packet Radio Service (GPRS) cellular standard are accused of infringing this patent.
  6. U.S. Patent No. 6,170,073, titled ”Method and apparatus for error detection in digital communications.”  Motorola’s products that comply with the ETSI 3GPP and/or 4G Long-Term Evolution (LTE) standards are accused of infringing this patent.
  7. U.S. Patent No. 7,848,353, titled ”Method, communication system and communication unit for synchronization for multi-rate communication.”  Motorola’s products that comply with the LTE standard are accused of infringing this patent.

It should come as no surprise to those familiar with Intellectual Ventures that IV was not the original assignee of the patents-in-suit — these patents have been assigned to IV over the years, with former owners of the patents including Nokia, Spyder Navigations (who, according to this site, is a Nokia-related “privateer” that was managed by IV), Ninety Portals, IPWireless, Inc., Intersil, Conexant, In Motion Technology, and Infologix, among others.
