Motorola v. Apple (2010, USA)

Revision as of 23:24, 16 January 2012 by Ciaran (Talk | contribs)

Jump to: navigation, search

In early October 2010, Motorola accused Apple of infringing 18 patents and filed suit in the USA in Northern Illinois and Southern Florida federal district courts.[1]

On the 30th October, Apple filed a counter-suit in the USA,[2] initially listing 12 patents allegedly infringed, and later amending the suit to list 24 patents.[3] 21 are for distribution of Android software, 3 for set-top box video recorders.[4] Apple also applied to the United States International Trade Commission asking for an import ban on certain Motorola products, but this was rejected in January 2012.[5]


The patents

(Can you help? How many are software patents? (See: Definition of software patent).)

Motorola accuses Apple of infringing 18 patents,[6] some of which seem to be software patents.

Those which are or might be software patents

  • 5,311,516: Paging system using message fragmentation to redistribute traffic
  • 5,319,712: Method and apparatus for providing cryptographic protection of a data stream in a communication system
