The war between Samsung and Apple continues as Apple requests a United States Preliminary Injunction on Samsung’s Galaxy Nexus. The request was filed in a U.S. District Court for the Northern District of California on Thursday, and the documents were released Friday. FOSS Patents discovered that Apple is basing its request for an injunction on four recently granted patents:

  1. The “data tapping” patent that the ITC ordered an import ban against HTC.
  2. A patent related to Siri and unified search that must be a huge concern to Google with a view to its core business.
  3. A new slide-to-unlock patent that even had the head of the Taiwanese government profoundly worried.
  4. A word completion patent that provides major speed improvements for touchscreen text entry.

The second patent (seen above) concerns Apple’s Siri technology. Google has similar a voice technology, and Apple wants to slash the accurate but not as robust feature out of the picture. The third slide-to-unlock patent is something that Apple has been after for a while, based on earlier patents. Apple also recently sued Samsung in a separate lawsuit over the fourth autocorrect patent.

Will the injunction be granted? Probably not, but it is interesting to see Apple keep trying. A judge will make a ruling in the coming months.
