Five patents claimed infringed, two covering Google Now
Apple has filed its amendment to its ongoing courtroom battle with Samsung, adding the Galaxy S4 to its list of infringing devices, just as it told the US District Court in California last week. The filing specifically names five patents said to be infringed by the Galaxy S4 itself, two of which are apparently infringed by Google Now.
Of the patents, numbers 8,086,604 and 6,846,959, both titled "Universal interface for retrieval of information in a computer system," relate to the Siri voice assistant, according to patent analyst Florian Mueller. The remaining patents, "Graphical user interface using historical lists with field classes" under US Patent 5,666,502, "Asynchronous data synchronization amongst devices" under number 7,761,414, and a "System and method for performing an action on a structure in computer-generated data" for 5,946,647. This last patent was used by Apple against HTC at the ITC.
According to the filing, Apple picked up three different Galaxy S4 devices, one each from AT&T, Sprint, and T-Mobile, leading to believe "the Galaxy S4 product practices many of the same claims already asserted by Apple, and that the Galaxy S4 practices those claims in the same way as the already-accused Samsung devices." As the filing does not list the Galaxy S4 Google Edition, it is possible that Apple is waiting for it to be put on sale, in order to examine it for infringement.
It is also noted in the filing that the "Siri Patents" were originally infringed by the Android Quick Search Box. As Google has replaced it with Google Now, Apple wishes to update its arguments to include the voice-based search system instead.
