Apple is claiming that the Samsung Galaxy S4 smartphone is violating five of their patents. Apple is pushing to have the S4 added to an ongoing legal battle between Apple and Samsung. The lawsuit is being heard at the U.S. District Court, Northern District of California, San Jose Division. The S4 was announced in March and went for sale in late April.
“Apple obtained the Galaxy S4 on April 27 and immediately began its infringement analysis, including Samsungs customizations of the Android Jelly Bean platform, covering the eight asserted patents,” said Apple in the filing. “That analysis revealed that the Galaxy S4 infringes five of Apples asserted patents in the same ways as Samsungs already accused products.”
Apple said that the S4 is infringing on two patents that are related to user interfaces, two related to Siri, and one related to data synchronization. Apple said that the infringement analysis focuses on Google’s functionality that Samsung incorporates into their devices. The two Siri related patents have to do with Google Now.
Apple has been reviewing confidential source code made available for inspection by the two companies since June 2012 to determine if Samsung and Google was violating their patents. Apple said that they encountered problems with the review because Samsung made the source code available for inspection on computers connected to a live copy of Samsung’s development servers in Korea. The servers that Apple was provided with the source code for released versions and also provided them with a window of the ongoing development process. This made the review process complicated. There was constantly-changing versions of unreleased source code and works-in-progress provided to Apple, reported PCWorld.
Apple also said that there were server outages and delays in downloading the source code, which prevented them from reviewing the relevant accused code. Apple and Samsung finally agreed to make a local copy of around 1.9TB of source code available to Apple. Apple also asked Samsung to correlate their source code with the “accused products.” Apple was able to match their analysis of the source code produced by Samsung to those products as well.
