Adding to its lawsuits against Apple in three other countries, Samsung has filed another against the iPhone and Mac maker, this time in the U.S.
The suit, filed yesterday in the U.S. District Court for the Northern District of California San Jose division, and picked up by Bloomberg, accuses Apple of infringing on 10 of its patents. One of those patents includes the capability to use the Web while on a phone call, a feature Apple's touted in its advertisements for the GSM version of the iPhone.
The suit targets iPhones going all the way back to the 3G, as well as the iPod Touch, and first- and second-generation iPads. Samsung is seeking damages caused by Apple for its alleged infringements in these devices.
Apple launched a multi-prong lawsuit against Samsung earlier this month, claiming the company was infringing on its patents, as well as copying Apple's design and other intellectual property. Apple's suit takes aim at Samsung's Galaxy series of smartphones and tablets, as well as other devices made by the South Korea-based company. Samsung responded in kind last week, launching lawsuits against Apple in Tokyo; Manheim, Germany; and Seoul South Korea.
"Samsung is continuing to respond actively to the legal action taken against us in order to protect our intellectual property and to ensure our continued innovation and growth in the mobile communications business," the company said in a statement released to CNET.
An Apple representative declined to comment on the latest suit, instead referring to the claims made against Samsung in its filing earlier this month.
As mentioned in previous coverage, Apple and Samsung are longtime business partners, with Apple once investing millions into the company's display business. During Apple's quarterly earnings call last week, Apple COO Tim Cook noted that the company was Samsung's largest customer and that Samsung was "a very valued component supplier for us." Apple's suit specifically targets Samsung's mobile communications business.
