Samsung Countersues Apple For Patent Infringement

The Apple-Samsung patent battle just got murkier, with Samsung filing counter lawsuits in South Korea, Japan and Germany.

The Samsung lawsuits, which cited infringement of five Samsung patents related to mobile communication technology by Apple, come just days after the Mac OS X maker accused its rival of copying designs from the iPhone and iPad.

The legal battle that is unfolding is the latest among a series of patent infringement suits from companies in the increasingly competitive smartphone and tablet PC market.

Samsung, which has been an Apple supplier for a long time, released the Galaxy S and Galaxy Tab series of smartphones and tablets based on Google’s Android operating system to compete with the iPhone and the iPad.

Apple acknowledged that Samsung was its largest supplier of LCD screens and semiconducter chips but added that it had ‘crossed the line’, prompting it to file a lawsuit.

Samsung on the other hand believes that Apple is trying to keep it in check as its products are giving the iPhone and iPad serious competition.

"Samsung is responding 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.
