Samsung has filed counter patent lawsuits against Apple over the Cupertino firm's iPhone and iPad after Apple claimed Samsung's smartphones and tablets "slavishly" copied its products.
Samsung had earlier stated of planning to counter sue Apple, now on Friday the company said that Apple's iPhone and iPad infringe Samsung's 10 mobile technology patents and it called for Apple to stop infringing its technology and compensate the company.
Samsung said the suits, filed in South Korea, Japan and Germany, involved 10 alleged infringements of patents mainly involving power reduction during data transmission, 3G technology for reducing errors during data transmission, and wireless data communication technology.
"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 statement said.
The battle comes ahead of Samsung launching a new version of its successful Galaxy S smartphone next week in Korea, a key product for the world's No.2 handset maker to meet its target of 60 million units of smartphone sales this year.
Global technology companies are locked in a web of litigation as they try to defend their shares of the booming tablet and smartphone market.
Strong sales of the iPhone and iPad translate into more revenue for Samsung. Apple was Samsung's second-biggest client after Japan's Sony Corp last year, bringing in around 6.2 trillion Korean won ($5.7 billion) of sales, and is widely expected to become Samsung's top client this year.
