Samsung said it filed a suit April 21 in the Seoul Central District Court, Korea against Apple Inc., citing five patent infringements.
Samsung also filed separate lawsuits in Tokyo, Japan, and Manheim, Germany, claiming additional infringements. Samsung's statement said, "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."
