Samsung Electronics Co has filed patent lawsuits against Apple over the U.S. firm's iPhone and iPad in a tit-for-tat case after Apple claimed Samsung's smartphones and tablets "slavishly" copied its products.



From Reuters:

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.
