Apple Inc. sued Samsung Electronics claiming Galaxy copies the iPhone and iPad.
"This kind of blatant copying is wrong," Apple spokeswoman Kristin Huguet said.
Samsung is one of the fastest growing smartphone makers and has emerged as Apple s strongest competitor in the booming tablet market with models in three sizes but it remains a distant second in the space. Samsung said it would respond to the legal action "through appropriate legal measures to protect our intellectual property."
Nokia and Apple have sued each other in numerous courts and as recently as last month Nokia filed a complaint with the U.S. trade panel alleging that Apple infringes its patents in iPhones, iPads and other products.
Apple is bringing 16 claims against Samsung, including unjust enrichment, trademark infringement and 10 patent claims.
