Samsung files lawsuit against Apple over iPhone 5

Seoul: Samsung Electronics said on Tuesday that it filed a new lawsuit against Apple Inc in a US court, contending the iPhone 5 infringed on Samsung's patents.

In a statement, Samsung said: "...we have little choice but to take the steps necessary to protect our innovations and intellectual property rights."

Last week, a US appeals court ruled that a lower court should reconsider a sales ban against Samsung's Galaxy Tab 10.1 won by Apple in a patent dispute with the South Korean electronics maker.

The world's top two smartphone makers are locked in patent disputes in 10 countries as they vie to dominate the lucrative market, which is growing rapidly.
