Samsung Electronics has filed a patent infringement suit in China against Huawei, adding fuel to a legal battle between the rival smartphone makers. In the suit filed in a Beijing court, Samsung demanded millions of dollars in compensation from the Chinese firm for allegedly stealing its mobile imaging and data storage technology.

"Despite our best efforts to resolve this matter amicably, it has regrettably become necessary to take legal action in order to defend our intellectual property," Samsung said in a statement.

The move came after Huawei had filed a similar suit in a US court in May, accusing Samsung of stealing patents on wireless connectivity for handsets.
