Samsung has filed yet another lawsuit against Apple in South Korean, as the bad blood between the firms shows no signs of subsiding.
"Samsung has today filed a lawsuit against Apple in the Seoul Central District Court over its continued infringement of three utility patents in its iPhone 4S and iPad 2," Samsung said in a statement.
"This lawsuit is separate from the proceedings filed against Apple in Seoul in April 2011 regarding infringement of telecommunications standards-related patents."
Apple had not responded to a request for comment at the time of publication.
The fresh lawsuit comes four months after the launch of the iPhone 4S and signals Samsung's intent to try and gain an upper hand over its key rival in its home market.
Samsung has been on a roll, selling over 20 million of its Galaxy S II devices, which uses the Android operating system.
It is likely that this latest courtroom battle will drag on for months, like many of the other cases as both sides appeal and counter appeal decisions.
There are over 30 cases pending between the firm's respective tablet and smartphone ranges and they span the entire globe ranging from South Korea and Europe to the US.
Apple is also involved in high-profile battles with other Android manufacturers and was handed a boost in its US patent case against Motorola on Tuesday.
A US Judge has ordered Motorola to hand Apple information about the development of Android. Apple has also been granted access to details about Google's $12.5bn takeover of Motorola, which it may use in its case, according to a report on Bloomberg.
