Trouble is brewing once again for Samsung (News - Alert) as it comes under fire for patent infringement. Now Korean company, LG, has filed a lawsuit against Samsung’s use of OLED (organic light-emitting diode) technology, which it has been using in its mobile phones.

Just a few months ago, Samsung faced one of the largest patient lawsuits from Apple (News - Alert) Inc. who sued for over $2 billion for alleged infringement of the iPhone (News - Alert) and iPad with Samsung’s Android technology smartphones. At the time, Apple claimed that Samsung owes “substantial monetary damages” for copying its technology. That lawsuit is still pending.

Meanwhile, LG filed a claim against the technology company claiming that it infringed on multiple patents it owns including the design of Samsung’s OLED panels, driver circuitry, and overall device design. The three devices that allegedly infringe the patents are Samsung’s Galaxy S3, the Galaxy Note phone/tablet, and the Galaxy Tab 7.7 tablet.

“The company filed a damage suit to protect its indigenous technologies that took an enormous amount of money and people to develop over a long period of time,” an LG official said at a press conference.

“Samsung has been using our patented OLED technologies without paying royalties. Then it spread rumors that LG Display has been failing to produce small-sized OLED screens used in mobile devices, which we through was unacceptable and intolerable,” added senior vice president of LG Display, Lee Bang-soo.

Although LG has not officially announced how much it’s seeking in damages, the company is reportedly suing in the billions. This lawsuit from LG comes only a few weeks after Samsung filed its own injunction against LG insisting that the company “consistently acquired [their] OLED technologies and other business secrets by inducing our researchers to transfer.” Basically, Samsung accused LG of stealing its technology and wanted an apology. Now it seems LG is fighting back with a lawsuit of its own.

Samsung has not released a comment regarding LG’s newly filed legal action or the status of its own lawsuit again LG.
