South Korean authorities have raided Samsung corporate offices as part of an ongoing probe into leaked documents from rival LG.
According to Bloomberg, the documents focus on OLED panel technology. Authorities searched Samsung's offices to determine if LG partners leaked the documents to Samsung.
Samsung has denied any involvement in the leaks. The South Korean firm told Bloomberg that it wouldn't have any reason to steal technology from its competitors.
LG reported that it never linked Samsung to the leak and said the South Korean police made the connection independently.
Reports say the investigation has been ongoing since last July, with six LG Display employees already been charged with leaking the documents. LG said the information that the employees stole were widely known and not considered trade secrets.
OLED technology is used in electronic displays. The technology is used to create thinner and more energy efficient panels for use in televisions and smartphones.
The leaked documents specifically focused on OLED tech used in large television panels. Samsung is one of the world's largest television makers. However, the firm was late in introducing OLED televisions to the market. LG launched the technology in its television displays last January.
Corporate espionage has long been an issue in South Korea. In 1998, former employees of Samsung and LG were alleged to have sold stolen trade secrets to Taiwanese memory company Nanya Technology.
At the time of the allegations the South Korean government was derided for not having appropriate channels to prosecute corporate-espionage spies.
V3 reached out to Samsung and LG for comment on the news. Both firms were unavailable for comment at the time of publication.
