The US International Trade Commission (USITC) has launched an investigation into LG Electronics after a patent infringement claim from Sony.
LG Electronics's digital televisions and personal computer monitors from South Korea and America are under investigation.
The ITC said, "The investigation is based on a complaint filed by Sony Corporation of Japan on February 9, 2011. The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain display devices, including digital televisions and monitors, that infringe patents asserted by Sony."
Section 337 of the Tariff Act of 1930 is designed to tackle unfair practices concerning intellectual property rights. If product imports violate section 337, an exclusion order will prevent those products from entering the US.
LG filed a complaint against Sony in February over Blu-ray electronic devices and digital televisions. Tens of thousands of Sony Playstation 3 game consoles were seized in the Netherlands after LG won a court injunction.
An administrative law judge will decide if there has been a violation of section 337. After 45 days, the ITC will set a deadline for the completion of the investigation, which usually takes a year.
