A US trade panel on Wednesday ruled in favor of South Korean battery maker LG Energy Solution Ltd. in a trade secret case and issued a 10-year import ban on some lithium-ion battery products by SK Innovation.

The US International Trade Commission affirmed a preliminary ruling delivered in February 2020 to support LG's claims that SK used stolen trade secrets to develop its electric vehicle batteries.

The ITC issued "a limited exclusion order" for 10 years to ban import of some lithium-ion batteries and its components by SK Innovation, but permitted shipment of components for domestic production of its clients, including Ford Motor, Volkswagen and Kia, considering "public interests."

The order permits SK Innovation to import components for domestic production of lithium-ion battery products for Ford Motor for four years and for Volkswagen for two years to allow them to transition to new domestic suppliers, the ITC said in the ruling.

It also allows SK Innovation to import articles for the repair and replacement of EV batteries for Kia vehicles that had been sold to US customers.

The final ruling deals a heavy blow to SK Innovation's plan to grab a bigger chunk of the growing EV battery market with a new factory on US soil but allowed it to avoid delivery failures to its clients.

SK Innovation has been building a factory in Georgia, to be completed by 2022, to provide EV batteries to Volkswagen and Ford and is building its second plant at the site. It has pledged to hire 2,600 people by 2024.

The commission's decision could jeopardize SK's promises to create American jobs and complicate US President Joe Biden's push to expand EV adoption under his Green New Deal initiative.

The Biden administration has 60 days to review the ruling.

Unless Biden vetoes the ruling, it becomes final.

SK Innovation said it will continue efforts to prevent the ITC's ruling from disrupting its US production plan by promoting the importance of its EV battery supply chain and jobs to be created at the Georgia plant during the presidential review.

"We will explore ways to protect our clients' interests during the presidential review period and afterwards," SK Innovation said in a press release.

LG Energy Solution, wholly owned by LG Chem Ltd., said the ITC's ruling acknowledged its claim that SK Innovation stole its trade secret related to rechargeable batteries and caused damage to the company.

The world's No. 2 EV battery maker supplies batteries to Tesla, General Motors, Volkswagen, Hyundai Motor and a number of other automakers. It already produces batteries in a plant in Michigan and is building another factory in Ohio to supply Utlium Cells, its battery joint venture with GM.

LG Energy Solution urged SK Innovation to accept the final decision and come to the negotiating table with a compromise that can satisfy its shareholders and investors.

“If (SK Innovation) does not provide a compromise that corresponds to misappropriation of the trade secret and that can satisfy our shareholders and investors, we will sternly engage in ongoing legal proceedings at home and abroad," LG Energy Solution said in a statement.

LG and SK are mired in tit-for-tat battery patent infringement disputes filed in the US in 2019, with decisions expected later this year.

LG could take advantage of its ITC ruling at the Federal District Court in Delaware, which can order the plaintiff to pay compensation for actual damages and higher punitive damages.

The two Korean companies have faced growing pressure from South Korean policymakers and politicians in Georgia to resolve the prolonged legal issues, but they have failed to reach a compromise due to a big gap on the settlement amount.

According to industry sources, LG demanded nearly 3 trillion won ($2.7 billion) in compensation, but SK offered less than 1 trillion won. (From news report)
