LG Energy Solution and China’s Sunwoda have concluded a confidential licensing agreement that brings their two-year patent dispute to an end. The settlement, arranged by patent management firm Tulip Innovation—which represents both LG Energy Solution and Panasonic—will lead to the withdrawal of all pending lawsuits in Germany, China, and South Korea.

The deal follows a series of court victories for LG Energy Solution. Last year, a German court upheld infringement claims against Sunwoda, ordering a sales ban on batteries using LG’s technology, along with product recalls and damages. LG Energy Solution also obtained further enforcement actions in Europe based on other patents related to electrode assembly structures.

Under the terms of the settlement, LG Energy Solution will drop its unfair trade investigation in Korea, which had targeted electric vehicles equipped with Sunwoda batteries, including models from Volvo Korea and Renault. Both parties have agreed to keep the specific licensing terms confidential.

Sunwoda, founded in 1997, now ranks among the global top 10 electric vehicle battery suppliers, according to market researcher SNE Research. Industry observers suggest that growing patent risks in key markets likely prompted Sunwoda to pursue a settlement, especially as pressure mounted from automaker clients worried about supply disruptions.

LG Energy Solution has emphasized its commitment to protecting intellectual property and preventing “patent free-riding” by late-entry competitors. The company currently holds more than 56,000 registered patents and nearly 98,000 patent applications worldwide, making it one of the largest patent portfolios in the battery sector.

Following this agreement, LG Energy Solution and Tulip Innovation plan to continue expanding their global patent licensing program. They aim to reinforce a licensing market that recognizes the value of technological innovation and ensures that companies investing in research and development receive fair compensation. Industry experts view this settlement as a potential catalyst for more structured patent licensing practices across the battery industry.
