LG Energy Solution is significantly intensifying its patent enforcement efforts against global automakers, applying pressure across the entire electric vehicle (EV) supply chain to safeguard its pioneering core battery technologies, according to recent industry insights.
The leading battery manufacturer has recently initiated legal action, filing for an injunction against Volvo Car Korea. The claim alleges patent infringement concerning the batteries utilized in the highly anticipated electric SUV, the Volvo EX30.
These specific batteries, identified as prismatic nickel-cobalt-manganese types, are supplied by China’s Sunwoda, a firm now at the focal point of LG Energy Solution’s robust legal strategy.
In a parallel move, LG Energy Solution, working through its dedicated patent management partner, Tulip Innovation, lodged a formal complaint with Korea’s Trade Commission under the Ministry of Trade, Industry and Resources. This complaint requests a thorough investigation into alleged unfair trade practices, prompting authorities to officially launch a probe into the matter.
Expanding its global reach, Tulip Innovation has also filed a similar injunction in Germany. This action targets Nissan’s popular hybrid SUV, the Qashqai, asserting that its Sunwoda-supplied batteries infringe upon the very same foundational patents.
Central to these widespread disputes is a critical patent that protects an innovative electrode assembly structure. This core battery technology involves integrating electrode layers with a specialized coated separator, a design proven to significantly enhance battery stability. This advanced technology is extensively deployed in high-capacity, high-output batteries essential for modern electric vehicles and sophisticated energy storage systems.
LG Energy Solution’s patent enforcement has already seen significant success; Tulip Innovation previously secured a favorable ruling in Germany against Sunwoda concerning this identical patent. This landmark decision resulted in a sales ban and a product recall order, alongside additional victories in related cases involving proprietary separator coating technology.
Further demonstrating its commitment to protecting its intellectual property, LG Energy Solution, through Tulip Innovation, filed another complaint in February with Korea’s Trade Commission. This latest action alleges patent infringement within the battery packs used in Renault’s Grand Koleos SUV, signaling a sustained and broadening legal offensive.
With an extensive portfolio of fundamental patents spanning critical areas such as battery materials, electrode assembly designs, and comprehensive battery packs, LG Energy Solution is unequivocally poised to escalate its patent enforcement activities globally.
The company’s formidable intellectual property strength is underscored by its holdings as of end-2025: over 51,000 registered patents and approximately 90,000 pending applications, including more than 1,000 classified as strategic patents vital to the future of EV battery technology.
