LG Energy Secures Victory in Third Legal Battle Against Chinese Battery Company over Alleged Patent Infringement
LG Energy Solution Wins Third Consecutive Patent Infringement Lawsuit Against Sunwoda
In a series of legal battles, LG Energy Solution, a leading battery manufacturer, has secured its third victory against Chinese battery maker Sunwoda in Germany. The disputes revolve around patent rights for advanced battery technologies, highlighting the intensifying global competition in this critical sector.
The German court ruled that Sunwoda's prismatic batteries used in the Dacia Spring electric vehicle infringed LG Energy Solution's patents concerning electrode assembly and separator technology crucial for high-capacity, high-output lithium-ion batteries. The court ordered a sales ban on the infringing batteries in Germany, the recall and destruction of existing stock, provision of accounting information, and payment of damages. However, Sunwoda retains the right to appeal.
These legal victories, enforced through Tulip Innovation—a patent management and licensing agent for LG Energy Solution and Panasonic Energy—reflect LG Energy Solution’s strategic effort to protect its extensive portfolio of over 5,000 patents in battery technology. The specific disputed patents focus on electrode arrangements and complex separator arrangements that maintain battery durability and performance, technologies widely adopted in electric vehicles and energy storage systems.
In May 2020, LG Energy Solution also won two separate patent cases against Sunwoda regarding its safety-reinforced separator coating technology.
The focus on a global market for patent licensing indicates LG Energy Solution’s ambition to address patent infringement on an international scale. The creation of a global battery patent licensing market could potentially level the playing field for all companies in the industry, ensuring fair competition.
The aggressive stance taken by LG Energy Solution against patent infringement may set a precedent for other companies in the battery industry. The identified infringing products span across different battery capacities and range from various sectors, indicating a widespread issue of patent violation.
As the electric vehicle industry continues to grow, securing patent rights for advanced battery technologies becomes increasingly important. The German courts are acting as key battlegrounds for enforcing these rights, with LG Energy Solution planning to respond firmly to the infringement of its patents through lawsuits and warnings.
