October 20, 2024 – CALB Group Co., Ltd., a leading battery technology company, has announced the filing of multiple lawsuits against CATL (Contemporary Amperex Technology Co., Ltd.) and several other prominent firms, including Tesla. The lawsuits allege the infringement of key battery-related patents owned by CALB. The legal actions have been initiated in both Hubei and Jiangsu Provincial High People’s Courts, with a combined compensation claim exceeding 1 billion yuan (approximately USD 140 million).
Patent Dispute Details
The latest legal dispute follows a long-standing rivalry between CALB and CATL, the world’s largest electric vehicle (EV) battery manufacturer. The focal point of these new lawsuits revolves around patents related to battery module technology, particularly innovations involving liquid cooling battery modules and assembly methods.
One of the four lawsuits specifically targets CATL and Tesla, accusing them of infringing CALB’s patent on “liquid cooling battery modules.” According to CALB’s statement, both CATL and Tesla’s Wuhan subsidiary have unlawfully produced and sold products that infringe upon their patented technology. CALB is seeking to halt all production and sales of the infringing products and is also demanding that CATL and Tesla destroy all related molds and equipment used in the production of these products.
For this particular lawsuit, CALB is seeking 5.6 billion yuan in economic damages and an additional 2 million yuan to cover legal expenses, totaling nearly 5.62 billion yuan in compensation.
Broader Legal Action Against CATL’s Subsidiaries and Other EV Manufacturers
Apart from the lawsuit involving Tesla, CALB has also filed three additional lawsuits against CATL and its affiliates. These cases concern a range of patents related to battery devices and assembly methods, including patents on “battery devices” and “battery packs.”
In these lawsuits, CALB has included CATL’s subsidiaries such as Sichuan Times, as well as other automakers like Avatr and Zeekr, accusing them of using the patented technology in their respective products. CALB has demanded similar remedies, including the cessation of production and sales of all infringing products and the destruction of associated production equipment.
A History of Legal Conflict
This latest round of legal action is not the first time that CALB and CATL have faced off in court. Their rivalry has been ongoing since 2021, when CATL first filed a lawsuit against CALB, accusing them of patent infringement. Over the course of nearly two years, this patent battle has seen various claims and counterclaims, with both parties accusing each other of unlawfully using proprietary battery technologies.
In August of last year, CALB announced that the National Intellectual Property Administration of China had invalidated two of CATL’s patents relating to lithium-ion battery technologies, which were central to CATL’s lawsuits against CALB. These developments marked a significant victory for CALB, although CATL remains the dominant player in the global EV battery market.
Implications for the EV Industry
The outcome of this ongoing legal battle could have far-reaching implications for the electric vehicle industry, particularly in China, where both CALB and CATL are key players. As the global demand for EVs continues to rise, battery technology and related intellectual property have become increasingly critical factors for success in the industry.
Patent disputes like those between CALB and CATL underscore the importance of innovation and the protection of proprietary technology in the highly competitive EV battery market. Furthermore, these lawsuits could lead to supply chain disruptions, as automakers like Tesla and Zeekr may be forced to adjust their manufacturing processes or find alternative suppliers if CALB’s claims are upheld in court.
Conclusion
As of now, CALB’s legal actions against CATL, Tesla, and other firms continue to unfold, with the potential for more lawsuits to arise as the EV battery industry remains fiercely competitive. The total damages sought by CALB, which exceed 1 billion yuan, reflect the high stakes involved in protecting intellectual property in one of the world’s most rapidly growing industries.
For now, the industry will watch closely as this high-profile legal battle between two of China’s most influential battery manufacturers plays out in the courts, with the outcome likely to shape the future landscape of EV battery technology.
