Battery Giants Clash: CATL Sues CALB for Patent Infringement, Escalating Tech War

Introduction

The electric vehicle (EV) battery market, a fiercely competitive arena where innovation and intellectual property are paramount, is witnessing a renewed escalation of hostilities between two of its major players. Contemporary Amperex Technology Co. Limited (CATL), the world’s largest battery manufacturer, has launched a fresh patent infringement lawsuit against China Aviation Lithium Battery Co., Ltd. (CALB), a rapidly growing rival. This legal action, seeking 91 million yuan (approximately $12.7 million) in damages, marks the latest chapter in a long-simmering dispute that underscores the high stakes and intense rivalry within the burgeoning battery industry. The case not only highlights the importance of intellectual property in this sector but also signals the potential for further legal battles as companies strive to protect their technological advancements and market share.

The Lawsuit: Details and Claims

CATL’s lawsuit, filed with the Hangzhou Intermediate People’s Court, accuses CALB and its sales partner, Hangzhou Pengxing Automobile Sales Service Co., Ltd., of infringing on its patents related to secondary battery top cover components and related inventions. The core of the accusation revolves around the alleged unauthorized use of CATL’s proprietary technology in the manufacturing and sale of CALB’s battery products.

Specifically, CATL is demanding that CALB immediately cease all activities that infringe upon the disputed patents. This includes halting the production, sales, and marketing of the products in question. Furthermore, CATL is seeking substantial financial compensation, claiming 90 million yuan in economic losses and an additional 1 million yuan to cover the legal costs associated with pursuing the case. This total demand of 91 million yuan reflects the significant financial impact CATL believes it has suffered due to the alleged infringement.

CALB’s Counter-Move: Challenging Patent Validity

In response to CATL’s lawsuit, CALB has swiftly initiated a counter-offensive. The company has announced that it has filed a request with the National Intellectual Property Administration of China (CNIPA) to invalidate the patents at the center of CATL’s claims. This move is a strategic maneuver aimed at undermining the legal basis of CATL’s lawsuit. By challenging the validity of the patents, CALB hopes to not only avoid paying damages but also to continue producing and selling its products without further legal impediments.

The acceptance of CALB’s invalidation request by CNIPA is a crucial development. It suggests that there is at least some merit to CALB’s challenge and that the validity of CATL’s patents is not a foregone conclusion. This process could take several months, or even years, to resolve, adding a layer of complexity to the already intricate legal battle.

CALB has also stated that it will take all necessary legal measures to protect its legitimate rights and interests and will keep the market informed of the progress of the litigation. This statement indicates a firm commitment to defending its position and a willingness to engage in a protracted legal battle if necessary.

A History of Conflict: The Underlying Rivalry

The current lawsuit is not an isolated incident but rather the latest skirmish in an ongoing conflict between CATL and CALB. The two companies have a history of intellectual property disputes, reflecting their fierce competition in the rapidly expanding EV battery market.

As the saying goes, two tigers cannot share the same mountain, and this adage aptly describes the relationship between CATL and CALB. The two companies have been locked in a battle for market share and technological dominance, and intellectual property disputes have become a key battleground.

CATL’s Initial Offensive: In July 2021, CATL launched a series of six patent infringement lawsuits against CALB, seeking a total of approximately 700 million yuan in damages. These initial lawsuits marked the beginning of the current legal conflict and signaled CATL’s determination to protect its intellectual property. The lawsuits covered a range of battery technologies, highlighting the breadth of CATL’s patent portfolio and its willingness to aggressively enforce its rights.
CALB’s Counter-Suits: In October 2024, CALB responded to CATL’s legal actions by filing four lawsuits of its own, accusing CATL and related companies of infringing on its patents. CALB is seeking a total of 1.007 billion yuan in damages from CATL, demonstrating its willingness to fight back against what it perceives as unwarranted attacks on its intellectual property.

The most significant of CALB’s lawsuits involves a patent related to liquid-cooled battery module technology. This lawsuit targets CATL and Tesla Automobile Sales Service (Wuhan) Co., Ltd., alleging that the two companies have infringed on CALB’s patent by manufacturing and selling products that incorporate this technology. CALB is demanding that both companies cease their infringing activities and pay 560 million yuan in economic losses, as well as 2 million yuan for legal expenses.

CALB’s counter-suits are widely seen as a direct response to CATL’s earlier legal actions and a clear indication that CALB is not willing to be intimidated by its larger rival. These actions have transformed the conflict from a one-sided assault by CATL to a full-fledged legal battle between two industry giants.

The Stakes: Market Share and Technological Leadership

The patent disputes between CATL and CALB are not just about legal technicalities; they are fundamentally about market share and technological leadership in the highly competitive EV battery market.
