On April 23, the Financial Times reported that the patent holders of a now-defunct Israeli startup have filed allegations against NIO, accusing the company of infringing on their intellectual property rights and seeking $250 million in damages. The Israeli company, once a trailblazer in electric vehicle infrastructure development, had patents related to battery swap technology. Charge Peak, a firm controlled by Canadian businessman Larry Krause, has sent a cease-and-desist letter to NIO concerning three European patents. In the letter, Charge Peak proposes a compensation benchmark set at 2% of NIO's projected 2025 revenue.

NIO, however, has denied these infringement allegations. The company asserts that its battery swap station technology exhibits significant differences from the patents cited in the lawsuit. Moreover, NIO has applied for over 2,200 related patents and has vowed to take appropriate legal measures to safeguard its intellectual property rights.
