Shenzhen Sunlord Electronics Co., Ltd. (Stock Code: 002138, Stock Abbreviation: Sunlord Electronics) recently announced the progress of litigation, revealing that out of three patent infringement disputes involving the company, one plaintiff has withdrawn the case, and the other two are still under trial.

The announcement shows that Murata Manufacturing Co., Ltd. previously filed three lawsuits with the Shanghai Intellectual Property Court, alleging infringement of invention patents against Sunlord Electronics and Shanghai Xuchin Electronic Technology Co., Ltd. The case numbers are (2025) Hu 73 Minchu 277, 278, and 279. Sunlord Electronics received the relevant litigation materials on November 6, 2025, and has disclosed them.

According to the latest update, on March 18, 2026, Sunlord Electronics received a Civil Ruling from the Shanghai Intellectual Property Court, approving the withdrawal of the case (2025) Hu 73 Minchu 277 filed by Murata Manufacturing Co., Ltd. The case acceptance fee of 50 RMB was halved to 25 RMB, to be borne by the plaintiff. As of the date of this announcement, the cases (2025) Hu 73 Minchu 278 and 279 are still under trial.

Sunlord Electronics stated that it does not recognize the claims made by the plaintiff and will actively respond. The company has always respected intellectual property rights and is committed to building its own IP system. In 2025, R&D investment reached 619 million RMB, a year-on-year increase of 22.73%. As of December 31, 2025, the company held 992 valid patents. Since two of the cases are still under trial, the impact of this litigation on the company’s current or future profits is uncertain, and the final actual impact will be subject to court rulings.

As of the date of this announcement, the company and its subsidiaries have no other major lawsuits or arbitration matters that need to be disclosed but have not been disclosed. The company’s board of directors will closely monitor the progress of the cases and fulfill its information disclosure obligations in a timely manner.
