A major patent battle between Chinese and Japanese electronic component leaders has intensified. Sunlord Electronics, a top Chinese firm, has filed a countersuit against Murata Manufacturing Co., Ltd. in the Shanghai Intellectual Property Court. Sunlord accuses Murata of engaging in "malicious intellectual property litigation" and is seeking 1.5 million yuan ($210,000) in damages, a public apology, and legal fees.
The conflict stems from several previous patent infringement lawsuits Murata filed against Sunlord, involving claims totaling 2.5 million yuan. In its counterclaim, Sunlord asserts that Murata's legal actions were either baseless or pursued with clear malicious intent, forcing Sunlord to expend significant resources and disrupting its normal business operations. Sunlord, which invested 505 million yuan in R&D in 2024 and holds hundreds of patents, positions this move as a defense of its legitimate rights and innovative capabilities.
This countersuit marks a new, confrontational phase in the dispute. The court's eventual ruling on what constitutes "malicious litigation" could set a significant precedent for cross-border patent competition within the semiconductor and electronics component industries. It is being closely watched as a potential model for how domestic companies might respond to legal challenges from international rivals.

This aggressive legal countermove by Sunlord reflects a growing assertiveness among Chinese tech firms in complex international patent disputes. The outcome may influence strategic approaches to intellectual property defense and litigation tactics within the global electronics supply chain.
