China tightens intellectual property rules to shield solar innovations

China has taken new steps to protect intellectual property in its solar industry. The National Intellectual Property Administration (CNIPA) and the Ministry of Industry and Information Technology (MIIT) have released a guidance document outlining stricter measures for safeguarding innovations and managing risks.

The document highlights key areas for the solar sector, including supply chain security, patent protection, and risk control. It specifically calls for tighter customs enforcement to block the import and export of solar products that infringe on intellectual property rights.

Companies are being pushed to invest more in research and development, particularly in advanced technologies like TOPCon and heterojunction solar modules. They are also advised to secure foundational patents for emerging innovations such as perovskite and tandem batteries. The guidance urges faster patent reviews and quicker resolutions to disputes. It also encourages businesses to defend their intellectual property abroad, build stronger brand recognition, and address legal conflicts without delay. Over the past two years, the shift from Mono PERC to TOPCon technology has led to a rise in intellectual property disputes. To tackle this, the authorities are promoting better coordination between agencies and more efficient mediation and arbitration processes.

The new measures aim to strengthen China’s solar industry by protecting innovations and reducing legal conflicts. With a focus on faster patent approvals and stricter customs controls, the government hopes to secure the sector’s growth while encouraging companies to expand their global influence.
