China Issues Guidance on Strengthening Solar Intellectual Property Rights Protection
China's CNIPA and MIIT have issued guidance to strengthen solar industry intellectual property protection, focusing on enhanced patent creation quality, streamlined examination processes, and specialized dispute resolution mechanisms. The document prohibits import/export of infringing solar products, encourages increased R&D investment in advanced technologies, and establishes cross-agency coordination for comprehensive IP enforcement and overseas protection.

China's National Intellectual Property Administration (CNIPA) and Ministry of Industry and Information Technology (MIIT) have issued comprehensive guidance to strengthen intellectual property protection in the solar industry. The document establishes key tasks for solar companies and emphasizes protecting important supply chain links while enhancing risk management capabilities.
The guidance aims to stimulate intellectual property rights' role in building a modern solar industry system and supporting China's development as a manufacturing and intellectual property powerhouse. This initiative comes as the solar industry experiences increased patent disputes during the transition from Mono PERC to TOPCon technology.
Enhanced Patent Creation and Quality Standards
The guidance encourages solar enterprises to significantly increase research and development investment while accelerating technology advancements in critical areas. Companies must strengthen high-value patent layouts for TOPCon, back-contact, and heterojunction solar module technologies.
| Technology Focus Areas: | Requirements |
|---|---|
| Advanced Technologies: | TOPCon, back-contact, heterojunction modules |
| Future Technologies: | Perovskite and tandem batteries |
| Component Innovation: | Inverters, raw materials, equipment, system components |
| Integration Systems: | Photovoltaic-energy storage, intelligent management, operation and maintenance |
Solar companies must proactively reserve basic patents for advanced technologies and expand patent mining activities across upstream and downstream supply chain segments.
Streamlined Patent Examination Processes
The document establishes mechanisms to improve patent examination efficiency through national-level intellectual property protection centers. These centers will provide professional, efficient patent pre-examination services specifically for solar enterprises.
Key implementation measures include:
- Establishing intellectual property risk monitoring and early-warning mechanisms
- Providing enterprise guidance for intellectual property compliance management
- Conducting patent risk analysis to prevent infringement disputes
- Strengthening tracking and analysis of industry intellectual property risks
Specialized Dispute Resolution Framework
CNIPA and MIIT recommend that provinces with concentrated solar industries establish specialized mechanisms for efficient patent dispute resolution and administrative adjudication case handling. The guidance supports creating cross-regional joint trial mechanisms for solar patent infringement disputes.
| Dispute Resolution Components: | Implementation Details |
|---|---|
| Administrative Adjudication: | Efficient handling through specialized mechanisms |
| Cross-Regional Trials: | Joint mechanisms for patent infringement cases |
| Mediation Services: | Centralized litigation-mediation linkage mechanism |
| Industry Participation: | Associations and social organizations involvement |
Cross-Agency Coordination and Enforcement
The guidance establishes comprehensive information-sharing mechanisms between intellectual property management departments and industry authorities. Regular sharing of administrative adjudication case information will occur with industry and information technology authorities, state-owned assets supervision departments, and customs authorities.
Critical enforcement measures include:
- Strict adherence to solar manufacturing industry standards
- Dynamic management of compliant enterprise lists based on core patents
- Strengthened customs protection to prohibit import and export of solar products that infringe intellectual property rights
- Enhanced oversight of administrative rulings on intellectual property infringement
Overseas Protection and Brand Development
The document emphasizes enhancing overseas intellectual property rights protection assistance mechanisms for solar enterprises. Companies must improve intellectual property risk prevention during international exhibitions, product exports, and overseas investments.
Solar companies are required to actively cultivate positive images for Chinese brands while building internationally influential and well-known brands. This includes increased trademark protection efforts, monitoring overseas trademark use, and promptly handling overseas intellectual property disputes.
The guidance addresses growing intellectual property challenges as the solar industry transitions to advanced technologies, particularly following recent global settlements between major manufacturers like LONGi Green Energy Technology and JinkoSolar regarding patent disputes.
