As the global energy transition accelerates, China’s photovoltaic industry is entering a new phase marked by higher quality and innovation-driven growth. Chint New Energy Technology Co., Ltd. (hereinafter referred to as “Astronergy”) and JA Solar Technology Co., Ltd. (hereinafter referred to as “JA Solar”), as key industry promoters, have consistently prioritized technological innovation, increased investment in R&D, and strengthened their global intellectual property portfolios. Both parties are committed to fostering a market environment that upholds and safeguards intellectual property rights. Both companies remain committed to advancing PV technologies and supporting the sector’s long-term sustainable development.
Building on mutual agreement, on November 29, 2025, Astronergy and JA Solar jointly announced that the two companies and their affiliates (hereinafter referred to as “Two Sides”) have reached a settlement regarding the patent disputes currently ongoing worldwide.
Under the terms of the agreement, the Two Sides agree as follows:
· All ongoing legal proceedings relating to patent disputes worldwide shall be terminated;
· The Two Sides have reached an agreement on cross-licensing of TOPCon-related patents owned by each side;
· For the term of the agreement, the Two Sides undertake that, in the future, neither shall initiate any litigation or other proceedings against the other in any jurisdiction worldwide in relation to TOPCon-related patents.
The successful conclusion of this settlement reflects the Two Sides’ commitment to integrity, innovation, mutual benefit, and pragmatic cooperation. It sets a positive example for establishing a healthy and sustainable intellectual property cooperation model within the industry. Moving forward from this new starting point, the Two Sides will continue to focus their efforts on strengthening R&D in cutting-edge technologies, promoting the commercialization and application of high-efficiency PV technologies, driving scenario-based technological innovation, and jointly exploring deeper and broader strategic collaboration.
We believe this outcome will help foster a healthier and more orderly innovation environment across the industry, encourage fair and dynamic competition, and contribute to building a well-regulated and sustainable intellectual property landscape. Together, we aim to support global energy transition and contribute to a low-carbon future.
