3月3日，據外媒Mercom報道，隆基綠能在美國向晶科能源發起TOPCon專利訴訟，要求禁止晶科在美國銷售涉訴產品，并索賠經濟損失。

報道稱，中國光伏組件制造商隆基綠能（LONGi）已向美國德克薩斯州東區聯邦地區法院起訴晶科能源（Jinko Solar）及其子公司，指控其侵犯了專利權。

訴訟認為，晶科能源的隧穿氧化層鈍化接觸（TOPCon）技術及其他多款光伏組件產品侵害了隆基的美國專利。

隆基尋求法院頒布禁令，禁止晶科在美國銷售涉訴產品，并索賠經濟損失。此次訴訟是晶科此前起訴隆基專利侵權的法務反制措施，標志著兩家光伏企業間專利糾紛的升級。

截至2024年6月，隆基累計擁有3,166項授權專利，構建了涵蓋TOPCon等技術的多領域專利組合。隨著光伏行業從單晶PERC技術向TOPCon轉型，全球范圍內圍繞TOPCon技術的專利爭議顯著激增，中國、歐洲及美國已成為主要訴訟戰場。

去年，中國組件商天合光能（Trina Solar）曾在美國特拉華州聯邦法院起訴加拿大太陽能（Canadian Solar）三家美國子公司，指控其侵犯兩項TOPCon技術專利。對此，加拿大太陽能以訴訟缺乏依據為由予以駁回。

根據Mercom印度太陽能市場 leaderboard 2024年上半年數據，晶科能源與隆基綠能位列全球光伏組件供應商前兩名。

原文如下：

Chinese solar module manufacturer LONGi has filed a patent infringement lawsuit against Jinko Solar and its subsidiaries in the U.S. District Court for the Eastern District of Texas.

The lawsuit alleges that Jinko Solar’s tunnel oxide passivated contact (TOPCon) and multiple other photovoltaic module products infringe LONGi’s U.S. patents.

TOPCon technology is an advanced solar cell architecture that has gained popularity rapidly because it enhances energy yield and efficiency compared to the passivated emitter and rear cell (PERC) technology.

LONGi is seeking a court order to prohibit Jinko from selling the alleged infringing products in the U.S. and is also demanding financial compensation for damages.

The lawsuit follows Jinko’s infringement lawsuit against LONGi, making it a legal countermeasure in the ongoing patent dispute between the solar manufacturers.

LONGi held 3,166 authorized patents as of June 2024. The company has established patent portfolios across multiple technological fields, including TOPCon.

Patent disputes among solar companies have become more frequent recently, with intellectual property rights protection emerging as a key topic at major industry conferences.

The solar industry’s transition from Mono PERC technology to TOPCon has resulted in a recent surge of intellectual property disputes related to TOPCon, particularly in China, Europe, and the U.S.

Last year, Chinese module manufacturer Trina Solar filed a patent infringement lawsuit against three U.S. subsidiaries of Canadian Solar in the U.S. District Court for the District of Delaware.

The lawsuit claimed that Canadian Solar’s subsidiaries violated two of Trina’s U.S. patents on TOPCon technology. Canadian Solar has dismissed the lawsuit as frivolous.   Jinko Solar and LONGi Green Energy Technology were among the top solar module suppliers in 1H 2024, according to Mercom’s India Solar Market Leaderboard 1H 2024.
