近日【光伏资讯】微信公众号（PV-info）了解到，据美国商业商业资讯businesswire消息，2月25日下午，美国光伏巨头FirstSolar宣布已向美国特拉华州地方法院正式起诉晶科能源及其关联公司，指控其侵犯First Solar持有的美国第9,130,074号专利（简称"'074专利"）。

该专利涵盖隧道氧化层钝化接触（TOPCon）晶体硅光伏电池的制造方法。

第一太阳能通过2013年收购TetraSun公司获得了美国TOPCon专利组合。该专利组合覆盖美国、澳大利亚、加拿大、中国、欧盟、中国香港、日本、墨西哥、马来西亚、新加坡、韩国、阿联酋和越南等司法管辖区，有效期持续至2030年及以后，并包含欧盟、日本、中国香港、阿联酋和越南等地的待审专利申请。2024年7月，第一太阳能宣布拥有TOPCon技术专利组合，并启动对多家领先晶体硅太阳能电池制造商的侵权调查。

"我们始终明确表示将积极捍卫在美国及全球的知识产权。令人遗憾的是，我们与晶科能源的沟通未能取得建设性成果，迫使我们不得不通过法律手段维护专利权。"第一太阳能执行副总裁、总法律顾问兼公司秘书杰森·丁博特表示，"基于其他太阳能电池制造商对我们侵权调查的反馈，我们确信拥有强大的TOPCon技术专利组合。此次对晶科能源的诉讼将再次表明，TOPCon太阳能电池制造商必须在知识产权法律框架内合规运营。"

TEMPE, Ariz.--(BUSINESS WIRE)--First Solar, Inc. (Nasdaq: FSLR) (“First Solar”) today announced the filing of a lawsuit against Shanghai-headquartered JinkoSolar and its related entities alleging infringement of First Solar’s US Patent No. 9,130,074 (the “‘074 Patent”). The ‘074 Patent covers methods of manufacturing Tunnel Oxide Passivated Contact (“TOPCon”) crystalline silicon (“c-Si”) photovoltaic (PV) solar cells. The lawsuit was filed in the United States District Court for the District of Delaware.

First Solar obtained the US TOPCon patents and related international counterparts through its 2013 acquisition of TetraSun, Inc. The patents include issued patents in the United States, Australia, Canada, China, the European Union, Hong Kong, Japan, Mexico, Malaysia, Singapore, South Korea, the United Arab Emirates, and Vietnam with validities extending to 2030 and beyond. The portfolio also includes pending patent applications in the European Union, Japan, Hong Kong, United Arab Emirates, and Vietnam. In July 2024, First Solar announced its ownership of the TOPCon technology patent portfolio and the launch of infringement investigations against several leading crystalline silicon solar cell manufacturers.

“We’ve been clear that we will actively defend our intellectual property rights in the US and internationally. Unfortunately, our interaction with JinkoSolar has been unproductive and left us with no choice but to enforce our patent rights through legal action,” said Jason Dymbort, Executive Vice President, General Counsel and Secretary, First Solar. “Given the responses we received from other solar cell manufacturers in connection with our infringement investigations, we believe we have a strong TOPCon technology patent portfolio. We expect that our lawsuit against JinkoSolar will reiterate the need for TOPCon solar cell manufacturers to operate within the well-defined framework of intellectual property law.”
