Infineon obtient l’interdiction des composants GaN d’Innoscience aux États-Unis
美国国际贸易委员会（ITC）近日在氮化镓（GaN）专利诉讼中作出最终裁决，确认了2025年12月的初裁结果，判定英飞凌（Infineon）胜诉。据此，ITC对美国市场发布排除令，禁止Innoscience（英诺赛科）进口与销售侵犯英飞凌相关专利的GaN功率器件。
该禁令直接切断了Innoscience涉诉产品进入美国供应链的可能，涉及的GaN器件广泛应用于快充、数据中心电源、电动汽车等领域。英飞凌在声明中强调此举有助于维护其多年研发投入，而Innoscience尚未公开回应。在美国严苛的337调查框架下，此案凸显了宽禁带半导体领域专利竞争的激化，也对正在布局美国市场的中国GaN企业形成显著风险。由于ITC禁令为最终裁定，除非美国总统在60天内因公共政策原因否决，该排除令将即时生效。
The U.S. International Trade Commission (ITC) has ruled in favor of Infineon Technologies in a patent dispute involving gallium nitride (GaN) power semiconductors, ordering a ban on the importation and sale of infringing components made by Chinese manufacturer Innoscience in the American market. The final decision, confirming a preliminary ruling from December 2025, stems from Infineon’s allegations that Innoscience unlawfully used its patented GaN technology.
While the specific patent numbers and product lines were not enumerated in the ruling’s immediate announcement, the prohibition effectively blocks Innoscience from supplying a range of GaN-based transistors, integrated circuits, and related devices to U.S. customers. This enforcement action under Section 337 of the Tariff Act highlights intensifying intellectual property battles in the fast-growing GaN chip sector, where Infineon holds significant foundational patents. Innoscience now faces the possibility of a permanent exclusion order, forcing it to either design around the patents, seek a license, or abandon the U.S. market for those components.
La Commission du commerce international des États-Unis a donné raison à Infineon dans un litige sur des brevets liés au nitrure de gallium. L’ITC ordonne l’interdiction d’importation et de vente des produits concernés d’Innoscience sur le marché américain. La Commission du commerce international des États-Unis (ITC) a confirmé sa décision initiale rendue en décembre 2025 […]
