South Korean patent management company Mimir IP, which acquired approximately 1,500 chip-related patents from SK hynix in May, has filed a complaint against Micron, accusing the US memory giant of infringing on its chip-related patents, the Korea Economic Daily reported. Sources suggested that if Mimir wins the case, the damages could amount to as much as USD 480 million.

The Korea Economic Daily learned that the lawsuit, filed on June 3, also targets four other companies that use Micron products: Tesla, Dell, HP, and Lenovo, while the patents involved are reportedly related to circuits, voltage measurement devices, and non-volatile memory devices.

The case has been filed with both the US District Court for the Eastern District of Texas and the US International Trade Commission (ITC), which marks the first instance of a Korea-based non-practicing entity (NPE) that acquired patents from domestic chipmakers filing a suit against a US semiconductor company.

Officials from the involved parties were unavailable for comment, the report said.

SK hynix, the current market leader in HBM, has been facing heated competition from Samsung and Micron, both of which have recently developed their HBM3e chips, trying to win favor from the world’s leading AI chip designer, NVIDIA. Now it seems that the battleground for industry dominance is expanding from technology competition to patent disputes.

It is worth noting that transferring patents to non-practicing entity (NPE) has become more and more popular, as it seems to be a preliminary measure for companies to prepare for legal disputes with its competitors, the report noted.

The Big Three in the memory industry have made similar moves on their patent strategy recently. According to the report, Micron transferred over 400 chip-related patents to Lodestar Licensing Group in March, 2023, followed by Samsung, which transferred 96 US chip patent rights, including the right to file patent infringement complaints, to IKT, an affiliate of Samsung Display, in June 2023.
