On September 1, 2026, the patent management company Mimir IP filed a patent infringement lawsuit against MediaTek in the U.S. District Court for the Eastern District of Texas, alleging that its Dimensity, Helio, and Companio series system-on-chip (SoC) products infringe on four semiconductor-related patents.

Mimir IP is a South Korea-based patent management company classified as a non-practicing entity (NPE) that generates revenue by acquiring patents and engaging in litigation for licensing. In March 2024, Mimir IP acquired 1,021 U.S. patents from SK Hynix, bringing the total number of patents—including family patents in South Korea, China, and other regions—to 1,327.

The four patents specifically involved in this lawsuit originate from the U.S. patents Mimir IP acquired from SK Hynix, primarily including U.S. Patents Nos. 7,468,317, 7,755,954, 7,978,547, and 8,274,102. In its complaint, Mimir IP asserts that MediaTek, as a major competitor of SK Hynix—the original patent owner—should have been aware of the existence of all four patents as of their respective grant dates. Furthermore, Mimir IP alleges that MediaTek, knowing that the accused SoCs incorporated infringing features, nevertheless encouraged third-party manufacturers, distributors, and customers to import, sell, and use products containing these SoCs, thereby constituting “indirect and willful infringement.”

This marks the first time Mimir IP has named MediaTek as a defendant. Previously, in 2024, the company had initiated Section 337 investigations and parallel litigation against companies such as Micron, Dell, HP, Lenovo, and Tesla using patent assets acquired from SK Hynix. However, the motions to dismiss jointly filed by both parties in 2024, as well as the settlement agreement—which included a sublicensing arrangement between Mimir IP and SK Hynix and a direct patent license between SK Hynix and Micron—were ultimately withdrawn.
