Taiwan Semiconductor Manufacturing Co. (TSMC) has purchased 178 U.S. patents from non‐practicing entity (NPE) Daedalus Blue LLC.
The deal, executed in two separate transactions—85 patents acquired in November 2023 and an additional 93 patents in June 2024—spans a broad array of technology categories.
The acquired patents cover innovations in computing infrastructure and virtualization/system management; data management and analytics; communications, messaging and collaboration; user interface and interaction; security and access control; network and infrastructure management; energy, cooling and power management; multimedia and content delivery; and IoT, sensor and robotics systems.
Daedalus Blue has an extensive litigation history in the United States, having filed patent infringement lawsuits against DJI, Oracle, MicroStrategy, Microsoft, and Dropbox. While lawsuits against DJI, MicroStrategy, and Dropbox remain pending, Daedalus Blue has never initiated patent disputes against TSMC.
In a related note, Daedalus Prime LLC—sharing the same address as Daedalus Blue—has previously brought lawsuits against TSMC, MediaTek, Samsung Electronics, Mercedes Benz AG, and Mazda Motor Corp. Specifically, Daedalus Prime filed three patent infringement actions against TSMC in the United States between 2022 and 2023, all of which had been resolved by February 2025. Notably, from 2021 to 2023, Daedalus Prime transferred 193 U.S. patents from Intel.
