Marlin Semiconductor

Marlin Semiconductor Limited, an Irish entity founded in 2020 as Sandyford Semiconductor Limited before a name change in January 2021, is a non-practicing entity (NPE) and a subsidiary of IPValue Management, Inc.. IPValue Management, which focuses on patent monetization, has been owned by private equity firm Vector Capital since 2014. Marlin Semiconductor's primary business activity is holding or owning securities, rather than manufacturing or providing services.

Marlin Semiconductor's "operations" consist of acquiring and asserting patent portfolios. The company acquired over 800 worldwide patents and pending applications from United Microelectronics Corporation (UMC). These patents broadly cover various aspects of semiconductor structures, processes, and circuits, applicable to technologies such as advanced communication, infrastructure, cloud computing, memory, imaging, and processing technologies. Longitude Licensing Ltd., another IPValue subsidiary, acts as the exclusive licensee for Marlin Semiconductor's portfolio.

Marlin Semiconductor operates as a patent assertion entity, evidenced by its exclusive role as a plaintiff in tracked litigation. The company is currently engaged in a U.S. International Trade Commission (ITC) investigation (337-TA-1443), where it is asserting its acquired UMC patent portfolio against multiple prominent semiconductor and electronics companies. Alongside the ITC complaint, it has filed companion district court cases in patent-friendly venues like the Western and Eastern Districts of Texas.

The company's notable litigation includes Marlin Semiconductor et al. v. TSMC et al., filed in the U.S. International Trade Commission. This investigation and related district court cases target a range of companies, including TSMC, Apple, Broadcom, Qualcomm, Lenovo, Motorola Mobile Communication, and OnePlus, accusing them of infringing patents related to semiconductor fabrication. The defendants are alleged to infringe through semiconductor devices fabricated using TSMC's 16nm and smaller process nodes, as well as downstream products incorporating these devices, such as smartphones and wearables. TSMC and Apple have explicitly characterized Marlin Semiconductor as an NPE in their filings. Marlin Semiconductor has also successfully licensed its semiconductor portfolio to Samsung Electronics Co., Ltd..
