IPValue Management (d/b/a IPValue) subsidiaries Longitude Licensing Limited and Marlin Semiconductor Limited (f/k/a Sandyford Semiconductor Limited) have begun litigating a portfolio of former United Microelectronics Corporation (UMC) patents with a pair of complaints: the first, against Apple, Broadcom, and Qualcomm (1:25-cv-00215) in the Western District of Texas; and the second, against Lenovo (Motorola Mobile Communication), OnePlus, and TSMC (2:25-cv-00171) in the Eastern District of Texas. The five patents-in-suit are broadly directed to various aspects of semiconductor fabrication. The defendants are accused of infringement through the provision and/or incorporation of semiconductor devices fabricated using “any of TSMC’s 16nm and smaller process nodes”, as well as “downstream products” (e.g., desktop computers, smartphones, smartwatches, tablets, and wearables) that incorporate such semiconductor devices.
