To confirm the specific filing date and the petitioner, further details would need to be accessed directly from the Unified Patents portal link provided in the patent record.

No other specific litigation cases (such as District Court or CAFC cases) directly involving US patent 8076194 are immediately apparent from the patent details, other than the general indication of "Family has litigation" and "First worldwide family litigation filed" which links to a Darts-ip page for the patent family. Further investigation of the Darts-ip platform for the specific patent US8076194B2, and additional searches on CAFC and PACER, would be necessary to identify any other relevant cases.

• Case Name: Certain Foreign-Fabricated Semiconductor Devices, Products Containing the Same, and Components Thereof (337-TA-1443).
• Plaintiff(s): Longitude Licensing Limited and Marlin Semiconductor Limited (subsidiaries of IPValue Management).
• Defendant(s): [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.), Broadcom Inc., Lenovo Group Limited, Motorola Mobile Communication Technology Ltd, Motorola (Wuhan) Mobility Technologies Communication Company Limited, OnePlus Technology (Shenzhen) Co., LTD., Taiwan Semiconductor Manufacturing Company Limited (TSMC), and Qualcomm Inc.

While the Google Patent page does not explicitly list 8076194 as one of the asserted patents, other sources indicate that Marlin Semiconductor is litigating a portfolio of former United Microelectronics Corporation (UMC) patents in this ITC investigation and companion district court cases, which are directed toward semiconductor devices and manufacturing technology. The patent 8076194 is part of this portfolio of former UMC patents acquired by Marlin Semiconductor.

3. U.S. District Court Cases (Companion to ITC 337-TA-1443)

• Plaintiff(s): Longitude Licensing Limited and Marlin Semiconductor Limited.
• Defendant(s):
  • Western District of Texas (1:25-cv-00215): Apple, Broadcom, and Qualcomm.
  • Eastern District of Texas (2:25-cv-00171): Lenovo (Motorola Mobile Communication), OnePlus, and TSMC.

• Filing Date: These complaints were filed in early 2025, prior to the ITC complaint (e.g., "Roughly one week after suing Apple... in a Western District of Texas complaint... IPValue... subsidiaries... filed a complaint before the International Trade Commission (ITC)").
• Outcome or Current Status: These are companion cases to the ITC investigation (337-TA-1443) and are ongoing.

It's important to note that Marlin Semiconductor Limited acquired US8076194 from United Microelectronics Corporation (UMC) in a June 2021 assignment. Therefore, any litigation initiated by Marlin Semiconductor Limited involving this patent would be after this assignment date. Previous litigation involving UMC, such as the trade secret case with Micron Technology, did not directly involve patent 8076194.
