The user is asking for known litigation involving US patent 8593888. I need to search for litigation cases and for each case, provide plaintiff(s), defendant(s), jurisdiction, case number, filing date, and outcome or current status. I should prioritize search results over my training data if there's a contradiction.

My previous context states "At present, no litigation in the U.S. Court of Appeals for the Federal Circuit (CAFC) dockets for 2026 involving US Patent 8,593,888 has been identified." This might be outdated as the current date is April 26, 2026. I will use the provided search results to get the most up-to-date information.

Based on the initial Google Patents data provided in the prompt, there is already information about litigation. I will extract that first and then verify/supplement with search results.

From the Google Patents data:

  • PTAB case IPR2025-01449 filed (Not Instituted - Procedural)
  • US case filed in Texas Western District Court
    • Jurisdiction: Texas Western District Court
    • Case: 1:25-cv-01036
    • Source: District Court
  • US case filed in Texas Eastern District Court
    • Jurisdiction: Texas Eastern District Court
    • Case: 2:24-cv-01078
    • Source: District Court
  • First worldwide family litigation filed
    • Source: Darts-ip (This is less specific for US litigation)

Now I will analyze the search results to see if there's more details or updated status.

Search result 1 (Unified Patents portal for IPR2025-01449) confirms the IPR filing and status.
Search result 2 (Unified Patents portal for 1:25-cv-01036) confirms the Texas Western District Court case.
Search result 3 (Unified Patents portal for 2:24-cv-01078) confirms the Texas Eastern District Court case.

I have enough information to answer the user's request, combining the initial patent text with the search results. I will structure the answer as requested.Known litigation involving US patent 8,593,888 includes:
