thought
The user is asking for known litigation involving US patent 7061859.
I need to search for litigation cases related to this specific patent number.
I will use the provided search sites like Unified Patents and consider PACER as a good source.
For each case found, I need to extract the plaintiff(s), defendant(s), jurisdiction, case number, filing date, and outcome or current status.
If no litigation is found, I should explicitly state that.

Based on the initial patent text provided, there are already some indications of litigation:

I will use the search results to confirm and expand upon this information, and look for any other cases.

My current date is 2026-05-16. The user asked for "Current Date: April 26, 2026". I will use today's date (2026-05-16) for my analysis, but acknowledge the user's specified date if there's any discrepancy in information availability.

Let's break down the search results for US patent 7061859 litigation.

From the patent text provided:

  1. PTAB case IPR2025-01088: "PTAB case IPR2025-01088 filed (Not Instituted - Procedural)".

    • Jurisdiction: PTAB (Patent Trial and Appeal Board)
    • Case number: IPR2025-01088
    • Filing date: The Google Patents page shows "2025-07-22" as the "Aia trial proceeding filed before the patent and appeal board: inter partes review" date for this IPR, and also "Effective date: 20250602". The IPR filing date seems to be 2025-07-22 according to the Legal Events section.
    • Petitioner: "Unified Patents PTAB Data" by Unified Patents is listed as the source, but it doesn't explicitly name the petitioner. However, the legal events section shows "Opponent name: CISCO SYSTEMS, INC.". So Cisco Systems, Inc. is likely the petitioner.
    • Outcome/Status: "Not Instituted - Procedural".

  2. US case filed in Texas Eastern District Court: "US case filed in Texas Eastern District Court litigation (https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/2%3A24-cv-01074)".

    • Jurisdiction: Texas Eastern District Court
    • Case number: 2:24-cv-01074
    • Filing date: Not explicitly stated in the provided text, but the case number 2:24-cv-01074 suggests it was filed in 2024. I need to get the exact filing date from the search results.
    • Plaintiff(s)/Defendant(s): Not explicitly stated in the provided text. I need to get this from the search results.
    • Outcome/Status: "Source: District Court". I need to find the current status.

I will now execute the search queries to gather more specific details and look for additional cases.

Search Result 1: "US7061859B2 - Fast protection in ring topologies - Google Patents"
This is the patent document itself, which I already have. It confirms the PTAB and Texas Eastern District Court cases mentioned above.

  • PTAB case IPR2025-01088: "PTAB case IPR2025-01088 filed (Not Instituted - Procedural)". Petitioner: "Unified Patents PTAB Data". The legal events section notes "Opponent name: CISCO SYSTEMS, INC.". Filing date for IPR is 2025-07-22, with an effective date of 2025-06-02.
  • US case filed in Texas Eastern District Court: "US case filed in Texas Eastern District Court litigation". Link provided is to Unified Patents: "https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/2%3A24-cv-01074".

Search Result 2: "Quicker Connections LLC v. Cisco Systems, Inc. (2:24-cv-01074) - Unified Patents"
This result directly addresses the Texas Eastern District Court case.

  • Plaintiff: Quicker Connections LLC
  • Defendant: Cisco Systems, Inc.
  • Jurisdiction: E.D. Texas
  • Case number: 2:24-cv-01074
  • Filing date: 2024-12-09
  • Current status: Active

Search Result 3: "IPR2025-01088 - Unified Patents"
This result directly addresses the PTAB case.

  • Patent Owner: Quicker Connections LLC
  • Case number: IPR2025-01088
  • Filing Date: 2025-07-22
  • Status: Not Instituted - Procedural

The previous section of the patent summary correctly stated: "A search for US patent 7061859 within CAFC 2026 dockets did not yield specific case information for 2026." The current search results do not contradict this; they confirm the two cases at the District Court and PTAB levels, but don't show any CAFC dockets for 2026.
