The search results from Unified Patents and PacerMonitor for the specific case numbers listed in the provided patent text revealed several litigation cases involving US Patent 9736618. I need to be careful to extract only the relevant cases and not other cases that happen to have similar case numbers but are not related to patent 9736618.

Based on the search results, here's the known litigation involving US patent 9736618:

  1. Piney Woods Mobility LLC v. T-Mobile USA, Inc.

    • Plaintiff(s): Piney Woods Mobility LLC
    • Defendant(s): T-Mobile USA, Inc.
    • Jurisdiction: Eastern District of Texas
    • Case Number: 2:26-cv-00123
    • Filing Date: February 13, 2026
    • Current Status: Complaint filed alleging infringement of six patents, including US Patent 9736618, related to two-way position information sharing technology. The case is active, with venue allegations that T-Mobile maintains regular and established places of business and has allegedly committed acts of infringement in the district. The complaint alleges T-Mobile had notice of the patent family since at least September 2010. Note: There were other cases with 2:26-cv-00123 in other districts, but the search results explicitly link this one to Piney Woods Mobility LLC and US Patent 9736618, and the jurisdiction matches what was initially indicated for a "Critical" litigation event for the patent.

  2. Piney Woods Mobility LLC v. [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)

    • Plaintiff(s): Piney Woods Mobility LLC
    • Defendant(s): [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)
    • Jurisdiction: Western District of Texas
    • Case Number: 7:26-cv-00068
    • Filing Date: February 26, 2026
    • Current Status: Case filed. Note: Another case with 7:26-cv-00068 was found in Georgia Middle District Court, but it is an immigration case and not related to the patent. The PacerMonitor result for Piney Woods Mobility LLC v. [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.) specifically links the case number to the patent assignee.

  3. Piney Woods Mobility LLC v. [Verizon Communications, Inc.](/litigations/by-defendant/Verizon%20Communications%2C%20Inc.) et al

    • Plaintiff(s): Piney Woods Mobility LLC
    • Defendant(s): [Verizon Communications, Inc.](/litigations/by-defendant/Verizon%20Communications%2C%20Inc.) et al
    • Jurisdiction: Eastern District of Texas
    • Case Number: 2:26-cv-00124
    • Filing Date: February 13, 2026
    • Current Status: Case filed. Note: Another case with 2:26-cv-00124 was found in Nevada District Court and Vermont District Court, but these are not related to the patent. The PacerMonitor result explicitly links this case to Piney Woods Mobility LLC and the patent assignee.

For the case numbers 2:26-cv-00121 and 2:26-cv-00122, the search results show multiple unrelated cases in different jurisdictions, and none of them explicitly link to US patent 9736618 or its assignee, Piney Woods Mobility LLC. Therefore, I cannot confidently list these as litigation involving the patent based on the provided search results.

The Darts-ip search for "First worldwide family litigation filed" was part of the original patent information and not directly a search result I initiated. The link provided in the original text goes to a general family litigation page on Darts-ip and doesn't provide specific case details without further navigation which is outside the scope of direct snippet extraction. I prioritize the specific case details found through the Unified Patents and PacerMonitor links directly related to the provided case numbers.
