Litigation summary

I have retrieved information about the litigation cases involving US11952167B2. I will now compile the requested details for each case.

Here's the breakdown of the litigation involving US patent 11952167:

Known Litigation Involving US Patent 11952167

1. PTAB Case: IPR2024-01401 (This appears to be the correct IPR associated with the patent, rather than IPR2025-01018 from the initial Google Patents listing, which was "Not Instituted - Procedural". The search results from CaseMine specifically mention IPR2024-01401 as involving the challenged patent along with 1:24-cv-04928 and 337-TA-1409.)

   • Plaintiff(s) / Petitioner: Klein Tools, Inc.
   • Defendant(s) / Patent Owner: Milwaukee Electric Tool Corporation & Keter Home and Garden Products, Ltd.
   • Jurisdiction: PTAB (Patent Trial and Appeal Board)
   • Case Number: IPR2024-01401
   • Filing Date: Not explicitly stated in the search results, but the "2024" in the case number suggests 2024.
   • Outcome or Current Status: Inter partes review was instituted on all challenged claims and on all grounds of unpatentability asserted for each claim, as the information presented showed a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims.

2. U.S. International Trade Commission (ITC) Investigation

   • Plaintiff(s) / Complainant(s): Milwaukee Electric Tool Corporation, Keter Home and Garden Products Ltd.
   • Defendant(s) / Respondent(s): Klein Tools, Inc. (implied by related district court cases)
   • Jurisdiction: U.S. International Trade Commission (ITC)
   • Case Number: 337-TA-3749 (Note: Search result mentions 337-TA-1409, but result specifically identifies 337-TA-3749 as involving "Certain Storage Containers and Toolboxes..." and references Milwaukee and Keter. The Google Patents litigation section also lists "337-TA-3749". I will use 337-TA-3749).
   • Filing Date: May 23, 2024
   • Outcome or Current Status: The complainants, Milwaukee and Keter, were terminated on June 11, 2024.

3. U.S. District Court, Northern District of Illinois Case 1

   • Plaintiff(s): Milwaukee Electric Tool Corporation et al. (including Keter Home and Garden Products Ltd.)
   • Defendant(s): Klein Tools, Inc.
   • Jurisdiction: Illinois Northern District Court
   • Case Number: 1:24-cv-04284
   • Filing Date: May 23, 2024
   • Outcome or Current Status: Voluntarily dismissed without prejudice by the plaintiffs on July 22, 2024, before the defendant filed an answer. This means the plaintiffs retain the right to re-file the claims later.

4. U.S. District Court, Northern District of Illinois Case 2

   • Plaintiff(s): Milwaukee Electric Tool Corp
   • Defendant(s): Klein Tools, Inc.
   • Jurisdiction: Illinois Northern District Court
   • Case Number: 1:24-cv-04928
   • Filing Date: June 13, 2024
   • Outcome or Current Status: This case was stayed pending a resolution of the USITC investigative proceedings (likely 337-TA-1409, as mentioned in, or 337-TA-3749). The reference to 337-TA-1409 in might be a typo or an older case number that has been updated to 337-TA-3749 in other sources. Given that the Google Patents entry and another Unified Patents link specify 337-TA-3749 for "Certain Storage Containers...", it's likely referring to the same subject matter.

5. First Worldwide Family Litigation

   • Jurisdiction: Global (Darts-ip provides data for worldwide litigation related to patent families)
   • Case Number: Not a single case number, but related to patent family ID 60202865.
   • Filing Date: Not specifically provided in the snippets.
   • Plaintiff(s): Not specifically provided in the snippets.
   • Defendant(s): Not specifically provided in the snippets.
   • Outcome or Current Status: The provided link goes to a Darts-ip page for the patent family, indicating that there is worldwide family litigation, but specific case details (plaintiffs, defendants, dates, outcomes) are not summarized in the provided search snippets.

Regarding IPR2025-01018, the original Google Patents text listed it as "Not Instituted - Procedural". However, search results for related cases, particularly, point to IPR2024-01401 as an instituted IPR involving the patent owner and petitioner (Klein Tools vs. Milwaukee Electric Tool Corp. & Keter Home and Garden Products, Ltd.). Therefore, I will include IPR2024-01401 as the active IPR. The IPR2025-01018 being "Not Instituted - Procedural" suggests it did not proceed.

I will construct the final response using the confirmed and detailed information.Known litigation involving US patent 11952167B2 includes the following cases:
