The user is asking for known litigation involving US patent 12167948.
I need to search for litigation related to this specific patent number on platforms that cover patent litigation.
The user provided a specific search site: https://portal.unifiedpatents.com/litigation/caselist.
I should also consider CAFC and PACER as good sources for litigation.
For each case, I need to provide: plaintiff(s), defendant(s), jurisdiction, case number, filing date, and outcome or current status.
If no litigation is found, I should state that.

My previous response about CAFC 2026 dockets stated "A search of the CAFC 2026 dockets did not reveal any specific litigation involving US patent 12167948." This is a specific type of search. I need to perform a broader search for all known litigation.

Based on the Google Patents page for US12167948B2, I see a "Legal status" section that mentions:

• "Family has litigation"
• "PTAB case PGR2025-00058 filed (Not Instituted - Procedural)" with a link: https://portal.unifiedpatents.com/ptab/case/PGR2025-00058
• "First worldwide family litigation filed" with a link: https://patents.darts-ip.com/?family=[73045920](/patent/73045920)&utm_source=google_patent&utm_medium=platform_link&utm_campaign=public_patent_search&patent=US12167948(B2)

I will use these links and the provided search queries to gather the requested information.

First, I will check the Unified Patents link for PGR2025-00058.
Then I will check the Darts-ip link for "First worldwide family litigation".
Finally, I will use the general search queries to see if anything else comes up.Known litigation involving US patent 12167948 includes a Patent Trial and Appeal Board (PTAB) case.

PTAB Case:

• Case Number: PGR2025-00058

• Jurisdiction: Patent Trial and Appeal Board (PTAB), United States Patent and Trademark Office (USPTO)
• Filing Date: The Google Patents record indicates the PTAB case was filed, though the exact filing date within 2025 is not directly stated in the snippet, only the case number PGR2025-00058.
• Outcome or Current Status: Not Instituted - Procedural. This means the PTAB decided not to proceed with the Post-Grant Review (PGR) for procedural reasons.

Further information from Darts-ip indicates "First worldwide family litigation filed" for family ID 73045920, which includes US12167948B2. However, the provided snippet does not detail the specific litigation related to US12167948B2 itself, nor does it list plaintiff(s), defendant(s), jurisdiction, case number, filing date, or outcome for this family litigation. Therefore, I cannot provide those details with high confidence for other potential litigation without direct results for US12167948.
