The user is asking for known litigation involving US patent 12160681. I need to search for litigation records on relevant platforms like Unified Patents, CAFC, and PACER.

Based on the provided patent text, I already see some litigation information listed under "Legal status" section on Google Patents. I should prioritize these as they are directly linked to the patent record itself.

The "Legal status" section mentions:

• "Family has litigation" with a link to Darts-ip.
• "US case filed in Texas Eastern District Court" with a link to Unified Patents.
• "PTAB case IPR2025-01310 filed (Pending - Instituted)" with a link to Unified Patents.

I will extract the details for these cases.

Let's break down the information needed for each case:

• plaintiff(s)
• defendant(s)
• jurisdiction
• case number
• filing date
• outcome or current status

For the "US case filed in Texas Eastern District Court":

• Jurisdiction: Texas Eastern District Court
• Case number: 5:25-cv-00052
• Source: District Court
• Status: No explicit outcome mentioned, but it's a "US case filed". I'll check the Unified Patents link.

For the "PTAB case IPR2025-01310":

• Jurisdiction: PTAB
• Case number: IPR2025-01310
• Status: Pending - Instituted
• Petitioner: The source mentions "Petitioner:" but does not list a name. I'll check the Unified Patents link.

The Darts-ip link mentions "First worldwide family litigation filed", but doesn't immediately provide specific US case details. The request is specifically for US patent 12160681, not the entire family. I will focus on the explicit US cases mentioned.

I will use the provided snippets from the initial search to populate the details.

From the Google Patents page for US12160681B2:

• "Family has litigation" - "First worldwide family litigation filed litigation Critical https://patents.darts-ip.com/?family=[42710753](/patent/42710753)&utm_source=google_patent&utm_medium=platform_link&utm_campaign=public_patent_search&patent=[US12160681](/patent/US12160681)(B2)"
• "US case filed in Texas Eastern District Court litigation https://portal.unifiedpatents.com/litigation/Texas%20Eastern%20District%20Court/case/5%3A25-cv-00052 Source: District Court Jurisdiction: Texas Eastern District Court"
• "PTAB case IPR2025-01310 filed (Pending - Instituted) litigation https://portal.unifiedpatents.com/ptab/case/IPR2025-01310 Petitioner:"

I need to access the linked Unified Patents URLs to get more detailed information, specifically the filing dates and to identify plaintiffs/defendants where not explicitly stated in the Google Patents overview.

However, the operating rules state: "When live web search results contradict your training data, prefer the search results." and "Cite specific claims, prior-art references, and URLs when grounding statements."
I don't have direct access to click these links and browse the external sites in this environment. I must rely only on the text provided in the prompt and the initial Google Search results.

Let's re-evaluate the provided text for the requested information for each case without clicking the links.

Case 1: US case filed in Texas Eastern District Court

• Jurisdiction: Texas Eastern District Court
• Case number: 5:25-cv-00052
• Filing date: The provided text doesn't explicitly state the filing date. It just says "US case filed".
• Plaintiff(s): Not explicitly mentioned in the snippet.
• Defendant(s): Not explicitly mentioned in the snippet.
• Outcome or current status: The snippet just says "US case filed".

Case 2: PTAB case IPR2025-01310

• Jurisdiction: PTAB
• Case number: IPR2025-01310
• Filing date: The snippet says "IPR2025-01310 filed". It doesn't give a specific date, but the "2025" in IPR2025-01310 suggests it was filed in 2025.
• Plaintiff(s): "Petitioner:" is mentioned, but no name is provided.
• Defendant(s): Not explicitly mentioned, but in an IPR, the patent owner (Maxell Ltd.) would be the patentee.
• Outcome or current status: Pending - Instituted

Since I cannot click on the URLs, I cannot retrieve more specific details like the exact filing date for the District Court case or the petitioner's name for the PTAB case. I will explicitly state what information is missing.

I need to perform a general Google search to see if "US patent 12160681 litigation" can yield more direct text snippets for filing dates or parties without requiring me to "click" links. The previous search already included this.

Let's analyze the search results again for any new information that directly answers the missing parts without requiring me to interpret links or visit external sites.

The initial search results provided within the prompt already list the legal status information. I need to carefully extract only the information directly present in these snippets.

• "US case filed in Texas Eastern District Court litigation" provides the jurisdiction and case number. It also states "Source: District Court".
• "PTAB case IPR2025-01310 filed (Pending - Instituted) litigation" provides jurisdiction, case number, and status. It mentions "Petitioner:" but without a name.

The full patent text also includes a timeline of legal events. Let's re-examine that section as it might provide filing dates.
Under "Legal status (The legal status is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.)":

• There are entries like "2023-02-23 Application filed by Maxell Ltd" which is the filing date for the patent itself, not the litigation.
• There are no specific "litigation filed" dates listed in the main timeline, other than the aggregated status under "Family has litigation" and the two specific cases.

Given the constraints, I will report the information that is explicitly available in the provided text.Known litigation involving US patent 12160681 is as follows:
