The user is asking for known litigation involving US patent 8904194.
I need to search for patent litigation related to this specific patent number.
I will use the provided links and keywords to perform the search.
For each case found, I need to extract: plaintiff(s), defendant(s), jurisdiction, case number, filing date, and outcome or current status.
If no litigation is found, I will state that.

Based on the provided patent text, there are already some litigation details mentioned:

1. PTAB case IPR2025-01201: Status: (Not Instituted - Procedural). Link: https://portal.unifiedpatents.com/ptab/case/IPR2025-01201. Petitioner: Unified Patents PTAB Data.
2. US case filed in Virginia Eastern District Court: Status: litigation. Link: https://portal.unifiedpatents.com/litigation/Virginia%20Eastern%20District%20Court/case/1%3A25-cv-00514. Jurisdiction: Virginia Eastern District Court. Source: District Court.
3. First worldwide family litigation filed: Link: https://patents.darts-ip.com/?family=[35912925](/patent/35912925)&utm_source=google_patent&utm_medium=platform_link&utm_campaign=public_patent_search&patent=US8904194(B2).

I should use the search tool to verify the current status of these cases and see if any other litigation is found.

Let's refine the plan:

1. Start by explicitly mentioning the litigation found in the provided patent text.
2. Use the search tool to get the most up-to-date information on these specific cases (IPR2025-01201 and 1:25-cv-00514).
3. Also, perform a broader search for "US8904194 patent litigation" to catch any other cases not explicitly mentioned in the provided text.
4. Compile all found litigation details in the requested format.The initial search results from the google_search tool show information about the two cases already identified in the patent text: IPR2025-01201 and 1:25-cv-00514.

For IPR2025-01201:

• Unified Patents lists it as "Not Instituted - Procedural".
• The petitioner is "Unified Patents PTAB Data".
• The filing date is not explicitly stated in the snippet, but the case ID suggests 2025.
• The patent text states "PTAB case IPR2025-01201 filed (Not Instituted - Procedural)".

For 1:25-cv-00514:

• Unified Patents lists it as "litigation" in the "Virginia Eastern District Court".
• The case number is 1:25-cv-00514.
• The source is "District Court".
• The filing date is not explicitly stated in the snippet, but the case ID suggests 2025.
• The patent text states "US case filed in Virginia Eastern District Court litigation".

The "First worldwide family litigation filed" link from the patent text is a general link to Darts-ip and doesn't provide specific case details like plaintiff, defendant, case number, etc., without further navigation or parsing, which is beyond the scope of a direct search result snippet. I will focus on the more specific cases.

I have enough information to construct the response based on the patent document and the search results, as the search results confirm and slightly expand on the information given in the patent document itself. I will extract the details for each case as requested.As of April 26, 2026, the following litigation involving US patent 8904194 is known:

1. PTAB Case:

   • Case Number: IPR2025-01201
