The user is asking for known litigation involving US patent 11406402. I need to find the plaintiff(s), defendant(s), jurisdiction, case number, filing date, and outcome/current status for each case.

I have already identified two cases from the provided patent text:

  1. PTAB case IPR2024-01261
  2. US case filed in Court of Appeals for the Federal Circuit (case number 26-1719)

I will use the google_search tool to get more details about these cases, specifically focusing on the plaintiff(s), defendant(s), filing date, and current status/outcome.

Let's break down the search queries:

  • "US patent 11406402 litigation": This is a general query to find any additional litigation.
  • "IPR2024-01261 status": This will specifically target the PTAB case to get details like petitioner (plaintiff), patent owner (defendant), filing date, and outcome. The patent text already states "Final Written Decision" for this, but I'll check for more details.
  • "26-1719 Court of Appeals for the Federal Circuit status": This will target the CAFC case to get details like parties, filing date, and current status.
  • "Rapidpulse Inc patent litigation": This might provide context about the assignee's general litigation activity, which could be helpful if the specific patent number searches don't yield all the party names. However, the prompt specifically asks for litigation involving US patent 11406402, so I'll prioritize specific patent searches first.

Based on the prompt, I should prioritize the portal.unifiedpatents.com and patents.darts-ip.com links that were provided in the initial patent text, as well as general Google searches.
