thought
The user is asking for known litigation involving US patent 9135456. I need to search for litigation records, specifically using Unified Patents, CAFC dockets, and PACER. I will list the plaintiff, defendant, jurisdiction, case number, filing date, and outcome/status for each case found. If no litigation is found, I will explicitly state that. I also need to make sure I don't auto-correct the patent number. I need to build on the previously generated sections and not repeat information.

Based on the previous sections, I already know about IPR2025-01202 and a US case filed in the Virginia Eastern District Court. I need to get the details for those and see if there are others.

From the provided text:

  • PTAB case IPR2025-01202 filed (Not Instituted - Procedural)
  • US case filed in Virginia Eastern District Court, case/1:25-cv-00514

I will prioritize search results if they contradict my training data.

Let's refine the search for litigation details to ensure I capture all required fields for the identified cases and any new ones.## Known Litigation Involving US Patent 9135456
