The search results confirm the two litigation cases mentioned in the patent document and provide more details.

1. PTAB Case IPR2026-00234:

• Plaintiff(s): [[Samsung Electronics Co.](/litigations/by-defendant/Samsung%20Electronics%20Co.), Ltd.](/litigations/by-plaintiff/Samsung%20Electronics%20Co.%2C%20Ltd.) and Samsung Electronics America, Inc.
• Defendant(s): AQ Corporation
• Jurisdiction: Patent Trial and Appeal Board (PTAB)
• Case number: IPR2026-00234
• Filing date: January 26, 2026
• Outcome or current status: Pending

2. US District Court Case 2:25-cv-01012:
The initial search results from PacerMonitor for 2:25-cv-01012 show multiple cases with this number in different districts (Nevada, Washington Western, South Carolina) and with different parties. However, the patent document specifically states "US case filed in Texas Eastern District Court" for this case number. A more precise search result from Unified Patents confirms this specific case:

• Plaintiff(s): AQ Corporation
• Defendant(s): Samsung Electronics Co., Ltd. and Samsung Electronics America Inc.
• Jurisdiction: Eastern District of Texas
• Case number: 2:25-cv-01012
• Filing date: October 07, 2025
• Outcome or current status: Litigation (This is the status provided by the initial patent document and Unified Patents, implying it is ongoing).

Therefore, I have gathered the necessary information for both identified cases.

   • Outcome or Current Status: Litigation (ongoing)The user requested known litigation involving US patent 11728564, and provided specific sources to search and details to include for each case. The provided patent text already contained links to relevant litigation information. I used google_search to directly access and confirm details from those Unified Patents links.

Here's a breakdown of the information found and how it was used:

1. IPR2026-00234: The patent text directly linked to this PTAB case. The search result provided the petitioner (Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.), the patent owner (AQ Corporation), the jurisdiction (PTAB), the case number (IPR2026-00234), and the filing date (January 26, 2026). The status was confirmed as pending.

2. 2:25-cv-01012: The patent text mentioned a US case filed in the Texas Eastern District Court with this case number. Initial broader searches for this case number showed multiple cases in different jurisdictions. However, focusing on the specific jurisdiction mentioned in the patent (Texas Eastern District Court) and using the provided Unified Patents link for that specific case confirmed the relevant details. This result identified the plaintiff as AQ Corporation, the defendants as Samsung Electronics Co., Ltd. and Samsung Electronics America Inc., the jurisdiction as Eastern District of Texas, the case number as 2:25-cv-01012, and the filing date as October 07, 2025. The status is "litigation," indicating it is ongoing.
