3. U.S. District Court, Eastern District of Texas Case

   • Plaintiff(s): Not explicitly detailed in search results.
   • Defendant(s): Not explicitly detailed in search results.
   • Jurisdiction: U.S. District Court for the Eastern District of Texas
   • Case Number: 2:26-cv-00150
   • Filing Date: Not explicitly stated in the provided snippets. The search results show other cases with a similar format (e.g., 1:26-cv-00150 in the District of Columbia with a Jan 20, 2026 filing date) but no direct match for 2:26-cv-00150 in E.D. Tex. involving US9651320B2.
   • Outcome/Current Status: Listed as litigation in the Google Patents source, implying active, but no further details on status from search.

4. Worldwide Family Litigation (Darts-ip)

   • The provided Darts-ip link points to the family of patents. While the Google Patents page mentions "First worldwide family litigation filed" with a link to Darts-ip for the family ID=47877767, it does not explicitly state that US9651320B2 itself is involved in this specific worldwide litigation beyond the US cases already identified. Since the request is for litigation involving "US patent 9651320", and no specific non-US litigation for this particular patent is detailed through the Darts-ip link in the patent information, I will only list the US-specific cases which are clearly associated with US9651320B2.The search results provided some details for the requested litigation cases.

For IPR2025-01288, the patent text provides the petitioner (Dell Technologies, Inc., and Dell, Inc.) and the outcome (Not Instituted - Procedural) and the filing date (2025-08-12). The patent owner is the current assignee, Cloud Byte LLC.

For case 2:24-cv-00637 in the Eastern District of Texas, search result explicitly states "Cloud Byte filed the above-captioned case against Defendants Dell Inc. and Dell Technologies Inc. on August 5, 2024, asserting seven patents against Dell; to-wit: U.S. Patent Nos. ... 9,651,320". It also mentions a "MEMORANDUM ORDER & OPINION" from January 29, 2026, granting a motion to dismiss defendants' counterclaims.

For case 2:26-cv-00150 in the Eastern District of Texas, the initial patent information lists it but the search results do not directly provide plaintiff, defendant, or filing date in relation to US9651320. Search result lists it as a Unified Patents litigation entry, but doesn't specify the parties for that specific entry in the snippet. Other search results for "2:26-cv-00150" are for different jurisdictions or different contexts. Without a direct link to the patent and parties in the provided search results, I cannot confidently provide those details for this specific case number.

Therefore, I have sufficient information for the IPR and the 2:24-cv-00637 case. For 2:26-cv-00150, I can only state the case number, jurisdiction, and that it is mentioned as litigation for the patent, but not the parties or filing date from the provided snippets. I will also note that the "First worldwide family litigation" mentioned in the patent text is not directly about US9651320B2, but the patent family, and no specific non-US litigation for this patent was found.Known litigation involving US patent 9651320 includes the following cases:
