It is important to note that the patent document also lists a US case 2:23-cv-00165 filed in Texas Eastern District Court. However, the provided search results from November 2025 pertaining to IPR2025-01412 and IPR2025-01396, which discuss litigation involving the '512 patent, do not mention 2:23-cv-00165 as an active case asserting the '512 patent alongside the 2:25-cv cases. The search results primarily focus on the 2:25-cv-00358 and 2:25-cv-00440 cases for the '512 patent, indicating these are the primary ongoing litigations. The details for 2:23-cv-00165, such as plaintiff, defendant, and outcome, are not explicitly provided in the patent text or further elaborated in the search results in connection with US8319512. Therefore, while acknowledged as having been filed, specific actionable details about its current relevance to US8319512 are not available within the provided authoritative text.
