Known Litigation for U.S. Patent 9,602,649
As of April 30, 2026, U.S. Patent 9,602,649 is asserted in one known litigation case. The information provided in the patent's file history on Google Patents, which links to the Unified Patents portal, appears to contain a clerical error in the case number.
The provided patent information contains a link to a case listed as 1:26-cv-00316 in the Western District of Texas. However, searches for this specific case number in various district courts reveal unrelated matters, such as immigration cases in the Texas Southern and New Hampshire District Courts, and other civil suits in the North Carolina Middle and New York Southern District Courts. A case with a similar number, 2:26-cv-00316, is an unrelated patent infringement suit in the Texas Eastern District Court.
Further investigation into litigation by the patent's current owner, K. Mizra LLC, shows they are an active plaintiff in patent disputes, often against major telecommunications companies. While these specific cases do not involve the '649 patent, they establish a pattern of litigation activity.
Given that the Unified Patents portal and the Google Patents entry both flag this patent as having litigation, it is highly probable that a case exists but is listed with a slightly incorrect case number in the available records. The most likely scenario is a minor typographical error in the docket number. Without a corrected case number, further details about the specific defendant, filing date, and status of the litigation concerning U.S. Patent 9,602,649 cannot be definitively ascertained at this time.
