Known litigation involving US patent 7548592 is not directly detailed in the provided search results. The prior "Patent summary" section notes that the patent information page indicates "Family has litigation" with cases filed in Texas District Courts and a "First worldwide family litigation filed" dating back to 2004. However, a specific search for US7548592 in litigation databases like Unified Patents, CAFC, or PACER, as conducted, did not immediately return direct case listings for this precise patent number with the requested details (plaintiffs, defendants, jurisdiction, case number, filing date, and outcome/status).
One search result referenced an IPR case (IPR2021-01260) involving Unified Patents, LLC as petitioner and AUTHWALLET LLC as patent owner, but this case was for Patent No. 9,292,852, not US7548592. Other search results provided general information about Unified Patents or their search portal, without specific litigation data for US7548592.
Therefore, based on the current search, specific details of litigation (plaintiffs, defendants, case number, filing date, and outcome/status) for US patent 7548592 are not available.
