The Google Patents page for US9093473 also lists a "US case filed in International Trade Commission" with case number "337-TA-3809". However, further research indicates that "3809" appears as an internal identifier associated with ITC Investigation 337-TA-1443 rather than a separate, distinct ITC investigation. Therefore, separate details for 337-TA-3809 as an independent litigation case are not provided.
