Last month, Ironworks Patents LLC filed a new lawsuit against ASUSTek (2:19-cv-00016) in the Eastern District of Texas, asserting a familiar set of patents generally related to alerts, including tactile alerts, on a “mobile station”. That case followed on the heels of a settlement in the most recent previous case, filed against BLU Products in the Southern District of Florida; a dismissal in a set of district court and appellate actions against Apple; a settlement with TCL Communication; and an appeal from final judgment stemming from an unfavorable claim construction order in a Northern District of California case filed against Samsung. Ironworks has targeted features on smartphones and tablets for silencing “alert sounds” announcing, e.g., the receipt of a call, identifying in this most recent complaint ASUSTek’s ZenFone, PadFone, Memo Pad, VivoTab, ZenPad, and ROG phone devices.
