AT&T (T), Verizon (VZ), T-Mobile (TMUS) have defeated claims made by Taiwan's ASUS.

Patent and licensing disputes between handset and component makers and the large US carriers have been a recurring feature of the sector, and outcomes at this stage of a claim have historically been non-events for carrier equity, since any liability at stake is typically small relative to these balance sheets and the revenue line is untouched either way. The more consequential strand in past episodes of this kind has been the counterparty side: for a smaller claimant, a defeated claim closes off a licensing income avenue and can foreshadow renewed assertions through different venues or jurisdictions, a pattern seen repeatedly in telecoms and standards-essential patent fights. The distinction worth drawing is between a final judgment and an interim or procedural ruling, since the former ends the matter while the latter usually just shifts the battleground. Follow-ons in comparable cases have been appeals, refilings in plaintiff-friendlier forums, or a quiet settlement that converts the dispute into a royalty arrangement. Absent a damages figure in the headline, the read-through for the carriers is negligible; the signal is about the claimant's litigation posture.
