Apple’s $5.7 billion Taptic Engine patent verdict may not be the end of the bill. Taction Technology has now asked the court for more money, including royalties on future iPhone and Apple Watch sales.
The new filing, reported by Reuters, seeks supplemental damages for sales made after the jury’s cutoff of March 2026. The company also wants interest on the award and ongoing royalties on products Apple has not sold yet. The jury found that the Taptic Engine, which generates the tapping and vibration feedback in iPhone and Apple Watch models, infringed two Taction patents.
Taction wants royalties on the iPhone 18 Pro and Apple Watch Ultra 4 through 2035
The jury’s award only counted Apple sales through March 2026. Taction now wants payment for the iPhone and Apple Watch sales that came after, since they were never part of the original calculation.
It also wants the court to extend the royalties to newer products that are close variants of the ones the jury found infringing. The filing names the iPhone 18 Pro, the iPhone 18 Pro Max and the Apple Watch Series 12 and Apple Watch Ultra 4.
Taction backs the request with Apple’s own argument from earlier litigation against Samsung, where Apple said royalties should also cover close variants of infringing products. Altogether, Taction is asking for four things:
- Supplemental damages for iPhone and Apple Watch sales after March 2026.
- Ongoing royalties on future sales through September 24, 2035, when the patents expire.
- Quarterly US sales reports from Apple, with royalties due within 30 days after each quarter ends.
- Prejudgment interest at 7% a year under California law, starting from April 2021, plus interest from final judgment until Apple pays.
Apple is still fighting to wipe out the original verdict
Apple has asked the judge to throw out the jury’s decision or order a new trial. It argues Taction gave the jury no real evidence to support the $5.7 billion figure, so the number amounts to guesswork. Apple has also said it will appeal.
Apple maintains that the Taptic Engine is fundamentally different from Taction’s technology and does not use the patented inventions. The jury disagreed, although it did not find that the infringement was wilful.
Taction first sued Apple in 2021 over patents covering tactile transducers. A federal judge ruled for Apple in 2023, but the Federal Circuit revived the case, and the jury verdict followed in September 2026. The judge has not yet entered the verdict as a final judgment, so the $5.7 billion award and every new demand remain undecided.
