Apple is appealing a $5.7 billion jury verdict in a patent infringement case brought by Taction Technology involving the Taptic Engine used in iPhones and Apple Watches. Apple asks a federal judge to overturn the damages and related findings, arguing that the damages figure is not supported by reliable evidence.

According to filings reported by multiple outlets, Apple contends the jury’s calculation relied on “guesswork” and that the jury’s conclusions are internally inconsistent. The dispute centers on claims that Apple’s haptic feedback technology infringes two Taction patents. Taction sued Apple in 2021, and a jury found for Taction in September, determining Apple infringed but did not act willfully.

While both outlets describe Apple’s appeal and its challenge to the size and basis of the damages award, the specific emphasis differs: one outlet foregrounds the “guesswork” argument, while the other highlights alleged contradictory findings as another ground for throwing out the verdict.
