San Diego jury orders Apple to pay $5.7B for Taptic Engine patent infringement

Key points

• A US federal jury in San Diego awarded Taction Technology more than $5.7 billion in damages against Apple for patent infringement.
• The case centers on two patents (U.S. Patent Nos. 10,659,885 and 10,820,117) covering vibration-based tactile transducers used in Apple’s Taptic Engine.
• The jury found that Apple infringed the patents but did not find the infringement to be willful, which may limit enhanced damages.
• Apple stated it strongly disagrees with the verdict and damages, calling them unsupported by facts, and announced plans to appeal.
• The lawsuit was filed in 2021, with a summary judgment for Apple in 2023 overturned by the Federal Circuit in August 2025, leading to the trial.

Background

This case has a complex procedural history. Taction Technology first sued Apple in 2021 in the US District Court for the Southern District of California. Apple initially won a summary judgment in 2023, but the US Court of Appeals for the Federal Circuit revived the case in August 2025, ruling that the district court had improperly excluded expert testimony and misinterpreted patent claims. The trial began on September 14, 2026, with jurors deliberating for parts of two days before returning the verdict on September 25. The Taptic Engine, which provides haptic feedback, debuted in the Apple Watch in 2014 and was later integrated into the iPhone 6s and subsequent models.

How outlets are covering it

All four sources agree on the core facts: the $5.7 billion award, the infringement finding, and Apple’s intent to appeal. CNBC and Bloomberg Law News emphasize the procedural history, noting the Federal Circuit’s role in reviving the case after Apple’s 2023 summary judgment win. Bloomberg Law News additionally highlights that Taction’s litigation was funded by entities linked to Burford Capital, a litigation finance company, which Apple had previously sought to expose. 9to5Mac and Law Commentary focus more on the technology at issue, describing the Taptic Engine’s function and Apple’s argument that its technology is fundamentally different from Taction’s patents. All sources note that the jury did not find the infringement willful, a detail that could impact potential enhanced damages under patent law.

Why it matters

The $5.7 billion verdict is one of the largest patent infringement awards in US history and could have significant implications for Apple’s future haptic technology development and licensing. The case also highlights the role of litigation finance in patent disputes, as Taction’s funding by entities linked to Burford Capital drew scrutiny. Apple’s appeal and the potential for enhanced damages if the infringement is later deemed willful could prolong the legal battle and influence how companies approach haptic technology patents in the future.

What to watch

Apple is expected to challenge the $5.7 billion damages award in post-trial proceedings before Judge Todd W. Robinson before pursuing its announced appeal. Any appeal involving patent issues would return the case to the Federal Circuit, the same court that revived the lawsuit in 2025. The outcome of the appeal could determine whether the damages are reduced or if the case proceeds to a retrial on certain issues.
