Apple challenges $5.7B Taptic Engine patent verdict

Apple is asking a federal judge to overturn a $5.7 billion patent verdict brought by Taction Technology, arguing that the damages award was unsupported by the evidence and that the jury was left to speculate.¹

What Apple is challenging

A jury recently ordered Apple to pay $5.7 billion over two patents connected to the Taptic Engine used for haptic feedback in iPhones and Apple Watches. Apple had already said it disagreed with the verdict and planned to appeal.¹

In its new motion, Apple argues that Taction did not provide enough evidence to establish the value of its patented contribution or justify the damages figure. Apple says Taction asked the jury to award what it considered a reasonable royalty without giving it a reliable basis for calculating that amount.¹

Apple also points to the court’s treatment of Taction’s damages expert. According to Apple’s account of the filing, an earlier analysis was excluded because of flaws in the way royalties from a previous licensing agreement were calculated, and the expert was later barred from testifying.¹

Dispute over the technology and testing

The case also turns on how the patents’ vibration requirements should be measured. Apple argues that its Taptic Engine produces stronger vibrations at some frequencies rather than the consistent output described by the patents.

Apple further alleges that a Taction technical expert developed a test method specifically for the lawsuit. The company says that method examined Apple’s electronic control system rather than the hardware behaviour required by the patent claims.¹

Those are Apple’s arguments, not findings that have been accepted by the court. The judge must now decide whether to uphold the award, overturn the verdict or order a new trial covering infringement, patent validity and damages.¹

Why the $5.7 billion figure is still unsettled

Apple’s motion also raises questions about whether the figure on the verdict form reflected what the jury intended. The company says the judge had expressed uncertainty about the number before the award was announced.¹

The result is a case that remains in motion even after the headline-making verdict. A successful appeal could remove the damages award or send the dispute back for another trial; if Apple loses, the $5.7 billion judgment would remain a central part of the fight over the Taptic Engine patents.

Our opinion

This is a meaningful technology story because the dispute reaches beyond one damages number: it tests how courts value patents covering the physical behaviour of everyday device hardware. Apple’s filing is forceful, but it is still an advocate’s document rather than a judicial conclusion. The responsible read is that the verdict is being actively challenged, not that Apple has already disproved Taction’s case.

The next important milestone is the court’s response to the motion. Until then, the most eye-catching parts of Apple’s argument — including its description of the damages analysis as “guesswork” — should be treated as claims to be tested in the appeal process.¹
