Apple asks judge to overturn $5.7 billion Taction patent verdict

Apple is asking a federal judge to overturn a $5.7 billion verdict in a patent case brought by Taction Technology.

The case concerns two Taction patents for technology that creates haptic feedback, or vibrations, in devices such as the Apple Watch and iPhone.

A jury found that Apple infringed the patents, but not willfully, and awarded Taction $5.7 billion.

Apple says the damages figure was based on guesswork because Taction did not provide evidence showing what the patented technology was worth.

Apple also disputes infringement, arguing that its Taptic Engine works differently and that Taction’s expert used a flawed test.

Apple wants the verdict thrown out, and says the patent claims should also be found invalid; alternatively, it wants a new trial.

The judge has not yet ruled on Apple’s request.
