Apple appeals record $5.7B Taction patent verdict

Apple has appealed the $5.7 billion patent verdict won by Taction Technology, arguing the jury calculated damages "based on guesswork" and that its findings are contradictory. Apple wants the court to rule it doesn't infringe and that the claims are invalid, or to order a new trial.

• The $5.7B award set a patent-law record, exceeding the previous high by over $3 billion
• Taction accused Apple of copying the Apple Watch Taptic Engine and won the jury verdict in September
• Apple says the plaintiff's own tests showed its tech relies on undamped resonance, not damped output
• Apple asks the court to invalidate the claims or order a new trial on infringement and damages
