from the article, Taction themselves agreed Apple's tech was different :
"Apple's Taptic Engine is fundamentally different from Taction's technology, which Taction's own testing of Apple's products confirmed during trial," Apple said in response
"Apple's Taptic Engine is fundamentally different from Taction's technology, which Taction's own testing of Apple's products confirmed during trial," Apple said in response
So the article doesn't explain why it was appealed, then found shady on appeal.
it's a weird article, worth reading.
Appeals said that was inappropriately based on narrowing the claim too far and excluding expert testimony.
Second time a jury heard the whole thing, and found Apple infringed.
Also, “The jury did not find the infringement willful. Apple said it will appeal.”
