Apple Watch Series: A doctor took legal action against it

A patent violation lawsuit was filed by a cardiologist over the feature of a lifesaving Apple Watch, which has the potential of noticing if the wearer has an irregular heartbeat.

Dr. Joseph Wiesel, a teacher at the New York University School of Medicine, was once given a patent on March 28, 2006, for noticing atrial fibrillation (irregular heartbeat), that may cause blood clots, a stroke, or a heart failure. His technique uses photoplethysmography, a procedure used by the Apple Watch with its green light and related sensors.

According to Dr. Wiesel, he informs Apple about the existence of his patent on September 20, 2017, 2 days before the release of Apple Watch Series 3. The lawsuit declares that Apple declined the negotiations in good faith with Dr. Wiesel even after the “detailed claim charts” provided by him, which showed how the Apple Watch infringed on his patent.

He also declares that his patent. described as “pioneering steps in atrial fibrillation detection,” is a “severe part” of the wearable device, as the ability to detect heartbeats is one of the features of Apple’s marketing enterprise for the product.

In the lawsuit, Dr. Wiesel asked royalties, legal fees and recovery of past damages, as Apple’s claimed patent infringement was explained as “willful, intentional, and deliberate.”

Apple Watch Series 4 is where the electrocardiogram functionality first appeared. It uses the electrodes at the back of the wearable watches and gets activated by using the finger of the user to touch Digital Crown for 30 seconds.

“The Apple Watch Series 4 was identical to single-lead ECG, which doesn’t make it as correct as some other ECG device, but useful enough in identifying possible problems and encouraging its wearer to visit the hospital for a more thorough check-up,” said Dr. Nicholas Tullo, a cardiac electrophysiologist, to Digital Trends.
