AliveCor wants to block the importation of all the Apple Watches in U.S. – and claims the tech giant is infringing on three counts of ECG patents. The Mountain View, CA-based company filed the complaint with the U.S. International Trade Commission.

AliveCor has developed the KardiaMobile device that can provide instant detection of Atrial Fibrillation, Bradycardia, Tachycardia, Sinus Rhythm with Supraventricular Ectopy, Sinus Rhythm with Premature Ventricular Contractions, Sinus Rhythm with Wide QRS and Normal Heart Rhythm. The technology is FDA-cleared.

In December 2020, AliveCor filed a federal lawsuit alleging Apple infringement of the same patents. AliveCor said in a release that filing in the ITC "is one step, among others, that it is taking to obtain relief for Apple's intentional copying of AliveCor's patented technology—including the ability to take an ECG reading on the Apple Watch, and to perform heartrate analysis—as well as Apple's efforts to eliminate AliveCor as competition in the heartrate analysis market for the Apple Watch."

Apple won FDA clearance for its ECG app in September of 2018.
