Joseph Wiesel, a clinical assistant professor in cardiology at NYU School of Medicine, has filed suit against Apple (2:19-cv-07261), alleging that the tech giant has infringed a patent—generally related to detecting atrial fibrillation by monitoring a pulse—on which Wiesel is the sole named inventor. The accused products are various versions of the Apple Watch, Series 3 and 4 through purported inclusion of an irregular pulse notification feature, and earlier versions through the alleged provision of a software upgrade to add “irregular pulse notifications resulting from checking a pulse rhythm”.
