In early December 2020, Patently Apple posted a report titled "Apple has been sued by EKG Device Maker AliveCor for Patent Infringement." In late June 2022 we posted another report titled "An Initial Determination from an International Trade Commission Judge Finds that Apple Infringed AliveCor’s Patented ECG related Technology." Late yesterday, Apple filed a 4-count counter patent infringement lawsuit against AliveCor in California.
