On March 7, 2025, a federal court affirmed a ruling in favor of Apple in its long-standing patent dispute with AliveCor, effectively preventing a potential import ban on the Apple Watch. The U.S. Court of Appeals for the Federal Circuit upheld the Patent Trial and Appeal Board's decision that AliveCor's three patents related to cardiac arrhythmia monitoring were unpatentable due to obviousness, as prior art would have motivated a person skilled in the art to utilize a machine learning algorithm for arrhythmia detection. This ruling allows Apple to continue importing its smartwatch without facing restrictions from AliveCor, which had sought to block imports based on its patent claims. The court's decision marks a significant victory for Apple in the ongoing legal battle with AliveCor, ensuring that the Apple Watch remains available in the U.S. market.
