Apple definitely did a lot of patent trolling but in this case their is no patent trolling involved. AliveCor did not come up with some vague patent without a legitimate product. They actually make and sell products that use this technology. Apple just stole it and that of course is illegal. There probably won’t be a ban, but apple can’t simply disable the ECG feature either as they advertised and sold the product with that feature in many markets, so this would expose them to huge class actions. I suspect apple will just have to open their wallet and pay substantial amounts to AliveCor for the past violations and possibly royalties for each new Apple Watch sold henceforth.
