In the US, unless you are signing a contract of some sort, then a sale is a sale. Any physical object that you simply buy at the store is yours, full stop.<p>I don&#x27;t understand the comment that you make about not owning the batteries in an electric car. If you own the electric car, then you own the batteries, that&#x27;s not in question.<p>However, manufacturers often put measures into place that make ownership less useful:<p>-- They might load software into the device that makes it respond to their control, and limits your ability to use the object<p>-- They might restrict availability of manuals, repair parts and other information to incentivize you to use their service facilities<p>However, I would argue that these are not the same as infringing on your ownership.
