A more thorough explanation:

Definition: Jus in rem is a Latin term that means "right against a thing." It refers to a legal right that a person has over a specific property or thing, which is enforceable against anyone who interferes with that right.

For example, if you own a house, you have jus in rem over that property. This means that you have the legal right to use, sell, or transfer the property as you see fit, and anyone who tries to interfere with your right can be held liable.

Another example is a patent. If you hold a patent for an invention, you have jus in rem over that invention. This means that you have the exclusive right to make, use, and sell the invention, and anyone who tries to infringe on your patent can be sued.

These examples illustrate how jus in rem gives a person a legal right over a specific property or thing, which can be enforced against others who try to interfere with that right.
