Patent protection is territorial, but worldwide novelty should be achieved to register a patent

A patent granted in one country does not automatically provide protection in other countries. In order to obtain patent protection in multiple countries, an inventor or applicant must file a patent application in each country where they seek protection.
Regarding worldwide novelty, an invention must be new and not disclosed to the public anywhere in the world before the filing of the patent application. This is known as the novelty requirement, which is one of the basic requirements for patentability.
