Novelty: One of the essential requirements for filing a patent in another country is that the invention must be novel, meaning it must be new and not previously disclosed. This requirement is necessary to prevent someone from filing a patent for something that already exists.
Is a patent valid in every country? Patents are territorial rights. In general, the exclusive rights are only applicable in the country or region in which a patent has been filed and granted, in ance with the law of that country or region.
If an earlier applicant obtains a patent first in their own country, can others subsequently patent the same invention in a different country? The simple answer “should” be no.
Patents are country-specific and are rights limited to the borders of the issuing country.
Since the rights granted by a U.S. patent extend only throughout the territory of the United States and have no effect in a foreign country, an inventor who wishes patent protection in other countries must apply for a patent in each of the other countries or in regional patent offices.

A U.S. patent holder can block importation and sale of an infringing machine, manufacture or composition of matter in the U.S. and can sue for damages. Suit can be brought against foreign companies in U.S. federal court, so long as the patent holder can serve the infringer.
Polaroid took Kodak to court in 1976, accusing it of infringing on 12 patents relating to instant photography. The pioneering instant camera and film company, now defunct, sought $12 billion in damages, a staggering sum even by today's standards.
