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.
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.
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.
The most logical and simple way is to directly approach the Patent Office(s) in different countries and simultaneously file an application there. However, the process can be quite expensive and cumbersome as the inventor would have to simultaneously keep track of all the applications.
Similarly, a foreign patent or publication would also serve as prior art against a subsequently filed US application. Prior art, therefore, has a worldwide effect in blocking future applicants from patenting the same thing.
By filing one patent application with the U.S. Patent and Trademark Office (USPTO), U.S. applicants can concurrently seek protection in up to 143 countries. Learn more about filing an international patent application under the PCT.
Submit the application to the World Intellectual Property Organization (WIPO) or a national patent office. Your invention is then provisionally protected in all contracting states of the Patent Cooperation Treaty (PCT). The WIPO carries out a search on the state of the art (also known as the prior art).
Patents are country-specific and are rights limited to the borders of the issuing country.
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.
