If one would obtain a patent in the U.S, does it become international? No one else can use/build it without the inventor's permission? Globally In other words, when an inventor obtains a patent in a country(for example the U.S) will it secure the invention globally for the inventors alone?
Also, will a patent exclude a government(international/local) form using/developing the inventor's patent without their permission? And will the legal system support the inventor due to their patent's support?
