What is the difference between a U.S. patent and a foreign patent?

A patent is a set of exclusive rights granted by a governing body to an inventor for a specific period of time in return for public disclosure of the invention. A U.S. patent grants a creator the right to stop others from making, using, or selling their invention in the United States. A foreign patent, on the other hand, grants the creator similar protection in other countries or regions outside of the United States. Patents are regulated by the United States Patent and Trademark Office (USPTO), which is the federal agency responsible for granting patents in the United States. A U.S. patent is granted based on the USPTO’s assessment of an invention’s novelty and non-obviousness, meaning the invention is different from anything else already developed, and must not be an obvious variation of existing technology. Foreign patents, however, are regulated by the individual governments of each foreign country. Each country has its own set of laws and regulations regarding patents, so it is important to research the specific laws of each country where you wish to pursue a foreign patent. Additionally, the international IP systems of certain countries may provide additional protection, like the European Union’s European Patent Convention. In summary, U.S. patents protect creators in the United States, while foreign patents protect creators in other jurisdictions outside of the United States. U.S. patents are granted by the USPTO based on novelty and non-obviousness, whereas foreign patents are granted by the individual governments of each country, with each country having their own set of laws and regulations.
