priority of invention

Priority of invention is a legal principle that determines who first created a particular invention or discovery. When two people claim to have invented the same thing independently, the one who can prove they invented it first generally has the rights to patent it. This concept helps establish the original inventor’s rights and prevents others from claiming the invention later. It's like a “first to file” or “first to invent” rule used in patent law to decide who has the legal claim to an invention.
