/fɜrst tu faɪl rul/ – Phrase
Definition: quy tắc về quyền của người nộp đơn đầu tiên.
A more throughout explanation: The first-to-file rule is a legal principle in intellectual property law that grants priority to the first party to file a patent application for an invention, rather than the first party to invent the invention. This rule is used in many countries to determine who has the right to obtain a patent for a particular invention when multiple parties claim to have invented the same thing.
Example: Under the first-to-file rule, the patent will be granted to the inventor who first files a patent application for the invention, regardless of who actually invented it first.
