Definition: bằng sáng chế có hiệu lực pháp lý.
A more thorough explanation: A legally effective patent refers to a patent that has been granted by a government authority, such as the United States Patent and Trademark Office (USPTO), and is legally enforceable. This means that the patent holder has exclusive rights to the invention covered by the patent, and can take legal action against others who infringe on those rights. In order for a patent to be legally effective, it must meet all the requirements set forth by the relevant patent laws and regulations, including novelty, non-obviousness, and utility.
Example: The legally effective patent was granted by the United States Patent and Trademark Office after a thorough review of the application.
