Definition: đối tượng sáng chế khó thấy.
A more thorough explanation: Non-obvious subject matter refers to an invention that would not have been obvious to a person having ordinary skill in the relevant field of technology at the time the invention was made. This is a key requirement for patentability, as inventions must be non-obvious in order to be granted a patent.
Example: The patent application was rejected because the invention did not involve non-obvious subject matter, as it was deemed to be a simple combination of existing technologies.
