/ˌʌnˈɒbviəsnəs/ – noun
Definition: tính không hiển nhiên (của sáng chế).
A more thorough explanation: Unobviousness in legal English refers to the requirement that an invention must be unexpected or surprising to a person skilled in the art. It is a key criterion for patentability in many jurisdictions. This means that the invention cannot be merely an obvious extension of existing knowledge or technology.
Example: The unobviousness of the defendant’s actions made it difficult for the prosecution to prove intent in the case.
