/juːˈnɪti ʌv ɪnˈvɛnʃən/ – Phrase
Definition: sự thống nhất của sáng chế.
A more thorough explanation: Unity of invention refers to a requirement in patent law that a patent application must relate to a single invention or a group of inventions that are so linked as to form a single general inventive concept. This requirement ensures that a patent application does not cover unrelated or disparate inventions, and helps to maintain the clarity and coherence of the patent system.
Example: The patent application was rejected by the patent office due to lack of unity of invention, as the claims encompassed multiple distinct inventions that were not sufficiently linked or related.
