'专利' (zhuānlì) literally combines '专' (zhuān), meaning 'special', 'exclusive', or 'dedicated', and '利' (lì), meaning 'benefit' or 'advantage'. Together, they form the legal concept of a 'patent' — an exclusive right granted by the government to an inventor, giving them sole authority to make, use, or sell an invention for a limited time. This term is used primarily in technological, pharmaceutical, and industrial contexts, where innovation and intellectual property protection are central.

In everyday Chinese, '专利' appears in news about new medical treatments, smartphone features, or green energy technologies. It’s also common in formal documents, corporate reports, and academic discussions. Unlike English, where 'patent' can occasionally function as a verb, '专利' is strictly a noun in Chinese and never used as a verb — you would say '申请专利' (apply for a patent), not '*专利这个技术'.
