Patent translation involves converting patent documents from one language to another. It must accurately reflect the technical content, legal terms, and formatting in the target language. Patent documents often include complex technical terms, legal definitions, and specific formatting rules. Therefore, the translation must ensure language accuracy, technical correctness, and legal compliance.
