The examination and approval institutions are different, and the contents are different. The difference between drug patent approval and clinical review is that the approval agencies are different. China National Intellectual Property Administration is responsible for drug patent examination and approval, and the State Administration of Pharmaceutical Products is responsible for clinical examination. The content of examination and approval is different. The examination and approval of drug patents mainly examines drug-related patents, including patent application, authorization and invalidation. Clinical evaluation is to review the clinical trial data of drugs, including the safety, effectiveness and quality of drugs.
In the process of drug development and marketing, pharmaceutical companies need to pay attention to both drug patent approval and clinical evaluation. Clinical trials are needed to prove the safety and effectiveness of drugs before they are put on the market.
