What's the difference between drug patent number and registration certificate number?

That is, the drug has applied for a patent. After applying for a patent, each patent has a code name, called the patent number. Patents are divided into invention patents, utility model patents and appearance patents, and their patent numbers are also different.

The registration number is also the approval number of imported drugs. The domestic drug approval number starts with the word "Zhunzun Zun", and H/Z/S is divided into chemical drugs, Chinese patent medicines and biological products. National medicine Zhunzun J refers to imported sub-package varieties, which are different from pure imported varieties.
