The generic name of a drug is a name registered and approved for use by the State Food and Drug Administration.

Drug trade names and brand names are both trademarks and need to be applied for at the Trademark Office.

To put it bluntly, the common name of the medicine bottle is the true identity of the medicine, while the trade name and trademark of the medicine are just a symbol or substitute name for the medicine.

For drugs with the same ingredients and dosage forms produced by different manufacturers, the common names are the same, but the trade names and trademarks of the drugs must be different.

For example: Cold medicine with the same ingredients - Compound Paracetamol Tablets is the generic name of the drug, and words like "**Kang, **Tai, **Ning", etc. are all trade names and trademarks.
