Generic drugs are drugs that are not protected by patents. A drug with an expired patent means that the patent of this drug has passed the protection period, which is equivalent to no patent. During the patent period, most of these expired patented drugs have been well marketed by patent-owned companies. After the protection period, it can be copied, that is, generic drugs. Some generic drugs are the drugs of the other party within the protection period, but it is also allowed to add crystal water or change salt to the drugs to imitate them. Most of our country is generic drugs.
For example, common cold medicines and aspirin used to be patented medicines, but now they are non-patented medicines, which are not protected by patent rights and can be produced by any enterprise.
