Patent protection period
During the period of drug patent protection
Generic drug companies will not honestly wait for your original drug patent to expire before listing. They will try their best to get the approval of listing in advance and pass the patent challenge of section IV in the United States. This is also allowed by laws and regulations.
Generally speaking, an original drug can not be challenged except for the compound patent (expired first), and other patents including crystal form, preparation and application may be challenged. Once the challenge is successful, the patent will be terminated, and generic drugs can be listed in advance to obtain huge benefits.
The above is how to inquire about the specific method of drug patent protection period. Patent data is very important and is one of the core points of a pharmaceutical company. If generic drugs are not listed, the price of the original drug will gradually decline, which will lead to the withdrawal of the original drug from the market and basically leave it to generic drugs. After all, the logic of making money by original pharmaceutical companies is different from that of generic drugs. It is the original pharmaceutical company that obtains excess profits through the protection period, so it is necessary to thoroughly understand the patent data of drugs at this point.
