Timeliness of patent right?

The so-called temporality means that the exclusive right of the patentee to his invention and creation is only valid within the time stipulated by law. After the expiration of the time limit, the patentee no longer enjoys the exclusive right to manufacture, use, sell and import his invention and creation. In this way, inventions originally protected by law have become the public wealth of society, and any unit or individual can use them for free.

For the duration of the patent right, the patent laws of all countries clearly stipulate that the protection period of the invention patent right generally ranges from 10 to 20 years from the date of application; For utility model and design patents, most countries stipulate that the term of protection is 5 to 10 years, while the current patent law in China stipulates that the term of protection for invention patents, utility model patents and design patents is 20 years from the date of filing, 10 years and 10 years respectively.

Do not expire.
