How many years is an exterior patent valid?

Appearance patent refers to the patent protection of the design of a product, which mainly protects the appearance and design of the product, rather than the function or principle of the product. The validity period of appearance patents varies from region to region. Generally speaking, the validity period of appearance patents in most countries ranges from 15 to 25 years. The following will introduce the relevant contents of the validity period of appearance patents.

First of all, the validity period of appearance patents varies according to the laws and regulations of different places. In the United States, the validity period of appearance patents is 15 years, while in Europe, it is 25 years. In Asia, such as China, Japan and Korea, the validity period of appearance patents is usually about 15 to 20 years. Therefore, when applying for an appearance patent, the validity period should be determined according to the laws and regulations of the location.

Secondly, it is also necessary to pay attention to when the validity period of a patent for appearance begins to be calculated. Generally speaking, the validity period of a patent of appearance is calculated from the application date or the priority date. The filing date refers to the date on which the applicant submits the application for a patent of appearance to the Patent Office, while the priority date refers to the date on which an application for priority is filed under the Paris Convention or the Convention of the World Trade Organization. Therefore, when applying for a patent in appearance, it is necessary to pay attention to the determination of the filing date or the priority date in order to determine the starting date of the validity period of the patent in appearance.

In addition, after the expiration of the validity period of the appearance patent, the patentee may apply for renewal of the patent. Renewal of a patent means that before the expiration of an appearance patent, the patentee applies for an extension of the validity period of the appearance patent. Generally, the validity period of a renewed patent is a few years after the expiration of the original patent, and the specific renewal period varies according to the laws and regulations of different countries.

Generally speaking, the validity period of appearance patents varies from region to region, generally ranging from 15 to 25 years. When applying for a patent of appearance, it is necessary to determine its validity period according to the laws and regulations of the place where it is located, and pay attention to determine the date of application or the priority date, so as to determine the starting date of the validity period of the patent of appearance. In addition, the patentee can also extend the validity period of the appearance patent by applying for renewal of the patent.
