Duration of protection of design patents under the patent law
According to the Patent Law, a design patent refers to the shape, texture, pattern or combination thereof, as well as the color or combination thereof, of a product, but does not include the novelty of the technical solution. The term of protection of a design patent refers to the period of time during which the patentee enjoys exclusive rights over the product to which the design patent applies. In most countries, the term of protection of a design patent usually ranges from 15 to 25 years, depending on the local law.
The term of protection of a design patent begins on the date of filing or the priority date and continues for a fixed period of time. During this period, the patentee may prevent others from making, using, selling or importing products identical or similar to the patented design without a license. The purpose of such a protection period is to encourage innovation, protect the legitimate rights and interests of designers and enterprises, and promote fair and orderly market competition.
However, it should be noted that the term of protection of a design patent is not permanent. Once the term of protection expires, the patented design enters the public domain and anyone is free to use the design without paying any fees to the patentee. This means that other businesses can start producing and selling products that are identical or similar to the design without fear of patent infringement. Therefore, for the patentee, after the expiration of the protection period, he needs to look for other competitive advantages, such as brand image, product quality, market positioning, etc. to compete in order to maintain his market position.
In addition, the duration of protection for design patents is also affected by the patent legal system. Some countries may allow an extension of the term of protection to make up for the loss of time in the application and examination process, so as to extend the term of protection of the patent. In addition, some countries may have established special provisions on the term of protection of patents, such as adjusting the term of protection for certain specific industries or technological fields, so as to better adapt to market demands and industrial development.
In conclusion, the term of protection of a design patent is an important part of the patent legal system, which not only concerns the interests of the patentee, but also affects the pattern of market competition and the impetus of product innovation. Therefore, when applying for a design patent, the applicant needs to carefully understand the provisions of the local patent law, reasonably arrange the application and protection strategy to maximize the protection of his own rights and interests, and promptly adjust the competition strategy after the expiration of the protection period to cope with the market changes.
