How long is the protection period of American design patents? 1invention patents and plant patents filed on or after June 8, 995, the patent protection period is 20 years from the actual application date; The patent protection period of design is 14 years from the date of patent authorization. For an application for a patent for invention from May 29, 2000, the US Patent and Trademark Office will appropriately adjust the patent protection period according to the time delayed by the Patent and Trademark Office or the inventor.

In the design application of 1993, less than 10% obtained the patent, and the patent protection period reached 10 year. Most people apply for patents only to obtain patent certificates, so as to obtain professional titles, taxes and other benefits. Therefore, after obtaining the patent, we do not have the consciousness of applying the patent to industrial production, and many patents lose their patents because of the patentee. Some patentees only want to obtain short-term commercial benefits, and do not take it as their own brand products to occupy the market for a long time. For some powerful and strategic enterprises, it is hoped that their products can occupy the market for a long time and get effective legal protection. For them, the protection period of 10 years is relatively short. For designs, the protection period is different in different countries' laws: the protection period of Japanese designs is from the date of approval of registration 15 years; In Germany, the protection period is 20 years from the date of application; In Britain, the protection period is 5 years from the date of registration, which can be extended for 4 times for 5 years each time; In the United States, the protection period is 14 years from the date of issuance of the certificate; In France, the protection period is 25 years from the date of application, which can be extended for another 25 years after the registrant declares. It can be seen that the protection period of design patents in China is relatively short compared with developed countries. How long is the protection period of American design patents?
