First of all, according to Article 42 of China's Patent Law, the term of invention patent right is 2 years, and the term of utility model patent right and design patent right is 1 years, all of which are counted from the date of filing. That's right, but this is only a regulation of our country, and foreign regulations are not consistent with those of China. It depends on which country's laws apply, and this is related to the conflict of laws or political treaties in international law.
Secondly, the statement on the first floor is wrong. The reason why a trade secret will not be used by others is that it is a secret. If it is known by others, others can use it as they want. The so-called trade secret refers to the legislation that is not known to the public, can bring economic benefits to the obligee, is practical, and has been protected by the obligee's technical information and business information. It never only protects the legitimacy of maintaining the secret. If it illegally infringes on the other party's trade secret, it can only seek legal protection for the infringing act and impose legal sanctions, but the result of the infringement cannot be protected. So you said that McLaren got Ferrari's information, and the alliance can only punish it for infringement, but can't prohibit its use.
Finally, Quattro technology is a technology in the early 198s ... Besides, Quattro technology is just a general term. If improvements are made, such as the second generation of Quattro technology, new technology products can apply for new patents, and new patents are also new protection periods, so as long as there is innovation, there is no fear of not being protected by law <
Supplement: Yes, the Beetle is a product of 193s, and it has already passed the protection period as a design. However, the Volkswagen Beetle was not a product of the 193s. The official name of the Volkswagen Beetle was Volkswagen Type 1, which was a compact car produced by Volkswagen from 1938 to 23. In 1998, many years after the original Beetle rolled off the assembly line, Volkswagen officially launched a new Beetle (on the platform of Volkswagen Golf), which was produced in Mexico and a few other countries until 23. And the Beetle you mentioned is the new Beetle you see on the market now ...
Beetle is a relatively large category, and Volkswagen Beetle is one of the specific new designs with independent innovation significance. For example, if you build a Ferrari sports car and I build a Lamborghini sports car, it can't be said that I will infringe on you.
if Chery independently develops a beetle that is not used by the public, there is no infringement, but it is an imitation of the beetle of the public, which will definitely lead to lawsuits.
as for the identification of the design, there are standards, and it is also a flip cover. If you can flip it forward, I will flip it over. If it is not, I will slide it over. In short, it is not infringement if it is different from you. ..
