What should I pay attention to when applying for patent authorization?

China's Patent Law stipulates that the design of the patented "Western Pipe" should be different from and not similar to the design publicly published in domestic and foreign publications or publicly used in China before the application date. Specifically: 1 and "different" are patents granted, and the design of Xibuguan should be novel. It can neither be identical with the existing similar products in appearance design, nor can it be an imitation or plagiarism of them. 2. "Inconsistency" means that the patented design should be original. It can neither be a simple imitation of the appearance design of existing similar products, nor be slightly different from what only technicians in this field can see, but should be obvious differences and changes that the public can see at a glance. "Publication" and "public use" have the same meanings as inventions and utility models. In our daily life, we can often see some patents. If you want to apply for protection, you must have three characteristics stipulated by law in order to be protected. When applying for patent authorization, we should pay attention to the relevant time nodes, especially the application date.
