In the era of competition, people's innovative spirit and creative consciousness are constantly being discovered. The continuous exploration of these spirits and wills has provided important contributions to economic construction, resulting in the rapid development of the economy today. The expansion of profits has made people have a stronger awareness of the protection of intellectual property rights, and patent and trademark registration has become a goal that countless experts are flocking to. However, in our daily life, if we want to check this kind of Chinese patent, what is the way? After all, patent registration is complicated nowadays, so many people are worried about whether the patent they have applied for has expired, so everyone still needs to remember how to search for patents. Specific methods are recommended to you as follows:

1. National Intellectual Property Website

Currently, in our country, as long as you successfully apply for a patent, it will basically be accompanied by a patent number. of. Therefore, we only need to enter the patent number on the national intellectual property website to learn the detailed information of the patent. As a preferred website, it was actually controversial at first, such as the slow search speed. However, after many people complained, this website has been greatly modified, and the search methods have become diverse. Nowadays, classification number query, homogeneous query, citation query, etc. are available. Therefore, I suggest that it is better to go to the official website. 1. Data updates extremely quickly. 2. China has the most complete data. Perhaps nowadays, the official website still has various problems, but the data coverage is still very satisfactory. Although other methods are also available for free, they are still not as complete as the official website, and many commercial libraries may be lacking.

2. Supai, Baiteng.com

Supai: This website should be among the existing searches, with the fastest response, the highest daily activity, agencies and enterprises and institutions The most widely accessible database, and its functions are free. However, the reason why it is placed in second place proves that it still has shortcomings, such as slow updates. If you want to check the latest patent information, it may take 3-4 months. Baiteng: Compared with the previous Super, the biggest advantage of Baiteng is that the interface has been optimized. However, compared with the national intellectual property website, it still has shortcomings. 1. Slow update; 2. The data information found is not comprehensive enough.

Let me recommend these three to you. You can try them and choose the one that suits you.
