What are the ways to inquire about patents in China?

In the era of competition, people's innovative spirit and creative consciousness are constantly discovered. The continuous exploration of these spirits and wills has made important contributions to economic construction and led to the rapid development of today's economy. With the expansion of profits, people's awareness of intellectual property protection is stronger, and the registration of patents and trademarks has become the goal of countless experts. However, in our life, if you want to inquire about such China patents, what are the ways? After all, patent registration is complicated now, and many people will worry about whether the patent they applied for has expired, so you should remember the way to inquire about the patent. Specific methods are recommended as follows:

I. National Intellectual Property Website

At present, in our country, as long as you apply for a patent successfully, you will basically attach the patent number. So as long as we enter the patent number on the national intellectual property website, we can know the details of the patent. As the preferred website, it was actually controversial at first, such as slow retrieval speed. However, after many complaints, this website has been greatly revised and the retrieval methods have become diverse. Now there are classification number query, family query, citation query and so on. So I suggest going to official website. 1, the data is updated very quickly. 2. China has the most complete data. There may still be various problems in official website today, but the data coverage is still very satisfactory. Although other methods are also free, they are still not as good as those in official website, and many commercial libraries will be short of weight.

Second, Baiteng.com Supai

Speedpost: This website should be the database with the fastest response, the highest daily activity, the most extensive contact between agents, enterprises and institutions, and its function is free. But putting it in the second place proves that it still has shortcomings, such as slow update. It may take 3-4 months to check the latest patent information. Baiteng: Compared with the last Speedmaster, Baiteng's biggest advantage is that the interface has been optimized. However, compared with the national intellectual property website, it still has disadvantages. 1, slow update; 2. The data information found is not comprehensive enough.

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