Soopat, I ranked first, because I personally think it is the promoter that affects the whole industry, and it is precisely because they have changed the domestic situation and can change the world situation in the long run. This time, it can be said that soopat represents China in leading the world in patent retrieval. I won't introduce the specific content, please see my previous article: non-advertising stickers; Recommend soopat's patent search function. Advantages: fast speed, complete information, feeling that foreign information is incomplete. Disadvantages: the revision is too fast, and many good functions that I think are very useful have been changed. Second, Wisdom Bud This is a newly discovered website with Chinese and English websites. Many places have the same place as soopat. But there are also many originality, such as exporting and reminding, which soopat doesn't have in some functions. In addition, on the help page, it is very easy to use, with lists, pictures and videos, which are incomparable to other websites and convenient for new users to get started. Advantages: multi-function, good help, and the analysis interface draws lessons from Deventer. Disadvantages: Incomplete data.

I don't think it is necessary at all. You can use sou, or you can use S directly. In terms of functions, I feel that it has some improvement over soopat. In particular, domestic patents, in addition to being valid and invalid, can also index whether there is transfer right and other information, which is unique to Baiteng. Other functions are not as good as the above two websites. Advantages: practical function. Disadvantages: the international data is relatively complete, and the analysis amount is only 5000. This is a website that is said to be Singapore. They have always claimed to be the largest concept search engine in the world. My understanding is intelligent retrieval, saying that computers are better than examiners. But I don't think so. My personal understanding of artificial intelligence, I think this is unlikely. Features: concept search. Disadvantages: incomplete data and insufficient functions.
