What are the free patent search site? Top ten free patent search website introduction free patent search website which? Top ten free patent search website introduction a, soopat ,I ranked in the first place, because I personally feel that it is the promoter of the influence of the whole industry situation, precisely because they changed the domestic situation, in the long run, can change the world situation. And this time, it can be said that soopat on behalf of China's patent search in front of the world. Specific content is not introduced, please see my previous article: non-advertising post; recommended soopat's patent search function. Advantages: fast speed, more complete data, the feeling of foreign data is not complete. Cons: revamped too quickly, a lot of good features I think very good to use, are changed. Second, wisdom buds This is my new found a website, there are Chinese and English URL. Many of its places have the same place with soopat. But there are also a lot of originality, such as export and reminders, in some features, is not soopat. In addition, on the help page, it is very good to use, there are lists, pictures, and videos, which are not comparable to other websites, and it is easy for new users to get started. Pros: lots of features, good help, analyzing interface borrowed from Derwent. Cons: incomplete data. Third, Bai Teng Bai Teng was originally a company selling patent search and analysis software, this platform is one of their best product display. Because it is a display, so the feeling is just to serve for the BaiTeng network, rather than an independent search platform. For example, URL, just use so, same as soopat front-end. I feel completely unnecessary, you can use sou, or directly with s. And in terms of functionality, I feel that compared to soopat has some increase. Especially domestic patents, in addition to valid and invalid, but also can be cited whether there is a transfer of rights and other information, this feature is unique to Baoteng. Other functions are not as good as the above two websites. Advantages: Practical functions. Disadvantages: international data is more complete, the amount of analysis is only 5000. four, this is said to be a Singaporean website, they have been claiming to be the world's largest concept of search engine. My understanding, it is the intelligent search, said the computer is better than the censor. But I don't think so. My personal knowledge of artificial intelligence suggests that this is unlikely. Features: conceptual search. Cons: incomplete data, not enough features.
