There are three main types of patent databases that can be seen now:

Free patent databases: they are mainly provided by the government, including those from China, the United States and the European Union. These databases have authoritative data, but their shortcomings are slow data update, limited data range, and less rich and friendly functions and interfaces than commercial databases.

Semi-commercial patent databases: such as Innojoy, soopat, Baiteng, etc. Generally, there is no problem in data update and the data range is sufficient, but the general search method, search volume and reading volume are limited. If you want to use it well, you still need several hundred yuan.

Commercial patent databases, such as orbit, Deventer, incopat, patsnap, etc., are used for selling money after all. The data update is no problem and the data range is large enough. Although it is impossible for many countries to use them, their functions and usability will be good. The biggest disadvantage is that they are expensive, expensive and expensive, at least tens of thousands are needed, and some versions may cost tens of thousands.

Originally, innojoy was used more by individuals, and it was completely enough to buy an online 198 package for personal use. However, this week, it was discovered that innojoy's company recently released a "Dawei Patent Database". From the publicity point of view, the current public beta stage is fully functional and free, and it can be used for one month. The biggest highlight is:

Retrieval and reading are free for a long time. Unlimited, unlimited time and unlimited search methods

This makes people very comfortable. innojoy has been doing it for so many years, and it belongs to a semi-commercial patent database. The data is definitely no problem. The related functions should be relatively mature after being polished by the old mice of innojoy users, so it is decisive to register, and the result is really surprising! Let's talk about the entrance first. Baidu Search is a software official website. Just click Login/Register.
