Chinese patent application and authorization data
Data Introduction
Innovation is the driving force of economic growth and social progress. It is the strategic direction pursued by every company in every country in the world, and it is also a hot topic in academic research. Patents not only protect innovation achievements, but also have the function of measuring innovation achievements. Therefore, top domestic and foreign journals and think tank reports regard the number of patents as one of the important indicators for measuring the innovation level of countries and enterprises.
However, we found that many existing studies are conducted on listed companies, and listed companies obviously have the problem of "survivor bias", which requires us to use a larger sample to conduct research on Chinese companies and even regions. research on innovation. With the emergence of large databases such as industrial enterprise data, tax survey data, and customs data, more and more scholars need full-sample patent application and authorization data to conduct higher-quality research. Taking this opportunity, we launched a full sample of patent applications and patent authorization databases.
According to Chapter 1 of the Patent Law of the People's Republic of China, patents are divided into three categories: inventions, utility models and designs, specifically,
Invention refers to a new technical solution proposed for a product, method or improvement thereof.
Utility model refers to a new technical solution proposed for the shape, structure or combination of a product that is suitable for practical use.
Appearance design refers to a new design that is aesthetically pleasing and suitable for industrial applications, based on the shape, pattern, or combination of the product, as well as the combination of color, shape, and pattern.
According to Chapter 4 of the "Patent Law of the People's Republic of China", during the patent review and approval process, invention patents will distinguish between two processes: "publication" and "authorization". Specifically, < /p>
After the Patent Administration Department of the State Council receives an invention patent application and determines that it meets the requirements after preliminary examination, it will be announced immediately after eighteen months from the date of application.
Within three years from the filing date of an invention patent application, the patent administration department of the State Council shall conduct a substantive examination of the invention patent application and make a decision on modification, rejection or authorization. The invention patent right shall take effect from the date of authorization announcement.
If no reason for rejection is found after preliminary examination of a utility model or design patent application (substantial examination is not required), the patent administration department of the State Council shall make a decision to grant a utility model patent or a design patent. Utility model patent rights and design patent rights take effect from the date of announcement.
Based on the above regulations, our patent application and authorization database is divided into tables according to four categories: Invention publication, invention authorization, utility model, and design, and retains all indicators of each patent. content.
Another important thing that distinguishes the patent application and authorization database of the CnOpenData platform from other databases is that our data contains all transaction information for each patent, including when the patent was authorized after application, whether All content related to changes in patent information such as the application being withdrawn after publication, whether the patent is pledged, changes in patentee information, and termination of patent rights.
