Recommended for these people
- I want to improve search accuracy using a Chinese language database.
- I want to narrow down a massive number of search results using legal status information.
- I want to comprehensively search Chinese patents in English, as technical terminology is not well-standardized in Chinese patents.
Features and Benefits
-
Hybrid Search
Enables hybrid searching in both Chinese and English.
Since applications filed by domestic applicants in China have few foreign transitions via foreign applications or PCT applications, family searches are difficult. For Chinese patents where technical terminology is not well-standardized, you can achieve highly comprehensive and accurate Chinese patent searches by using English, where technical terminology is standardized to a certain extent. -
Status filter search
Searching for the legal status of Chinese patents has been difficult in the past because the China National Intellectual Property Administration uses various notations for legal status and there are also clerical errors.
In the "Japan Server Version of CNIPR," we have corrected these clerical errors in legal status, making it a very convenient feature for narrowing down search results, such as for determining whether a patent is active or expired. -
Highlight feature
You can highlight necessary keywords through user settings.
You can also proceed to the next patent on the screen to view it. -
Bulk download
You can download a list of up to 10,000 items. It is possible to download not only bibliographic data and abstracts but also full claim information.
In addition, you can choose to download lists in Chinese or English. PDF copies of gazettes can also be downloaded. -
History operations
You can perform operations on search history, delete history, and re-run searches. -
Partial match searchPartial match search (string search) allows you to hit not only words but all patents containing the search characters.
Partial match search is possible for titles, abstracts, and all claims, allowing you to obtain highly comprehensive search results.
