I can not get the search results when I include such words as ‘Application’ in ‘Patent (Industrial Property Rights) Number’.

The information on patent categories (including descriptions such as ‘Application’ and ‘Unexamined Application’) and patent numbers are sometimes registered separately on the database.
Therefore, if you enter descriptions on patent categories in ‘Patent (Industrial Property Rights) Number’ section, sometimes it does not return your intended search results.
In such cases, please delete the descriptions on patent categories and try the search again.
