In addition, the use of IIP patent DB file is restricted to the scientific purpose only, and it cannot be used for any commercial purpose. Only the person who agrees to the following User Agreement can use this data file.
Outline of data files for the IIP patent DB
The IIP patent DB was created based on the arrangement standardization data to the 23nd creation in 2011 fiscal year, and consists of the following five data files (ASCII CSV file).

Since each data file has large capacity, it is offered by the compressed file (zip form).
Please uncompress and then use.
Please note that it may take long time to transfer the data when the internet is connected in a narrow band such as a regular telephone or ISDN lines, since the compressed file has also large file capacity.
Moreover, since each data file (ASCII CSV file) has many records, it cannot be opened by Microsoft Excel. Please execute data conversion and use with DB software.
Please refer to this document when you use the IIP patent DB.
