Identification of patent classification

In this method, we can visualize preliminary search results by text mining and compile patent classifications assigned to clusters, enabling us to comprehensively identify patent classifications compared to " Identify the CLSs. Part 2.".

Select Patent analysis by patent text mining from Search Result Control created by preliminary search.

Then, the preliminary search result is visualized based on document similarity.

When you can identify the patent group that has high relevance to this search target, hold down the shift key and select it by dragging and dropping the mouse all at once.

After selecting the patent document, select "1st" from the menu displayed by right-clicking and set the "1st" flag in all the selected patent documents.

After setting the flag, click the " CLS Table" button arranged in the upper left.

The patent classification table screen opens, and the patent classification given to the patent document to which the flag is set is totalized.

While looking at which patent documents the patent classification covers, look for the appropriate patent classification and patent classification hierarchy.

If you find the appropriate patent classification, click the "book" icon and save the patent classification to CLS Table.
