Advanced Search


Advanced Search provides a count feature that lets you preview the number of patents in your search result. You can combine, filter, and view the match results on the search page for more accuracy before running the search.

Building a Query

On the top part of the Advanced Search page, you can build queries and preview the results.


  1. Select a search parameter from the dropdown list.
  2. Type a keyword in the query box. When entering multiple keywords into one query box, do not include punctuation marks such as commas.
  3. Choose a Boolean operator (AND/OR) to set the relationship between the multiple keywords in the same query box.
  4. You can directly input syntax codes and form query strings (see all syntax codes here).
  5. Click on View Results to view the number of patents of your query on the right.
  6. You can save this query line and the result to the Search Report below by clicking on Save to combine queries later or clicking on Reset to start a new query.


Search Report

On the bottom part of the Advanced Search page, you can combine the queries you saved and view the results in the Search Report box. 


  1. Click on Combination to combine the multiple queries you have saved in the Search Report box. 
  2. Enter or click on the corresponding number of the search queries you want to combine. 
  3. Add a Boolean operator (AND/OR/NOT) after every number to set the relationship.
    (Here, you can see we have added queries No. 29 and No. 21.)
  4. Click View Results to get the number of results for this combined query.

Note: The field under Search Report only adjusts query combinations and does NOT support syntax search. Please use each query No. (as Step 2.) to modify your search scope. E.g., “1 AND 2 NOT 3”


Other functions


Export the Search Report as an Excel (.xlsx) file. See the example below. 



Save an Advanced Search query


  1. Set the Optimum Query (i.e., the combination) by clicking Set as Optimum Query.
    Optimum Query means the significant item of this query procedure. Once you select an  item and set it up, the query procedure will be saved as a recent record in Search History.
  2. Click on the Save Disk icon.
  3. Name the query in the pop-up window and click Confirm.

Remember to save your Search Report before you leave the page to do another task.
