Creativity is to have a comparison document as the closest prior art, and then combine common sense or other comparison documents with the closest prior art to comment on this application.
Therefore, creativity requires a higher degree of patent application.
For example, this application protects a chair with a cushion to improve comfort.
The reference document 1 discloses a chair, but does not disclose a cushion.
Setting a cushion on a chair is a conventional technical means used by those skilled in the art to improve comfort.
Therefore, comparing the document 1 with the conventional technical means in this field, we can draw the conclusion that this application is not creative.
If the reference document discloses a chair with a cushion, and its purpose is to improve the comfort, the application is not novel compared with the reference document.
