Three characteristics of patent: practicality, innovation and novelty. How to understand innovation and novelty always feels similar, and it is best to have a case study.

Simply put, novelty means that a comparison document (existing technology) discloses all the contents of your patent application, that is, the technical fields involved, technical solutions, technical problems solved and technical effects achieved are the same.

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.
