How to examine the three characteristics of patent? Novelty, creativity and practicality

1 does not have novelty, and the low position breaks the high position. The reverse is also possible, but it needs to be explained why, that is, the advantage of the low position;

2 is not novel because the value of "4" is between 1- 10.

3 creativity is hard to say, it needs its advantages and beneficial effects to evaluate. And its creative point is "an arc-shaped chair back that conforms to the shape of a human body". What needs to be explained is that it is not obvious and can be thought of, so it is creative. If it is a universal means, it is not creative. A few words are not creative.
