First of all, it is necessary to confirm whether the declared patented technology of Q has been made public by the State Information Bureau. It is disclosed that the above three technical features are all existing technologies and can be used to judge novelty and creativity. Only novelty can be judged, if before and after the declaration. The criteria for judging novelty and creativity are determined according to the Patent Law, detailed rules for implementation and review guidelines.
In addition, it depends on whether you want to apply for an invention patent or a utility model patent. Practicality is easy to authorize and does not require strict substantive examination. Of course, authorization is one thing, and whether it can be protected is another.
The authorization of invention patent should meet three characteristics: novelty, creativity and practicality. It is creative to judge the creativity of Q patent literature as a comparison document, apply for a patent of B or C alone or apply for a patent of B+C, and retain all the original functions or bring unexpected technical effects after omitting one or two elements.
It is best to analyze specific problems.
