The promotion of general titles does not require a high number of patents. It is enough for the applicant to own one or two patents, but it also depends on the specific type of patents. If it's an invention patent, one is enough. If it is a utility model patent or an appearance patent, the applicant can prepare 1-2 appropriately, without too much, so the applicant need not worry too much about the quantity. It should be noted that the position of the applicant in the patent is directly related to the extra points.
Second, the patent matters needing attention:
Engineering title: the first inventor can get 8 points, the second inventor 7.5 points, the third inventor 7 points, and so on. Compared with the former inventor, the difference between the latter inventor and the former inventor is at least 0.5 points, and the difference is not more than 2 points. The sixth inventor doesn't get extra points.
