Writing six utility model patents a year can be said to be quite a good standard. This figure shows that you have good innovation ability in this field and have begun to accumulate patent assets. However, this does not fully reflect the quality or value of your patent. The authorization, technical content and commercial value of the patent you wrote should be your consideration.
Generally speaking, writing six utility model patents a year is a very good start. If you continue to work hard to improve the quality and value of patents, you may be awarded more patents in the future and become a valuable asset of the company.
