Is it better for junior high school teachers to apply for new patents to evaluate their titles or invention patents?

The gold content of invention patents is higher, but it usually takes 1 year and a half to about 2.5 years, and the examination time is very long. At present, the examination of invention patents in China National Intellectual Property Administration is very strict, so it is difficult for ordinary inventions to pass. If it is a professional title, it is recommended to apply for a patent for utility model, so as to supplement the quality by quantity. Of course, it depends on your school's grading standards.
