Why is the annual patent fee for the fourth year 270,900?

This is a case of deferred payment of annual fee. When the applicant is a company or two or more individuals apply at the same time, the annual fee for the first three years will be delayed by 30%, and the annual fee for the fourth year may be 30% of 900.

900 is definitely not a slowdown, or it may be the first three annual fees stipulated by the slowdown. For example, from the first year, the first year to the third year. In the fourth year, it will not be reduced, but will only be paid according to normal standards.

The premise of mitigation is that the applicant's economic ability is limited. For example, if an enterprise applies for a patent and can provide a loss certificate issued by the competent department for three consecutive years, it can get an annual fee reduction of 80%. Individuals who apply for patents can get 70% annual fee reduction if they declare an annual income of 3,000-5,000.
