Why is the patent application so expensive? The student party can't afford it. . .

First of all, the cost of patent office application, no matter how expensive, is inevitable. Among them, what deserves special attention is the substantive review of the fees paid. The staff of the patent office will consume each other's time and energy while examining and inquiring the submitted patent applications. At the same time, in order to ensure that each patent is unique, patent retrieval should be carried out in depth. This workload is very huge, involving the retrieval and query of various free databases in the country.

During this period, the staff will also check the information filled in the patent and the technical contents of the specification to see whether the patent application can really be realized, whether it has the benefits of novelty, whether it meets the authorization standards, and will be given corresponding rights. Then there is the agency fee. Almost any agency charges thousands of dollars for invention patent agency applications. Among them, most of the reasons are that the application for invention patent is difficult, the procedure is complicated and there are many preparations before application.
