How much is the patent? How to calculate the price offered by the patent agent for the applicant?

There is no standard for this in the industry. As far as our firm is concerned, foreign applications are generally drawn at the ratio of 300-450 each. Domestic charges are about 150 to 400.

In fact, some firms do not charge fees for drawings of inventions or utility models, and these fees are included in the agency fees, that is, they are all-in. Actually, you can just ask the agent's office directly.
