What's the difference between the invention patent application in Brazil and that in China?

The application procedure of invention patent in Brazil is basically the same as that in China, and the process is as follows: patent application, formal examination, early disclosure, substantive examination and patent authorization.

The difference is that the patent is formally examined within 60 days after the application is submitted; After paying the examination fee, the applicant shall file an application for examination of the patented substance within 36 months from the date of application; Foreigners who have no domicile in Brazil need to entrust an agency to file a patent application, and the power of attorney does not need notarization; The annual fee will be paid in the third year from the date of application.
