Once an invention patent is granted to operate and maintain it, a patent maintenance fee must be paid annually. If the maintenance fee is not paid, patent protection expires.
By regularly paying maintenance fees, the patent owner's exclusive right, commercially exploiting the invention, lasts up to 20 years from the filing date.
The maintenance and renewal of the patent granted by the operation for a new period of protection shall be entered in the Patent Register, which shall be maintained by the Patent Office. In order to receive statements or extracts from the Patent Register regarding the current status of industrial property rights objects, a written request must be made.
