The annuity payment is also known as patent renewal payment enables the patent holder to keep their patents alive in the respective jurisdictions and to restrict others from using, making, selling, and importing your invention in a respective region or country.
Although patent laws can differ from country to country, in most jurisdictions the renewal fee is to be paid annually. However, in other jurisdictions it is only every third or fourth year. The most widespread example of this is the USA, where a patent holder has to renew their patents every 3.5 years.
