Annuities fees are divided into two parts: official costs paid to the government and professional fees. Official fees are dependent on the year you are settling the patent annuity for and the type of applicant who owns the patent. Official fees range from TND 59.5 to TND 595 due on the 20th year. Official fees typically increase year over year over the life of a patent. Professional fees varies between USD 100 and USD 250.
