On November 19, 2003, the Argentine Patent Office issued a resolution, Rule P225, in an attempt to normalize the payment dates of annuities. The new resolution applies to all existing patents in force as of April 12, 2004. The effected types include regular and divisional patents, as well as importations and utility models filed prior to November 1, 1995 and received a 15 year term generating from grant date.
To keep a Argentinean patent in force, a maintenance fee is due in several times during the life of the patent:
1. the first year to the third year
2. the fourth year to sixth year
3. From the seventh year, you have to pay every year, until the protection period is over .
Failure to pay an annual fee produces the expiry of the patent or patent application
