Following implementation of the Decree 38308-JP published on April 24, 2014, payment of yearly maintenance fees for all patent applications filed in Costa Rica as from April 25, 2008 will be due within a 2-month term after grant.
In particular, it will be necessary to pay all the outstanding annuities (for all previous years from filing to grant with exception of the first annuity which is included with the official filing fees) within said term. The amount of official fees for each annuity is USD 500.
Subsequent annuities should be paid every year by the last day of the anniversary month of the filing date. Late payment of annuity fees will be possible within a 6-month term under payment of an official surcharge (USD 125 per belatedly paid tax).
We therefore recommend that you confirm that all outstanding annuities of your granted patents filed in Costa Rica as from April 25, 2008 are being paid. We have already done that for the patents under our control.
Should you require any further information, please merely let us know.
