Patent term extensions are available in Costa Rica as an adjustment of the patent term due to delays in the patent registration process or regulatory approval of a pharmaceutical product.

The Costa Rican Patent Law provides that patent term extensions are available for patents filed after April 25th 2008 and in the following cases:

  1. When the Patent Office takes more the 5 years to grant the patent, from the date of filing in Costa Rica, or from the date it entered the national phase in Costa Rica for PCT applications.
  2. When the Patent Office takes more than 3 years to grant the patent, from the date examination was requested.
  3. For pharmaceutical products, when the approval for sale by the Ministry of Health has taken more than 3 years from the application.

Actions attributed to the applicant will not be taken into account to calculate the delays. The term to compensate will be 1 day per day of delay, as long as the remaining term of the patent does not exceed 12 years. Nevertheless, the total term to compensate shall never be more than 18 months.

The request to apply for patent term compensation shall be filed by the applicant with the Patent Office no later than 3 months after the patent was granted, or 3 months after the marketing approval was issued by the Ministry of Health.

An interesting fact is that patent term compensation was introduced into the Costa Rican Patent Law as a consequence of the enactment of DR-CAFTA, the Central American-Dominican Republic Free Trade Agreement with the United States, which means it should also be available in all the other countries party to the agreement, which are Guatemala, Honduras, El Salvador, Nicaragua, Dominican Republic and the United States.
