Supported patent filings

* Power of Attorney forms must be notarized and legalized via either the Apostille procedure or at a Honduran consulate in your home country - one will suffice for all Central American countries. If a power is not restricted by the grantor to a specific case, it can be used for other matters. The consulate will provide instructions on the procedure; note that costs will be incurred for this.

** The Assignment of Invention must be legalized. We require three Assignment of Invention documents legalized by the Apostille procedure.

*** The Spanish translation can be filed at national phase entry or within two months from the national filing date.
