Our prevention measures to face the COVID-19 pandemic

To our clients and partners: Gastão Cunha Ferreira has adopted all the recommended prevention and security measures in order to combat the COVID-19 pandemic.

For this reason, following the guidelines communicated by the Portuguese Directorate General of Health, we have implemented mechanisms to enable the continuity of our office’s business activity. Relying on remote work, all employees at Gastão Cunha Ferreira are currently performing their daily duties by telecommuting. We thus ensure that all the usual operations of our office continue to be carried out without any interruption or alteration.

We will continue to closely monitor the unfolding of the current situation and we will communicate any further developments to our clients and partners in a timely manner.

Should you have any questions or concerns, we will, as always, be available to assist you.


Our firm is headquarted in Lisbon, Portugal.

We are located in one the oldest and traditional neighbourhoods in Lisbon, with a privileged location in front of the Portuguese Patents and Trademarks Office.

This allows us to act rapidly and effictively on any matter that may arise, and that requires our intervention before the Portuguese PTO.
