The team is dynamic and they always provide us with prompt responses and good care in matters that we have had the opportunity to work together. Their treatment is extremely friendly which makes it a pleasure to have them as allies in Paraguay for intellectual property.

The IP team is made up of professionals with vast experience in the field. Montserrat Puente, team leader, is one of the most prepared lawyers in this area in the local market, and this differential is noticeable when receiving her opinions on issues that significantly impact our business.

When Ferrere began offering IP-related services, they made sure to recruit the best professionals in the market specialised in that area. The level of response and the speed with which they are issued speak perfectly to the level of pressure we handle in our businesses. Paraguay is a market in which trademark matters take on special importance due to the existence of illicit practices that violate these rights, so it is essential to have the support of good professionals and with indisputable ethics, and the firm has them.

Montserrat Puente is a great professional, who always stands out with her specialised treatment and who attends to all our needs personally, which is very important to us.
