What sets the BKM team apart from other firms is its organisation, capacity for work and response. It is worth acknowledging that all matters are up to date and under control, and they are always available to answer any questions and/or comments.

The speed, response, capacity and attention of Valeria Carron from BKM | Berkemeyer is a plus for the firm, since in dealing with her in daily work, she denotes being a lawyer committed not only to her work, but also to her firm.

We have worked with BKM for a long time now, and always feel our matters are being duly dealt with in Paraguay. The team is great and responsive, and the intellectual practice includes both patents and trade marks.

Individuals at the firm both in the trade mark and patent field are always reachable and ready to assist in whatever issues may arise. Barbara Dollstadt is our contact for trade mark matters and Cristobal Gonzalez, for patent cases. Both are very competent and efficient in providing useful advice for the handling of our IP matters in Paraguay.

We have worked with Berkemeyer for more than 18 years and it has been a pleasure for us. From them, we have learnt good practices, handling of important information, complete reporting and received unprecedented attention. Berkemeyer is a hub for any client looking for top service in countries with difficult jurisdictions.

We have worked hand in hand with Valeria Carron who constantly sends us work for the Central American area and it is a delight to work with her. We have seen how Valeria has emerged as an increasingly outstanding professional.

The most important part of the excellent experience I have with Berkemeyer is the people. My main point of contact, Valeria Carron, exceeds all expectations across all possible measurements. She is the most responsive, diligent, and accurate attorney with whom I have ever worked. She is also an absolute pleasure to work with. The rest of the team follows Valeria’s lead and her outstanding supervision. I simply cannot say enough to praise her and her team.

Berkemeyer has a fantastic network of professionals in the Latam region. They have a staff that is capable of servicing large needs at a very high-end level of service.

Vouga’s business language is characterised by its ability to convey complex legal issues in simple terms. The firm is always quick to adapt to new legal landscapes in our ever-changing commercial projects, always keeping in mind our ethos and the necessities of our business and our stakeholders with practical solutions, transparent billing, and quick turn-around.

Laura Lezcano always keeps our company and the necessities of our business in mind, keeping us aware of relevant news affecting our commercial interests.

Rodrigo Fernández is a source of extensive knowledge and wide experience in matters of counterfeit products and general IP, always available with sensible advice that keeps in mind the ethos of our company, and our strong focus on compliance.

It is clearly the best law firm that we deal with in our business group, and we deal with most of the large law firms in the country. I clearly see that they invest in technology, human capital, and all the lawyers have a higher level of preparation. In addition, their billing schemes are very clear. Its range of services is wide and all of them of excellent quality.

I think it is an avant-garde firm, led by young people. I know the quality of the work of the brand team: Laura Lezcano, Grecia Florentin. There are other excellent professionals: Manuel Acevedo and Rodrigo Fernández in particular.

I recommend Laura Lezcano and her firm in view of the excellent work they have done for our clients in Paraguay for several years. Laura plays an important role in assisting us to protect our clients’ trade marks in that country. She is very responsive, committed to clients’ interests and goals, and her deep knowledge and wide experience has enabled our clients to obtain the best possible trade mark protection.

Laura Lezcano has also done excellent work with trade mark prosecution and always provides us with enlightening advice regarding the best strategy for our clients to take in terms of obtaining and defending their trade mark rights.
