What our clients say

I have been working in the business world for a long time, and I have had to manage several IP projects. After all these years, I can assure that I have never met any offices with the same level of professionalism, confidence and hard work as Rosalía Ballester’s. They work very hard and choosing them is a guarantee of success. Thank you for your commitment.

At Burning Rubber we take licensing seriously and represent a range of what we call ‘Petrol-head’ brands for the European market, which include Gas Monkey Garage, Orange County Choppers, Exile Cycles, Salinas Boys, Quarter Mile and TVR. Ballester IP have helped us to tackle the challenges we face resulting from the sale of counterfeit apparel found in our market and in addition helped us to apply for and secure Trademark protection for our own brand ‘Los Tremendos Latinos’ which will be sold in Europe and the United States. Their communication and attention to detail is excellent and we expect to benefit from their expertise for many years to come.

Eugene McElhattonCEO | Burning Rubber Co.

I have counted upon Ballester IP’s support for over 12 years to develop my patent portfolio and I can highlight their high qualification, professionalism and quality in IP management. I can also emphasize that Rosalía and her entire team have offered me their professional honesty and accompaniment during this difficult road towards achieving the grant of every patent.

Carlos Alberto Pérez LafuenteCEO | Afirma Consulting & Technologies, S.L.

From our beginnings as a start-up, to wherever we can get, one of the secrets of our success will be to walk beside the Ballester IP team. They are always attentive and focused on our interests, which they make their own, so they go beyond the strict development of their work as professionals, so thank you!

Ramón Villot SánchezLegal & Compliance Director | Facephi

I have worked with Rosalia and her team for many years. They are always very responsive and very creative in their approach to IP issues. They are also good people. In short, they are a delight to work with and I hope to work with them for many years to come.

David SilvermanPartner | Davis Wright Tremaine LLP

After almost a year working with Ballester IP to protect our trademarks worldwide, we have taken a huge step thanks to their knowledge and experience. They are a great team, regarding both personal and professional treatment. To us, it is as if they were a part of our company.

Aurélie ZogheibMarketing Director | G’s España Holdings

Working with Ballester means having the peace of mind of having an internal staff member who is professional and competent, who provides continuous monitoring and not having to pay a salary at the end of the month.

Piero PiacentiniGeneral Manager | European Television Service

After more than 75 years of industrial experience, with over 500 patents, including industrial designs and utility models, Ballester IP can be defined by their transparency, rigour, and professionalism. Investing in research, development and innovation is currently highly complicated. Therefore, fully knowing the means for protecting talent and creativity and thus ensuring that your rights factually prevail, becomes crucial for a deeply rooted Spanish manufacturing firm whose brand has been an industry leader for over 75 years. Really getting to know the meaning of “intellectual property” and “trademark value” meant a great deal for developing our new strategy. There is a huge difference between what it is [definition] and [what we discovered] thanks to Ballester IP’s team.

Alberto HerranzFominaya S.A.

Rosalía Ballester and her team have been responsible for many years for our broad trademarks and patents portfolio worldwide. Not only have they helped us to manage our trademarks in a more effective way, but they also worry about keeping a transparent and fluid communication with us in order to get the most productive use of our portfolio in the simplest way possible. There is no doubt that they are professionals committed to their clients.

José Luis José CháferGeneral Manager | Laboratorios Forenqui S.A.

It is a constant challenge and a huge responsibility for our team to be in charge of the trademark and domain portfolio of an international company such as Viña Concha y Toro, present in over 140 countries with direct distribution, and it would not be possible without the counsel of high-level, reliable, straightforward and clear attorneys-at-law such as the services rendered by Ballester IP through the attorney-at-law Rosalía Ballester and her team. We have worked with other Spanish firms but it is hard to find the confidence and proximity inspired by Rosalía, especially when her work is successfully completed with such good results as those obtained since we entrusted our IP matters in Spain to her and her team more than a year ago.

Paz RosasHolding Concha y Toro S.A.

For us, working with Ballester IP’s team means having the peace of mind of relying on true professionals who assist us on managing our IP matters in the best possible way. The closeness of their working method, despite having a full coverage, inspires confidence in such a sensitive issue as protecting the innovation created in our company.

Pedro GaleraTechnical and R&D Innovation Manager | ITC Packaging

Taking good care of a brand’s image for a select product as ours is key. In this regard, we have full trust in Rosalía and her team of professionals, who have always been effective in guiding us with our IP matters. Furthermore, besides their legal advice, they bring their expertise and good judgment as an added value to assist us in defining and implementing our branding strategy.

Antonio LlusarFinancial Manager | Antonio Llusar y Cia

Europe is an important market for our company, and Rosalía and her team have been nothing short of amazing in helping us to protect and secure rights to our most important trademarks in this market.
In one complicated case, Rosalia took over an intractable case from the previous counsel and was able to swiftly bring it to resolution. Her team consistently provides clear, creative and practical advice in a timely manner. They are always responsive and works hard while never losing sight of the practical business objectives of the client. It is comforting knowing precisely who is working on your matters and they are always flexible in accommodating any requests.


Our colleagues at Ballester IP are our go-to firm for patent matters in Spain. We would work with no other firm. Aside from their technical expertise, the attorneys and staff at Ballester IP are truly kind people who always go above and beyond the normal practice to ensure perfection in their work product.

Steven M. GreenbergPartner | CRGO Global

We see Ballester IP as an extension of our in-house legal department. Our collaboration has been seamless, and we know that we can count on their advice being objective and goal oriented. Their organization is top notch but most importantly you can count on a human interaction and a point of reference that will input the time to try and understand the industry specific issue you are facing each time.
