"This specialised boutique is a new entry to the market, but benefits from the years of experience gained by the firm's founding partner at one of Brazil's top IP outfits. The group is active in all aspects of IP, including licensing and technology transfer, unfair competition and internet trade mark and domain-name disputes".
Chambers Latin America 2013

PRACTICES
The firm offers prosecution work based on strategic portfolio management that protects intangible assets and prevents lengthy disputes, keeping costs at a reasonable level.
The firm’s consultation services are geared to deliver the best legal advice possible, that takes into account both legal and business considerations.
Licensing and technology transfer services require careful and detailed drafting of license and technology transfer agreements, focused on both the practical and commercial interests of our clients, while taking into consideration the legal requirements and the policies and inner workings of the Brazilian government authorities.
The firm’s litigation and anti-counterfeiting practices handle both highly sensitive strategic litigation and low-cost anti-counterfeiting measures, always with a focus on practical and sensible results, without losing sight of implementing alternative dispute resolution techniques to achieve our clients' objectives faster.

ATTORNEYS
There is a proliferation of smaller firms in Brazil, creating a more diverse market. Some have been very successful and Ouro Preto is one of the best examples.” It was established in October 2011 by Rodrigo de Ouro Preto Santos, a George Washington University Law School LLM graduate and former Arent Fox foreign attorney whose turnaround times are “simply amazing”. “He provides that high-level US or European standard of service that sophisticated companies demand.” His organisation now has three partners, including fellow founder Samantha Bancroft Vianna Braga, an effervescent lawyer with skills across the IP spectrum. The pair have had plenty of opportunity to flex their contentious muscles recently, securing great results through their laser focus on clients’ commercial objectives. They have also proven their ability to get to grips with large-scale international trademark portfolios. Further underlining their excellent credentials, both are very active in IP organisations such as INTA.
