The arrival of 2019 has brought with it many changes to Brazil’s IP market, as well as its political landscape. On 1 January, Jair Bolsonaro stepped into his role as president; since then, there have been some sweeping reorganisations at the National Institute of Industrial Property (INPI). INPI has been made a part of the newly formed Ministry of the Economy, which now comprises four different ministries, including the Ministries of Industry, Foreign Trade and Services (of which INPI was a part under the former government). The agency also has a new president, Cláudio Vilar Furtado, whose principle tasks will include dealing with its ongoing application backlog – currently standing at more than 200,000 pending applications. INPI has launched a new strategic plan to streamline procedures by 2021. Having recently announced a technical partnership with the American Chemical Society, it will also be using AI tools to expedite examinations. In addition, a pre-examination office action pilot project has been initiated to simplify the application process. Although this will not replace substantive examination or act as a fast-track programme, it will provide an opportunity to check whether applicants are still interested in pursuing their applications by the time that they are ready to be technically examined. The project is already reported to have increased INPI’s productivity rate and is steadily reducing the backlog of applications. The INPI Green Patent programme – a scheme under which patent applications relating to environmentally friendly technologies are to be expedited in a grant time of approximately two years – has also taken the market by storm. Moreover, numerous prosecution highway agreements remain in force with Japan, China, the United States, the United Kingdom and the EPO.

The outfit’s illustrious following of French and German-based patrons greatly appreciate its superb in-house translation services and overall quality. “Bhering has a very strategic and pragmatic approach, resolving issues quickly and efficiently. The difference between it and other firms? Its practitioners listen to us and understand our in-house strategy.

This feedback was not atypical, with many similar impressions of the outfit’s outstanding contentious and non-contentious capabilities gathered over the course of our research. “It’s the absolute first name on the list for litigation, always on the other side of the courtroom. The most important competitor for sure.” “It leads the patent landscape, partly by virtue of its sheer size, but also due to the fact that it doesn’t seem to make mistakes.” “Tradition, a high number of clients and its volume of practitioners makes Dannemann Siemsen the main IP firm in Brazil.” The practice truly does it all, carrying out patent work of every type on behalf of an enviable client base that includes pre-eminent global names across various industries and sectors.
