Estudo de propriedade intelectual sobre biopolímeros

Abstract

The discovery of polymers revolutionized the daily life of mankind, enabling the development of different types of materials, which provided the expansion of industrial production. The increasing limitation of the availability of fossil raw materials, the consecutive increases in oil prices and the increase in the relevance of sustainability are reasons that have been strongly motivating the development of polymers from renewable sources, biopolymers. This work aims to analyze the deposits of national and international patent applications that present terms related to “Biopolymers” based on the National Institute of Industrial Property (INPI) and the World Intellectual Property Organization (WIPO), in the period between July 2007 to July 2017. Considering the data collection carried out on these bases, the total amount of patent deposits for biopolymers was identified, 5603 at WIPO and 143 at INPI, and the amount of deposits over time was approximately 509 annual deposits at WIPO, while the INPI had an average of 13 annual deposits. With regard to data on patent applications for biopolymers at the INPI, the countries with the largest number are the United States of America with 30, the Netherlands with 11 and China with 10. The analysis of the number of deposits per state in Brazil shows Bahia with 15, São Paulo with 11, Ceará with 8 and Paraná and Rio Grande do Sul with 7 orders each. In the typology category of depositors in international deposits 42% are from companies and 5% from universities, in national deposits 7% are from companies and 37% from universities. At the INPI, the average waiting time between the filing date and the date of granting the biopolymers patent was 33.4 months. The most representative technological areas are sections C (Chemistry and Metallurgy) with 52.44% and Section A (Human Needs) with 37.06% of patent applications. As for the subclasses within these sections, we have: C08B with 11.20%; C12P with 9.80%, C08L with 4.90% and A61K with 17.50%; A61L with 6.29%; A01N with 4.90%. It is concluded with this study that it is necessary to establish concrete measures to encourage research and the university-company partnership, as a way of stimulating the development of technological innovation.
