Knowledge extraction on international markets from patent bases: a study on green patents

Abstract

Goal: This article aims to propose a model for stratifying technological information from meta-data contained in international patent bases, capable of supporting the strategic decision making that potentiates actions directed to foreign trade.
 Design / Methodology / Approach: This applied research was based on the KDD - Knowledge Discovery in Databases methodology and carried out a study focused on green patents. Patent bibliographic data published in the Patent Cooperation Treaty (PCT) from 2003 to 2012, focusing on alternative energies, more precisely on biofuels, were obtained from the Derwent database, with the search string based on the Green Patents IPC Inventory, published by the World Intellectual Property Organization (WIPO). After treatment and sanitization, more than 36,000 resulting records were performed under C4.5 algorithm, denominated J-48 from the software Weka, resulting in Brazil as the destination country.
 Results: A decision tree was established, in which Mexico was highlighted as the main discretionary country. It was also verified the adhesion of the other emerging countries, which, along with Brazil, compose the BRICS.
 Limitations of the investigation: The proposed model is limited to areas that show intensive use of technology in products and processes.
 Practical implications: It could be inferred that the proposed method can help companies to identify international markets more sensitive to a certain technology, from a free database, reliable and capable of being used by micro and small companies.
 Originality / Value: In scientific communication, it is not easy to find Data mining applied to Patent database, and in this study, BRICS cluster were identified in Green patents WIPO deposit.

“…Ao escolher a via do político para entender as estratégias do grupo do PUG-PE, queremos avançar em relação às abordagens funcionalistas de estudos que analisam somente a capacidade administrativa das comunidades em atrair e reter usuários. Essa escolha também permite contribuir com as discussões em vários campos disciplinares, como a visão de que o SL se limita a um debate sobre o avanço natural das TIC, como fazem crer Steiniger, Fuente, Fuentes, Barton e Muñoz (2017) ao analisar os sistemas de informação urbanos como simples implementação de dispositivos eletrônicos, abordar as polêmicas na área de direitos autorais desenvolvidos por Lessig (2004), questões envolvendo as patentes verdes de Bretas et al (2019) ou até políticas públicas de tecnologia, como a proposta de Heikkinen, Savina, Partanen, Seppälä e Pearce (2020) em discutir a estratégia nacional de hardware aberto na Finlândia.…”
