Patent applications in Brazil on veterinary antiparasitics.

Abstract

Brazil is an important cattle producer and the world's third-largest pet market, with the second-highest number of dogs. This makes antiparasitic drugs crucial in the animal health sector, addressing a wide range of parasites affecting livestock and pets. This study presents an analysis of patent filings concerning veterinary antiparasitic drugs in Brazil, spanning a 25-year period from 1997 to 2022. Data were extracted from the INPI (National Institute of Industrial Property) database, identifying 66 patents for antiparasitic compounds. The patents were categorized based on their status, type of applicant, and origin. The study also highlights key historical milestones in Brazilian veterinary parasitology and identifies significant global legal issues influencing the evolution of patents in this field. Findings show that companies dominate the patent landscape, with São Paulo and Goiás leading in the number of filings, while the United States is the top non-resident applicant. This study provides a comprehensive overview of the current state of innovation in antiparasitic drugs in Brazil, serving as a basis for further research and technological advancements in veterinary parasitology.
