RESUMEN
INTRODUCTION: Arenavirus are unique category-A pathogens that are also classified as Orphan diseases. Very few options exist currently for treating Viral Hemorrhagic Fever (VHF) caused by viruses belonging to the Arenaviridae family [1]. The current review provides detailed patent landscape and a description of selected technologies developed for combating category-A Arenavirus. Currently, Arenavirus infections are epidemic [2] but could cause widespread pandemics due to ease of dissemination and lack of immunity against these viruses. AREAS COVERED: The key strings for selected Arenavirus VHF were run separately in MCPaIRS®, PatSeer, and Questel database. The search was limited to Title, Abstract and Claim fields; one member per patent family was considered for analysis. EXPERT OPINION: Synthetic molecules dominate the patent landscape, while natural products have not been extensively claimed for the treatment of Arenavirus infection. The broad-spectrum activity has been highly desired for Arenavirus treatment, but few reports have experimentally tested it. With each year, a constant increase in number of patents published is seen, while the maximum number of applications was filed in 2017. The research in VHF is driven by public funds; the maximum numbers of patents were filed by publicly funded organizations.
