American trypanosomiasis is a neglected tropical disease and an endemic problem in 21 Latin American countries, whose treatment relies on only two US FDA-approved drugs: benznidazole and nifurtimox. Patent literature reveals vital information on new trends in therapies for various diseases, including Chagas disease. The authors used the patent databases of the world’s major patent offices to generate an overview of patent trends related to the treatment of Chagas disease. A total of 50 patent families were collected and grouped as 'small molecules', 'pharmaceutical compositions of known compounds' and vaccines. From the results and interpretation, it can be concluded that the treatment of Chagas disease receives little attention in the field of patents and that the upward trend is minimal.
