Patents by disease or condition for NTD, 2000 to 2012

One rough (but imperfect) measure of research and development activity are the number of patents that include a disease or medical condition in the patent specification. The following counts are from the US Patent and Trademark Office (USPTO) issued patents for the years 2000 to 2012.

The high number for Leprosy seems surprising, as do the numbers for Chagas and other some diseases.

How does this compare to other diseases and conditions? Over the same period, the USPTO issued 82,365 patents that mention cancer in the specification, 39,127 that mention diabetes and 12,022 that mention dementia. Among so called Type 2 diseases, USPTO issued 11,734 patents mentioning Human immunodeficiency virus in the specification, 10,400 mentioning tuberculosis, and 6,533 mentioning malaria.
