We’re collecting and curating all the cannabis data we can get our hands on.
Our aim is to provide enough evidence of prior art to keep overbroad patents off of cannabis plants that exist in the public domain – and to create an open data set about the diversity of the species while we’re at it. Below you’ll find links to the OCP Database as well as a list of External Data Resources.
