GW Pharmaceuticals’ research on the therapeutic use of cannabinoids dates back at least two decades.
One of the earliest patent applications was in 2002.
In some cases, patents were not assigned until a decade after application.
For example, a patent on the use of cannabinoids for nausea and vomiting was filed in 2003 and granted in 2011.
A patent for cancer- related pain was filed in 2005 and assigned in 2012.
Following is a sample of some of the patents held by GWPH.
Multiple applications are still in the application stage, having been submitted for approval.
