Cannabis Producer Canopy Sues GW Pharmaceutical Over Patent

Canadian cannabis company Canopy Growth Corporation is suing GW Pharmaceuticals in U.S. Federal Court charging patent infringement. The allegation is GW uses a Canopy-patent to extract CBD oil according to a complaint filed in the U.S. District Court for the Western District of Texas. The specific patent covers a method of cannabinoid extraction using carbon dioxide. Canopy acquired the intellectual property when it purchased the German company Cannabinoid Compound Company in 2019.

The U.S. patent was issued to Canopy on the same day the lawsuit was filed against GW. Canopy brought this action to put a stop to GW’s knowing and unauthorized use of someone else’s intellectual property. Canopy is seeking damages for the infringement as well as enhanced damages due to the willful nature of the violation.

U.S. sales of the CBD formation comprises over 85% of their revenue for the business quarter ending September 30, 2020. The U.K. based company said in an e-mailed statement they are aware of the lawsuit. GW went on to say “As a policy we do not comment on any pending litigation except to say that based on our preliminary review of the complaint, we are confident in our position and will vigorously defend against this lawsuit.”

A lawsuit like this would likely not have been taken seriously just a few years ago. Today, thanks to research dollars and hard work from cannabis entrepreneurs this happened!
