A Texas court has dismissed a lawsuit accusing pharmaceutical CBD maker GW Pharmaceuticals of violating another company’s patented method of cannabidiol extraction for its epilepsy drug Epidiolex.
The 2020 lawsuit from Canadian cannabis producer Canopy Growth alleged that GW, now part of Jazz Pharmaceuticals, knowingly used a Canopy-patented cannabis extraction method.
U.S. District Judge Alan D. Albright ruled in favor of GW on Feb. 25. His ruling leaves a path for Canopy to appeal he decision.
During the course of the case, GW produced “confidential technical documents” about their manufacturing process, Albright wrote.
Subsequently, the court interpreted the meaning of a specific technical term in Canopy’s patent, “CO2 in liquefied form under subcritical pressure and temperature conditions.”
In light of GW’s documents and the court’s interpretation of that term, the ruling noted, Canopy determined it “cannot prevail on the issue of infringement.”
Smiths Falls, Ontario-based Canopy has the right to appeal the court’s interpretation of the patent term in question.
GW, headquartered in the United Kingdom, was acquired by Jazz Pharmaceuticals in 2021.
On a Tuesday investor call, Jazz CEO Bruce Cozadd said the company was “pleased with where the court came out on the final judgment in the litigation with Canopy.”
Epidiolex is made from CBD extracted from marijuana grown in the UK.
“They do have the right to appeal that, but we’re certainly pleased with where we stand,” Cozadd added.
A Canopy spokesperson said in a statement to Hemp Industry Daily that, “as this matter is still ongoing and before the courts, Canopy Growth will not provide further comment at this time.”
