RE:Canopy Growth sues GW Pharma for CO2 ExtractionCanopy will fail. Since the technology has been around since the mid-1980s Canopy's 2000 patent is worthless as it was obvious in 2000 that Supercritical Fluid Extraction could be applied to hemp and cannabis. Good thing Canopy only paid $1.00 for it.
For GW Pharmaceuticals to win, the company will have to demonstrate that its method, described in broad terms on its website, uses technology not claimed in Canopy’s patent—or that the technology that Canopy’s new patent claims were “known or obvious” in 2000, when the patent application was filed.
