The Charlotte's Web strain has been officially recognized as an invention by a patent issued by the US Patent Registrar, the US body validating technical innovations
This patent is unpublished for cannabis. The strain contains less than 0,3% THC, which categorizes it as "hemp" according to US law in force since December 2018. The strain is registered under the number CW2A. It is particularly resistant to low temperatures. Its particularity lies in its ability to produce on average 6,24% of CBD and only 0,27% of THC.
This low THC content opens the door to categorization as "hemp", as defined by 2018's American Farm Bill, which states that beyond 0,3%, no cannabis plant can fall within the strict definition of hemp.
The strain "Charlotte's Web" owes its fame to Charlotte Figi whose name gave its name to this variety, a young epileptic with Darvet's syndrome. His symptoms are drastically reduced, allowing him to have a normal life. This story was then in the headlines of the press and international media.
The company "Stanley Brothers", made a patent filing in May 2018, and in July 2019 the company finally received its patent, becoming the first to obtain it for a strain of cannabis.
This is what looks like patenting of a cannabis strain.
