A Canadian developer of cannabis breathalyzers has been granted its third patent in North America for a device meant to be used road-side by law enforcement and employers to check if a person is high.
On Tuesday, Cannabix Technologies Inc. (CSE: BLO) announced that the United States Patent and Trademark Office (USPTO) granted it a patent called Apparatus and Methods for Detection of Molecules or patent No. 17/019728.
The new patent is centered on updates to its Cannabix Marijuana Breathalyzer technology called field asymmetric waveform ion mobility spectrometry or FAIMS that identifies different molecules from gas, in this case, THC in a person’s breath.
“This patent is the culmination of research and development work conducted by Cannabix scientists and engineers in the areas of ion mobility spectrometry, non-volatile molecule sampling and fluid dynamics.,” reads a statement.
In January, Cannabix was granted its first patent from the USPTO called Cannabis Drug Detection Device or patent No. 14/689434. And in June it was granted a patent under the same name from the Canadian Intellectual Property Office, No. 2887841.
