Neptune Files Two Patent Applications for Innovative Cannabis Extraction Processes

Neptune Technologies & Bioressources Inc. has filed two applications with the United States Patent and Trademark Office (USPTO) for patents related to the extraction of cannabis material.

The extraction processes provide highly-efficient methods to obtain cannabinoids and other desired compounds from the cannabis plant at a greater purity than conventional methods. Both processes are applicable to marijuana and hemp and will be incorporated into the company’s Good Manufacturing Practices (GMP)-certified extraction facility in Sherbrooke, QC upon approval of the applicable licensing to produce cannabis extract (pursuant to the Access to Cannabis for Medical Purposes Regulations). As a late-stage applicant, Neptune is currently working with Health Canada authorities to complete the licensing process.

The first patent application outlines a method of extracting and isolating compounds from plants of the Cannabis genus at low temperature by using a cold organic solvent. The second patent application similarly provides for a method for extracting compounds from cannabis at low temperature, but without the use of organic solvents. Specifically, this patent relates to a process for high recovery of cannabinoids and terpenes by using natural solvents.

“After extensive laboratory trial work by our researchers, we are excited to have developed a range of unique and highly-efficient processes for the production of cannabis extracts of superior quality. These patents also reflect the leverage of our many years of experience developing value-added differentiated products based upon science,” said Jim Hamilton, President and CEO.
