The "deal" with UF was a research grant to develop the breathalyzer which ran a specified term. That has concluded. If more development effort is needed it would be reasonable to assume that another grant would be needed to fund it. That is separate from the licensing agreement of the patent rights. Cannabix Technologies still has rights to the patent and can use the technology covered by the patent to continue to develop, test and market a device.
These are my words, my interpretation. Take them for what you will.
