U.S. Patent No. 9,981,203 B2 issued on May 29, 2018, entitled “Rapid drying extraction targeting oil resin plant extracts.” It was issued to applicant and inventor Ahmed Shuja of San Francisco, California. Ahmed Shuja is the co-founder of OGZ Holdings, a cannabis extraction research company, and lvl Analytics, a tech analytics startup; Dr. Shuja is a scientist heavily invested in the newly emerging cannabis space. The specification discloses extraction processes and methods of cannabis material, done through a specific process of pulsed electric field (PEF). PEF is short and intensive electric pulses that modifies the cellular membranes; in doing so, it more rapidly removes the targeted organic material from the plant improving the process over the prior art. Further, the process includes drying the cannabis plant material, as well performing fluid extraction.
Figure 3 of the drawings diagrams the claimed process.
The International Patent Classification are A61K (preparations for medical, dental or toilet purposes (i.e., medicinal preparations of undetermined constitution containing material from algae, lichens, fungi or plants, or derivatives thereof, e.g. traditional herbal medicines)), and B01D (separating solids from wet methods (i.e., evaporation, distillation, crystallisation, filtration, dust precipitation, gas cleaning, absorption, adsorption, or similar processes which are not concerned with, or limited to, separation)).
The cannabis extraction space is a growing area for patents and other IP. Please contact Yonaxis for more information on this subject, or on any information on the patent process.
