Patents & Marks
Our engineering is on the record. Granted patents, pending applications, and registered trademarks cover our solventless separation equipment and processes.
United States Patents
Granted: United States & International
Solventless resin extraction technology
United States: granted. Multi-plate press systems and directional-flow method for mechanical resin separation.
Press technology
United States: granted. Programmable-force pressing apparatus and heated-platen control.
Separation equipment
Europe: granted. Mechanical separation apparatus and optimized flow geometry.
Process technology
Pending, international phase. Flow-control extraction system: process and apparatus for scalable mechanical separation.
The directional-flow geometry in these patents also shortens the rosin’s path off the heat and into a seated collection cylinder, an emergent quality benefit of the design, not a claim of the patents themselves. The science of the collection path →
The parchment cone and folded-pouch geometry are likewise described in these granted patents (US 11,040,510 / 11,511,465) as components of the press system. See the parchment write-up →
Patent-Pending Technologies
Filed: In Examination
- Improved extraction bag geometry (V3.7): U.S. application pending. The fold-over-bottom, side-seam-only, flapless, directional-channel design is engineered to keep flow channels open under load; see the flow-control write-up.
- Smart agitation water separation system: U.S. application pending.
