U.S. federal trademark · Serial No. 90813240
The device is a unique "liquid plant" comprised of Spirulina cultures growing in a series of small tubes that emulates a real life plant. Just like a normal plant, it is photosynthetic; it "grows", fixes CO2 and releases O2. It also needs to be cared for. In this case, its growth medium needs replenishing from time to time
