They may be lodging a patent application , but they are not lodging an international patent , those are two very different animals .
A long process from patent application until a patent has been approved
Interesting technology with filtration that RWD hopes to use for extracting the potassium salt instead of floatation , be great to know how they intend to do it at an industrial level , also port access availability at Port headland is that an issue ?
