Many years ago, when we started the commercialization process, we applied for several patents. In particular, some of them were for producing energy from the Earth mantle.
However, with time we realized that it is impossible to patent the principle or the laws of nature.
With this understanding, we switched to the know-how protection mode. With time, we built the iron-clad system of internal IP, which is available to our business partners under the condition of a strict confidentiality.
