 Yeah. So the process is patented and the utilization of this rock to produce Portland cement is also patented. So another company would need to license or joint venture with us in order to make cement via this process. Wow. So essentially what you're saying is unless they can come up with a different method, this is going to be the standard way to make Portland cement, at least in places like California and other countries with stricter laws in the next 10 to 20 years.
