Our Patents

A patent needs to demonstrate to the patent examiner something that is new, useful and is not-obvious. We filed our first provisional application with the US patent office in 2002. Our focus was on making inventive steps to restoring pipes in-place. That inventive spirit leading to useful application of a technology is in part who we are, striving to make your life better.

Today, we have been awarded over 40 US and International patents for what we call the ePIPE Process. The patents cover things like how we seal leaks in pipes, prepare the pipe and how we help protect your health by reducing lead and copper from leaching from the pipe into your water.

Even after being awarded over 40 patents our efforts to improve what we do for you continues with active research and patents pending. Our ePIPE patents and  patents pending provide distinct improvements over other similar technologies.
