In late 2017, the PRW patent was deemed allowable by the US Patent and Trademark Office. After close examination of the allowed patent claims, we decided to add four new claims which provide broader protection for the invention and greater design flexibility. We anticipate getting final approval later this year. With the broader claims, the entirety of the PRW technology will be protected under US patent law.
We are looking forward improving water quality and aquatic habitats throughout the country in the near future.
I'm sure the fish are looking forward to that too!
