Reminds me of the fast Hartley transform that was patented by Stanford in 1987. the patent was dropped in 1995.
There are cases where a algorithm is patented, but it is still possible to have open-source implementations of it. One example is here: https://www.aanda.org/articles/aa/full_html/2018/08/aa32858-18/aa32858-18.ht... (ctrl-f "patent"). So maybe it's too early to give up hope. Cheers, Martin
