This discussion provides a translation of the link you provided and some additional recordings of a guitar with his fretting system:

I did an internet search for a patent in his name but did not find anything. The translation suggests that he has "distributed" the required amount of saddle compensation proportionately across the frets by changing the position of the frets. In other words, no longer equal temperament, 12th root of 2.
He states that for existing guitars brought to him for intonation issues, he uses the system that was patented in the U.S. by Buzz Feiten.
People have been trying to tackle the issue of being in tune since at least the 1600's, and have tried a LOT of different methods. Lute makers and players tried all manner or schemes including bridge and nut compensation and various positioning of the tied, moveable frets. The best all-around compromise that has emerged still seems to be equal temperament. I'm open to improvement, but this doesn't seem to me to be an improvement.
