So no problem there. I always contact patent holders to inquire how they feel about me implementing their variants. I did the same for Falcon Chess, and also there it was no problem. I feel that I owe this to the inventors out of respect for their intellectual property. Even in cases where I would not strictly need their permission by legal standards, because the patent does not cover my part of the world, or because they failed to pay their patent fees.
