Thanks for finding that patent. Looks like it was begun in 2003, and was meant to automatically release the 2 front lines, and allow the 2 back lines to act as the "safety" system. He must have thought that the future of kite safety systems would be based on the system that Flysurfer used, where the 2 back lines "super-stall" the kite, and the kite backs down into the water.
A lot of people were trying to invent a way of dealing with the problems that plagued the releasable snap shackle, in those days.
I like the way he referenced the KF thread by Rick I...."Warning to Snap Shackle Users"...viewtopic.php?f=1&t=5202&start=0
