If he is legitimately the creator, I'm curious what exactly the patent is and how he plans to enforce it...
Kenji is my business partner at DSPA (notice we both have the same logo?), and he
is the creator behind Air Sentinel. There is no "if" about it.
The FAA doesn't decide how it's created. RID is simply a set of rules mandated by Congress, hijacked by DHS and the FBI, and given to the FAA to enforce.
ASTM set the actual technical standards, and it was accepted by the FAA. It is then up to private industry to create the system(s) by which it is operated. Other people or organizations are more than welcome to set up their own set of technical RID standards and submit them to the FAA. But the required investment in time and money make that unlikely.
Let's use the speed limit as a comparison. Speed limits are set by government entities. But they have no say so in how data is gathered by officers (or civilians for that matter). Each type of radar gun and speed camera has its own patent, usually multiple patents. Those patents are licensed to other manufacturers by the patent holder. No one can use patented software or hardware w/o that license.
In this case, Kenji is the patent holder for this particular method of data gathering. If someone else were to patent a different system, then folks are welcome to license that system for their RID apps.
Kenji put this out because he didn't like the way RID was implemented. Having pilot location public knowledge is a very concerning issue. His app will only allow subscribers to see pilot location. And only qualified folks will have that subscription.
There is a certain set of data required in the packet RID transmits. But there is no legal mandate on what the apps collect. Kenji's system is the one in play at the moment. So app developers will have to license that from him.
So instead of attacking Kenji, who is trying to make RID work for the pilot's safety, you should appreciate what he's doing for this industry.
