I've talked about patents in previous posts, so some of this is repeated.
You misunderstand how companies go after patents (not just HNSS). First, they are expensive to get and there are ongoing costs (fees) to maintain them, so companies wait as long as they can, and cram as much as possible into each one. Second, they are an after-the-fact item. Once an idea is made public you have one year to apply for a patent. Your date of invention is protected by the witnessed disclosure paperwork you need to keep on each idea.
The practical up-shot of all this is that you won't see anything published about the machine, no pictures, etc. until it is made public at launch. You also won't find any applications for patent until several months after launch.
Just part of the way the patent "game" is played.
