The other technologies can all be secured directly through patent applications. But applying on their website isn't as simple as it sounds. The first condition for observing the entire site is a direct payment of one million Federal coins into a certain account before the application form can be filled out. Of course, the form varies for journalists. The million Federal coins are nothing for those who could afford a car worth 1.2 billion Federal coins. Needless to say, Finn Lewis doesn't ask for this money for nothing.
Once you've seen it, if you don't buy it, you can choose to get a refund. Finn would refund it, and these people could easily find out who owns the Goddess of Light car factory, so posing as Finn to cheat them out of a million seems improbable.
