I applaud your DD. It's an agreement, a signed agreement. Was it ever formally submitted to the patent office? From what I see, the patent office contacts Advanomics regularly for missing payments. You can file whatever you want, doesn't mean it's law. To me, there is no proof Sunshine owns the patents, sorry.
I put an email into a reliable source, not Camille, the patent office. I'll forward you their response. Think they've had plenty of time to make the change.
Ask Camille, since he only replies to you, where the inflated price from 51k to 4mil is all about.
