Go read the ptab filings guy, you are wrong and I know cannot deal with it.
The ptab filings show
1. Kidrin was not the developer as you say
2. He bought the company / acquired the patents via that purchase
3. The company does not develop any software - Mr Kidrin is the only full time employee, he is not a coder, they have no products that are marketable in any sense or commercialized
You are welcome to argue with me till you are blue in the face, anyone with common sense knows Worlds is a NPE sir.
If you want to argue an orange is blue, you can keep saying an orange is blue, it doesn't mean an orange is blue, sorry
