I don’t remember BKYI putting any of those patents (or the technology itself) to any use.
BKYI took a chunk of money from the Chinese, then used a portion of it to “buy” the rights to patents and software from the same group in China, in order to keep the balance for themselves.
The transaction was about getting a few million dollars from Chinese.
Basically, if I need $10, you give me $20 for a ton of equity, then I “buy” something for $10 that neither you nor I have any use for. Now I have $10, and you have the controlling shares of stock.
