Very cool that you worked on it! I've found most, I think, of the patents. They are.... as has been hinted at in this thread, very difficult to parse through and (imo) don't actually reveal much, though I may just lack the expertise! That's why I was hoping to get some NLP folks to speculate!

Your point on dates is something I did want to call out - I wouldn't be asking this if it wasn't ancient history. I have no interest in doing anything sinister. Just trying to explore a fun part of Internet history. Any shot I could shoot you an email to chat?
