So I show up at the ISC office in Monroeville, PA (though ISC now "InventHelp" is based in downtown Pittsburgh), with the billion-dollar idea YouTube. They explain to me, after I'm done disclosing it, that it doesn't seem worth a patent since there is no patentable stuff. They recommend I trademark it, but they won't provide any funding.
I went to a lot of places in hopes someone could give me some cold, hard cash to start the company: my friends, family, and about a dozen "company incubators" - VC or Angel funders, who are supposedly there to help you start a business, but they're real picky about who they help and how.
The ISC has this policy: after 3 years, they'll destroy any record of your discussion to "protect the idea" - I pointed out (at the time, and also a few months ago when I tried to get the information from them - but the guy who helped me that day is now retired and they won't contact him) - this doesn't actually protect the idea, or the inventor. So why do it? Had they kept a record, this would have protected the idea. Had they provided me with copies of their notes, this would have protected me. They do this, most likely, just to protect themselves.
