Better check out the TSA and that will lead you to IPT's.
It has little to do with HDO's commentary on NDA's. NDA's are going the other direction.
For modelling, the TSA dictates ownership as creation occurs. Patents and copyrights are very limited compared to TS's. The reasons center around the value of not allowing competition to use IP and TS. A competitive edge has great value. See how Buffett expresses it financially.* A TS lasts over 3 generations. This assigns value to the creations. Secondly, the filings establish who came first. Most filings are about 100% redacted as it turns out. Their enforcement is sweetest of all since the infringer never sees the basis of the infraction, only the court does since the discovery does not go beyond the redacted documentation for the infringer.
You may notice that you have never read much about TS and IP infringements in the financial industry. There's not much news in reading blanked out documents (redacted documents)
The world is different than you or HDO think it is regarding ideas, their modelling and develpment. Non disclosure and non compete stuff is just superficial compared to IP and TS which is what you have brought up. Financial organizations are highly compartmentalized for good reason. There are many walls between a unique creation and the day-to-day utility of corporate book, securitization, and the trading desks.
When someone who walks into an organization with things of value, the relationship is determined in ways that are not commonly used. Mostly the corporation is offering an invitation where it is clear that TS and IP are on the table. It is not something that is on the street so to speak.
*Durable competitive advantage. See recent tungsten three way with Isreali's and Chinese. Got plant up in 6 months from stratch.
