And my original point was that Paul Buchheit's request that "If you know great scientists solving important problems, please encourage them to apply" was unrealistic. YC isn't going to get the crème de la crème of scientists or scientific innovations - they're getting what's discarded by the TTOs.
To be more precise, nobody's going to get the top scientists (they're going to go right back to their labs) and the biotech VCs are going to get the top innovations (for which they often have an informal licensing option with the inventing professor before the academic research even begins). There's a record amount of funding in biotech right now, but why spread it evenly? Might as well just run dozens of trials in parallel for therapies derived from a single technology.
Some Universities don't automatically claim ownership of any IP you create there.
Except for the minor problem that any IP generated through their work is owned by the university. And if the IP's valuable, it typically flows straight into the hands of Flagship, Polaris, Third Rock, & co. The professor might have a say in what happens to the IP, but the students and postdocs have zero leverage with the TTO. And how could they? They are replaceable cogs in the machine (and often in the US on a student/work visa) - Bob Langer is not.
