Let's do something highly unusual.
Let's think things out.
According to one chess board master, "We All Win!".
So let's say "We All" includes you, as a biochemistry researcher.
You just discovered an isolatable strand of DNA that allows people to think rationally.
You know you cannot patent it.
And besides Madison Avenue (Mad Men) would oppose it.
So what do you do?
1) Keep it a trade secret.
2) Write up secret private contracts which allow only a select few Illuminati persons to take the Limitless pill. The rest of humanity remains dumb as dipped pith. But hey they deserve it. Cause they're sure they win, they win! --By killing patents directed to genetic discoveries.
