Of course you can sell technology with or without 1) a patent application or 2) a patent embracing that technology...trade secrets or other confidential info is an example.
But ask yourself...trade secrets can be reverse-engineered and duplicated by any competitor....Coke formula is the exception to that concept I know of...complete formula is still locked in a safe somewhere, and a very few employees know only parts of the formula.
When the patent is filed and published that IP cannot enter the Trade Secret road anymore. At the best the making of the Bavituximab molecule (which if I remember well is NOT the mandatory example given in the patent but is covered by the generic claims) could remain a trade secret.
However, I think (to be verified) that the FDA has disclosure rules after 10 years. Not sure when those 10 years start. But with PPHM producing Bavituximab in Avid I doubt that know-how spreading techniques like the ones you sited for Coca Cola Beverage Company can still be put in place.
But yes, PPHM could transfer the right of the Alan Scrout et All patent if UTSW terms (probably inside an EDGAR CTO) do not prevent it.
On a side note, I think Gillette is another example of a trade secret that has not been broken. Neither Wilkinson (Gillette's biggest competitor) nor the complete Chinese market that jumped on raser blade manufacturing produces anything near Gillette's Quality. I bought 10 different packs via AliExpress and all weren't near as sharp as Gillette's however at 10% of Gillette's price.
Furthermore both are a good illustration that new technology does not always place older technology in the same field outside the market. Gillette is still there with its blades never the less the electric razer revolution. And it comes again, IMO, back to the sharpness and the resulting clean shave you get with Gillette blades.
So Immuno did not flush away Chemo/Radio, even after 100 years and Nobel Prices in the field such as for Jules Bordet, however with CAR-T there seems to be an opening. PPHM should nicely fit in there.

Peregrine Pharmaceuticals the Microsoft of Biotechnology! All In My Opinion. I am not advising anything, nor accusing anyone.
