I agree!  I looked up who own Regeneron. It is not owned by gates.  The two owners own a lot of stock.  Gates may be involved in some other way, but he is not the owner.    From Wikipedia The company was founded by CEO Leonard Schleifer and scientist George Yancopoulos. They are reported to hold $1.3 billion and $900 million in company stock, respectively. Both are from Queens, New York.[21] Schleifer was formerly a professor of medicine at Weill Cornell Medical School. Yancopoulos was an assistant professor at Columbia University. Yancopoulos was involved in each drug's development.[21]  From Yahoo Stock News: Insiders own 23% of this company.  The next largest holders are the following institutions FMR, LLC at almost 12% and BlackRock at almost 9.36%, Vangaurd at 7.5%, Capital World investors at 6.63, State street Corp at 4.35,  Wellington management at 3.50%, Loomis Sayles & Company at 3.12, and a variety of others own more than 1% and less than 2%.    To find who owns Regeneron we would have to evaluate the ownership of each of these institutions.    For example, BlackRock only owns 6.55% of BlackRock.  The rest is owned by all of the investors that I listed as owning the highest stakes in Regeneron, Tamesek Holdings limited, B of A.  Various others own less than 3%  Check Yahoo stock news for the rest.    It would take a deep dive to look into the ownership of each.    I am guessing if I looked up the ownership of most publicly traded companies, especially in Biotech, I would find similar ownership.
