Not pharma, but sometimes where Google doesn't act fast enough, some companies have decided to apply a scorched-earth policy by using a very large amount of DMCA requests.

This is especially true with several companies fighting the trade in fake goods. Check Google results for "Louboutin", where you can see that very many results have been deleted from every page of the SERP; many thousands of deleted results in all.
