First of all, plenty of drug research and patents are actually done in order to develop variants that avoid other patents. Patents in the drug industry are mostly a parasite producing more patents. Secondly, plenty of research is publicly funded. The major philosophical error people make when asking why would people create anything in the absence of IP laws is believing that just because they created/invented something, they are owed something in return. Plenty of times, IP gets created, but there is no one to sell licensees to because no one wants it. The major historical error is believing forgetting that people created and invented stuff just fine before IP laws existed.
