There was a lot of posturing and complaining by pharmaceutical companies in the U.S. and the U.S. Government tried to heavy the Indian Government, but to no avail.
When it became apparent that the Indians weren't going to budge, and with a growing realisation that other nations would ether do the same thing or import their drugs from India, the companies agreed to drastically reduce their prices on "humanitarian" grounds. Now they still make massive profits, just they are less massive than they once were.
This is now happening with academic research.
Nobody will shed any tears because greedy multinationals make a lower profit to ensure less people die from disease. Nobody will weep over Elsevier's reduced earning if it frees up necessary information and research findings so science can progress for the benefit of all mankind.
The entrenched interests of rich, arrogant corporate executives and business owners in first world nations are finally being disrupted by poorer nations who don't care about this group of people. But that's what happens when you gain an attitude on I weaning entitlement - you eventually overreach so far you come undone, and nobody feels any sympathy when it happens.
This not to mention all the extra capital needed to fund research into all of the drugs that never make it to market before a company finds something that works.
It's a pretty gross abuse of the original idea of patents.
Now, figure out what the correct dose is, how to get it into a mammal so that it's not metabolized into uselessness, how much you can safely give the mammal.
Now, start again with humans and hope you don't get to the final stage only to find out that it's not as effective as existing treatments or has side effects that will open you up to lawsuits.
Finally, once you've done all that, scale out the production of your compound such that you can prove that every dose meets FDA quality requirements.
