Ah, I completely support your righteous anger against the tragicomedy of US "IP colonisation", though note that it has not much to do with my comment about the possibility of an open source patent.
The fact that most of the world was just laying down belly up to accept the negative consequences of the ridiculous cottage industry of churning out patents "for later" is truly enraging if someone gets to see how little value it produces. (It's very convenient for large conglomerates, VC fueled startups, and ... that's it.)
When it comes to specifics, ie. with pharma, it's hard to really disentangle the mess from other ugly facts, like the post-WWII global economy which and the very misregulated US healthcare industry (R&D including).
The US is subsidizing R&D for the world, because the other rich countries have sane "collective bargaining", but this leaves the small not so rich markets out in the fucking cold, because they have a weak bargaining position (market access doesn't worth that much to pharma companies) and also usually no internal R&D (so no local companies filing for these trivial parents). But because of all this in effect the world is buying R&D at the worst price!
(Though of course the picture is more complicated than this, but R&D is definitely waaay too inefficient in the US, but also all over the world too.)
