Not that I like Pharma very much or want to defend patents pretty much, but this argumentation is pretty bad:
> 1. Pretty much all Pharma companies have significantly higher marketing than R&D budgets (that's not evil, but still proves a point).
It's not evil, but I fail to see which point it proves. That pharma firms do a lot of marketing compared to R&D is related to patents how? The same is probably true for many other industries.
> 2. They are also one of the most profitable industries, so doesn't seem like they really need patents.
Their profitability "is a clear sign that patents work", would a proponent of patents claim. If there were none, they would be not profitable because copied, so no incentives to innovate, blabla. We don't know what would happen in such a case, so there is no point to make here without further justification.
> 3. They research is mainly on the "diseases" of the rich. For example the amount of money they invest into researching a cure for Malaria pales compared to the research into something like diet pills
Again, this is true but I fail to see how this is related with patents. Do you think, that pharma firms would suddenly all become very altruistic and start researching Malaria and other "fringe" (sorry) diseases when you abolish patents?
> 4. They have been the main companies behind the push to extend patentability, who do you think are the main industry who are pushing ACTA?
Yes, but what point does it make? That the (big) firms in the industry believe that patents work? How does it make patents bad? You'll need more arguments to support your logic.
> 5. They are also the companies who are the main drivers behind the US government pushing draconian trade agreements, onto developing nations. Which often leaves the poor in these countries without access to cheap generics.
This shows rather that pharma firms go ruthlessly after money wherever they can, not that patents are bad.
> 6. They are extensively abusing the patent system, by creating perpetual patents, i.e. when a patent expires they apply for a new patent where some compound is slightly changed, the trick is you can't make the old patented medicine, without violating the new patent.
Right, but companies abusing the patent system does not necessarily imply that patents are bad in general, merely that the system needs some loopholes fixed.
> 7. They have been caught multiple times paying for favourable publications/studies.
So has the tobacco industry, the wine industry, the coffee industry, and the candy industry. It is related to patents how?
> 8. Their patents actually only start after FDA approval, so they possibly get 20+x years of patent time.[...]
Well, those firms would tell you that they get to use the patented drug for 20 years on the market, and not longer. After all, if the FDA takes 20 years to approve a drug, the patent would have been worthless. So, I can see why that was implemented. The problem with other countries filing later (and therefore prolonging protection) would be solved by "global patents" by a patent proponent, I guess.
I am not saying you are wrong, but these arguments did not convince me.
