Generate text that refutes this claim: The current patent system is unjust and creates perverse incentives that benefit large pharmaceutical companies at the expense of ordinary citizens  The current drug patent regime is largely designed to benefit and shield the profits of large pharmaceutical companies. This is due to the fact that most of the laws on drug patents were written by lobbyists and voted upon by politicians in the pay of those firms. The pharmaceutical industry is simply massive and has one of the most powerful lobbies in most democratic states, particularly the United States. The laws are orchestrated to contain special loopholes, which these firms can exploit in order to maximize profits at the expense of the taxpayer and of justice. For example, through a process called "evergreening", drug firms essentially re-patent drugs when they near expiration by patenting certain compounds or variations of the drug1. This can extend the life of some patents indefinitely ensuring firms can milk customers at monopoly prices long after any possible costs of research or discovery are recouped. A harm that arises from this is the enervating effect that patents can generate in firms. When the incentive is to simply rest on one's patents, waiting for them to expire before doing anything else, societal progress is slowed. In the absence of such patents, firms are necessarily forced to keep innovating to stay ahead, to keep looking for profitable products and ideas. The free flow of ideas generated by the abolition of drug patents will invigorate economic dynamism.  1 Faunce, Thomas. 2004. "The Awful Truth About Evergreening". The Age. Available:

There is nothing unjust about the patent system. It protects everyone equally. The nature of democracy is such that people are allowed to express their opinions and to organize to further certain aims. Drug companies have a particular interest in protecting their patent rights so it is only natural that they should involve themselves in the process of how those patents should be treated legally. They are not miscreants, but rather are participants in a system that is designed to be as fair as possible for everyone.
