> I wonder, why don't large corporations join forces and lobby the government and congress for changes in patent rules and laws?
The story I usually hear is that there are two main groups of companies that are lobbying for changes to the patent law, but because of the different nature of their industries they have diverging goals for patent reform and have not been able to reach a compromise (thus the legislature is also unable to reach a compromise). On the one side are the consumer electronics and software companies, and on the other are the pharma and biotech companies.
