I agree change is not coming in the political front. Lobbying power defending the patent status quo is enormous, and reviewing Patent Law isn't in any political agendas.

Big tech companies take advantage of the system. Microsoft has made billions of dollars out of licensing Android related patents, Apple applied for a paper bag patent recently and Google has "patent parties" when (as I have been told by Google friends) they encourage engineers to work with attorneys in filing patents on anything they worked on that could be patentable.
