Earlier quoted context omitted.
Getting a patent for something isn't necessarily a bad thing in and of itself. Doing harm with those patents is. Many companies get patents to protect themselves from situations just like this one.
When companies must have patents to defend themselves against patent trolls, the only possible winners are lawyers. Software patents are completely wrong. As a side note, pg said that if software patents are wrong, then all patents are wrong. BTW I'm confident that most of current IP environment (both patents and copyright) hurts people and the economy.
Software patents are being used as a way of buying monopolies over generic ideas, not particular but broad methods so the powerful could destroy competition, without exposing the proprietary code(not giving the knowledge at all).
The companies that grew and become powerful and rich without patents like MS and Apple want to use this money to buy them eternal prosperity against new comers.
As Dr.Friedman said, the same companies that rise with free market want the free market destroyed. The same person that as a little guy opposed software patents as the boss of a big company tries to enforce it: "If people had understood how patents would be granted when most of today's ideas were invented, and had taken out patents, the industry would be at a complete standstill today."
