Techcrunch did an interview with Kent Walker, Google’s Senior Vice President & General Counsel about patents. Some quotes
A patent isn’t innovation. It’s the right to block someone else from innovating.
An average patent examiner gets 15 to 20 hours per patent to see if it’s valid. It can take years to go back and correct mistakes. It has become a kind of lottery.
Patents are government-granted monopolies. We have them to reward innovation, but that’s not happening here.
