"Nadav holds multiple patents in areas of social mobile networking, machine learning, network algorithms, and sensor technologies. His work has been featured in both academic and popular press (Technology Review, Businessweek.com, Wall Street Journal, Wired UK, and The Associated Press, among others), and received awards of recognition (including Best and Distinguished Paper awards, Knight News Challenge, SXSW Accelerator, IPSN Extreme Sensing Competition, and three Google Research Awards)."
There is nothing wrong with patenting truly new, truly sensible solutions to actual problems, in my opinion. The problematic patents are the trivial ones that currently swamp the software industry.
Maybe it would be helpful to adapt the protection period (20 years, IIRC) to the rate of innovation in the industry?
The nature of reality as it applies to patent law is why I don't fault companies for acquiring lots of patents, but do fault them when they use those patents offensively. Google remains among the very few large tech companies I respect when it comes to patent actions.
Google acquires a lot of companies for their IP. Not so they can sue people for infringing on it, but so they can use it. The property rights create a legal structure that allows those kinds of transactions to happen. Like with any other property right, that's the value of a patent--giving people a "thing" in which they can transact, which they can book as an asset, etc. Ideally, a lawsuit only happens when things go sideways.
