It's completely understandable why Uber would want to patent its surge pricing algorithm. However, the mere existence of surge pricing (especially prices that are 2-3x+ the normal rates) will allow for further innovation in the ride-sharing space. Expect to see more emphasis on 'ride-share pooling' and even on scheduled rides. Consumers will also become smarter as they are given tools and data (like whatsthefare) that help them better plan out their trips to avoid the price gouging. Extreme surge-pricing will be less prevalent as consumers get smarter and as competitors better forecast and communicate demand spikes more rapidly to their drivers.
