But IP may not matter to Uber, since the lingua franca in Silicon Valley and tech startups general is customer acquisition, and its grammar is frequency of use. Its revenue is based far more on utility and habit — full disclosure: I use it occasionally, and most of the time it works just fine — and not on any marketing understanding of brand loyalty. Its marketing tools are incessant discounts and, more broadly, surge pricing, which lets it vary pricing when and where its competitors can't (thereby maximizing its margin in high demand circumstances, while undercutting rivals when low demand allows it). It's not branding rocket science, but brutally smart and efficient, old-fashioned sharp elbows selling.
