The Wall Street Journal is reporting that mobile location company Skyhook Wireless is suing Google, alleging that the search giant “interfered with a contract, announced in April, to put its location technology on Motorola Inc. phones.” Skyhook, for those not familiar, is a company that created a system — call XPS — that uses GPS, cellular, and Wi-Fi data to help triangulate the location of a device quickly. The company’s technologies were in previous iterations of iOS and currently are in dozens of mobile devices. The WSJ writes, “Google called Motorola several times to put “stop ship” orders on products containing Skyhook technology and insisted that its own location technology run side-by-side on devices using Skyhook. The result, the complaint states, is that Motorola shipped a device in mid-July without Skyhook technology.” Skyhook says the sour deal cost the company tens of millions of dollars; Motorola has yet to comment on the report.
