When Google first announced WiFi-based systems hot air balloon --Project Loon, presumably a lot of people came out of this first idea is crazy and full of whimsy company also tried to change the world. But now the company, a company called "Space Data Corporation" claims as early as ten years ago, it has successfully developed the technology, and the project has violated Google's proprietary trade secrets of some company belongs.

Earlier this week, court documents submitted to the District Court of Northern California, Space Data means that Google violated the company's two patents, one of which is through networking balloon (obtained in 1999) provides network connectivity, then another the process is terminated and the recovery of these balloons (obtained in 2001). Both the earlier patents than Google, but Google also holds related patents Project Loon technology, and insisted that there is no reference Space Data technology.

Currently Space Data has provided SkySat and SkySite two products, both balloon-based networks and Google Project Loon connection provided very similar. The system is not widely used, even though the company already holds FCC authorization to provide broadband in Alaska and the Gulf of Mexico service spectrum.
