US Patent office invalidates previous validation of Apple multitouch patent, unless and until they validate it again

The United States Patent and Trademark Office (USPTO), which often seems content to grant patents willy-nilly and let companies fight out their validity in court, has just ruled that Apple's massive multi-touch patent is invalid. At least for now. They approved it before and may approve it again. But they're invalidating their previous validation unless and until they validate it again...
