That is the original voice search patent granted to Google, but not the one that we have been discussing. The one that we have been discussing is the child of the '987 patent to which you have linked. Like the child, the parent initially was rejected due to the teachings of Weber, but as with the child, the parent overcame those objections and rejections by modifying the claims, in the parent's case by modifying the manner in which the weighted boolean search is constructed.
