if the patent included the plans for the devices that make the invention happen and not just a fucking description of the invention, then it wouldn't be prior art.
but as usual for the patents nowadays, it doesn't actually describe how to build the AI for such a doll. it only describes what the doll could do.
patent office sleeping again. should not have been granted. also numerous other patents have done the same shit already, so this is more like "an idea previously described even in patents but IN A TEDDYBEARDDDD".
