In a word, yes, but look at the language of what you quoted:
Recently, they issued a patent for the first commercially available free energy device in history.
They aren't saying it's the first such patent; I'm pretty sure it's not. They're saying it will (if all goes as they say) be the first such device. That's a given by virtue of the fact that none of the devices that have been patented actually made it to market and functioned as advertised. If the patent office issued a thousand more such patents (as they probably will, eventually), the above claim could still be made by the inventors.
