The spelling of the maker Jhoseph struck me, so I looked around and noticed the circled R symbol, ?, which indicates a registered trademark. The TM symbol is also used on the site, which indicates claims to trademark protection but not that it's been registered. So I checked the patent & trademark office database and found that there is indeed a filing for the mark GOLDCASTER, in June 2009, though it is not registered yet. It will be, once the owner files certain documents and pays certain fees, but at the moment, it's not registered, and it should not state otherwise (see the bottom where it claims it is registered). That's a no-no. I suppose it's remotely possible that it was filed as a California trademark, but they don't have a searchable database so I can't check easily. And who's the owner? One Joseph Pistone of Venice, CA. Not one of the guys listed on the goldcaster site. And it has not been assigned, at least as far as I can tell.
Not sure why I'm posting this, but just wanted to share. I'm a patent attorney, and I can't help but check these things out when I notice odd stuff. This one's a bit strange.
