No updates on this from SM on his site, but for anyone interested in keeping up with the status of his application, it's all right here: http://portal.uspto.gov/pair/PublicPair Select Publication Number and enter: 2013-0233779 Looks like it's still marked Ready for Examination
Some results, for anyone who can decode this...I downloaded all of the lasted published documents resulting from the examination and bound them together in a single PDF. Not quite a clear as the PCT reviews.
Looks like he's got his patent, issue notification sent last week and it's on google http://www.google.com/patents/US20130233779 Patents aren't very easy to get so good for him, it's quite an accomplishment no matter who it is. I'm just surprised that he hasn't said anything about it. http://algaescrubber.net/forums/forumdisplay.php?23-Patents-Patent-Applications-and-Trademarks
