In reference to the patent: US20090293169

So this is provisional every become a full patent? If so is it still active?


This is neither a provisional nor a patent. It is a patent application and its status is "Abandoned -- Failure to Respond to an Office Action" so it seems unlikely to ever become a full patent. You can check this for yourself by looking at the US Public Pair site and entering 20090293169 and selecting "Publication Number". From that site you can see all the communications between the inventor's agent and the examiner.
