Once upon a time, SLRW (formerly HydroFlo) possessed 19 patents. However, they were all worthless. If they had any value, the crooks running the show would have sold them off. Beyond that, in litigation back in 2010 or 2011, Dennis Mast, the original founder and CEO of HydroFlo (he was cited by the SEC in 2005 for 14 counts of fraud and was forced to step down from HYRF) sued for the patent rights as he had invented all of the patented junk). Mast was awarded 12 of them. Since then, most of the patents have expired because no one paid for renewal. Why not? They are worthless.
To answer your question, the shares you may hold are worthless. It's over for this scam.
