I'm much more concerned about patenting then certification. You can certify devices all day long but what concerns me is this item isnt even "patent pending" it looks more like someone else owns the patent and HISC is acting like they own the product. While someone else owns the pantent most of the profits will go to them not this company. Isnt obtaining the patent more important then the certifications??? Yet they've been very secrative on saying anything about the patent itself. Without know the arrangement there is almost no way to assess how much profit the company actually makes on these units and how many would constitute a "profitable" sale. One thing i've learned about these stocks is if you ignore red flags and focus on the "positives" you get burnt. Mark this post. ;)
