Inventors and entrepreneurs have vocations fueled by passion. Many would have done it for free or as a hobby if it hadn’t become a profession. Mark Rosenzweig is a natural creator, driven by his passion. This fuel has led Mark to develop his ideas into viable products and innovations that he has been patenting since 2003. From an innovative filter sensor and indicator for vacuum cleaners to a basket for deep fryer and methods of cooking food products to a compact cyclonic bagless vacuum cleaner. Sometimes independently and often as part of creative teams, Mark has patented just under one hundred innovative inventions between 2003 and 2017.
