WaterHealth International, Inc. (Dr. Ashok Gadgil’s UV WaterWorks™)


UV Waterworks™ Device

Dr. Ashok Gadgil, an inductee into the National Inventors Hall of Fame, is recognized for his UV Waterworks™ water disinfection device that has made drinking water safe for over 100 million people across four continents. Knobbe Martens partner Adeel Akhtar worked with Dr. Gadgil to secure the patent for his ground breaking water purification device.

The patent examination process for Dr. Gadgil’s UV Waterworks device presented many challenges, and was at first denied patentability. Unfazed by the Patent Office’s initial finding, Akhtar responded to the rejections to persuade the Patent Office to grant a patent for Dr. Gadgil’s invention. In a further reexamination proceeding, Akhtar encouraged Dr. Gadgil to accompany him to the Patent Office in Washington D.C. to explain, in-person, the far reaching potential of his revolutionary invention and to argue for its patentability. Dr. Gadgil’s sincerity and unwavering belief in the life changing capabilities of his invention, in conjunction with Akhtar’s skillful defense of the simple ingenuity of the water disinfection device, eventually swayed the examiner to confirm patentability for the inventions embodied in the UV Waterworks™ device.
