Ferraiuoli Secures U.S. Patent for Innovative Water Purification System in the Shape of a Water Droplet
By Ferraiuoli LLC

The United States Patent and Trademark Office (USPTO) has granted Patent No. D1101899 for a Water Purification System in the Shape of a Water Droplet, marking a unique development in the field of water purification design. The patent was successfully prosecuted by the law firm Ferraiuoli on behalf of ATECOM LLC, underscoring both the design innovation and intellectual property strategy behind the technology.
A Novel Design with Practical Implication
This patent does not cover the internal workings or the functional mechanism of the purification system. Instead, it protects the ornamental design — specifically the droplet-shaped exterior form of the system — as the claimed subject of the design patent. According to the patent documentation, what is protected is the ornamental appearance of the system as shown in the drawings; interior details are indicated with broken lines and are not part of the claimed design.
Under U.S. patent law, this type of protection — a design patent — safeguards the unique visual appearance of a manufactured product. Unlike utility patents, which cover how an invention works, design patents protect how a product looks and can be a valuable tool to prevent competitors from marketing visually similar products that could confuse consumers.
