Dual International Patent Certifications: Macro’s Core Technologies Lead Global Innovation in Kitchen and Bathroom Solutions

Recently, Macro secured two additional international patent certifications. The United States Patent and Trademark Office (USPTO) granted an invention patent for its core energy-storage heat-exchange technology, while the Japan Patent Office (JPO) awarded a utility model patent for its micro-nano bubble wellness technology. These two breakthrough achievements—driving an efficiency revolution in electric water heaters and elevating health standards in gas water heaters—not only demonstrate Macro’s leading R&D capabilities, but also position Chinese innovation as a new global benchmark in the kitchen and bathroom industry.

U.S. Patent Granted in Just 4 Months

Macro’s Living-Water Superconducting Technology Reshapes the Industry Landscape

The United States Patent and Trademark Office (USPTO) has officially granted Macro the invention patent for the “Control Method and Device for an Energy-Storage Heat-Exchange Electric Water Heater” (Patent No. US 12,442,562 B1). The patent was authorized in just about four months from the date of application—more than 85% faster than the U.S. average authorization period of 26.2 months—setting a new record for expedited approval in the industry and becoming a “benchmark case” in U.S. patent examination.

“Control Method and Device for an Energy-Storage Heat-Exchange Electric Water Heater” (Patent No. US 12,442,562 B1).

This technology represents a breakthrough for the electric water heater sector. By integrating the advantages of both instant and storage-type systems, it introduces an innovative open, non-pressurized water tank design combined with dual internal-external circulation heat-exchange architecture. This achieves three major advancements: significantly reduced volume, enhanced water purity, and sharply improved energy efficiency. It not only addresses long-standing industry challenges—such as water contamination in conventional electric heaters, low heat-exchange efficiency, and the inherent trade-off between storage capacity and water supply—but also delivers substantial improvements in spatial compatibility and cost efficiency, offering global users a more efficient and cleaner hot-water experience.

The rapid patent approval reflects the strong inventiveness of Macro’s technical solution and the precision of its intellectual property strategy. It accelerates the establishment of technological barriers in the U.S. market, secures an early strategic advantage for the global launch of energy-storage heat-exchange electric water heaters, and underscores the company’s forward-looking vision and professional capabilities in global IP deployment.
