What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12587124B2 for a high power battery-powered system to Milwaukee Electric Tool Corporation. The patent, filed on December 2, 2019, details an electrical combination, a tool system, an electric motor with specific power output (at least 2760 watts) and diameter (up to 80mm), and a battery pack with a volume up to 5.2x10^6 mm^3 and a nominal voltage up to 80 volts. The system includes a controller to manage current transfer between the battery pack and the tool.

This patent grant signifies a new intellectual property asset for Milwaukee Electric Tool Corporation, potentially impacting competitors in the power tool and battery system markets. While this is a patent grant and not a regulatory rule, it establishes exclusive rights for the assignee. Companies operating in this space should be aware of this granted patent and its claims, particularly concerning the specified power, voltage, and size parameters for battery-powered tools and systems.

Abstract

An electrical combination, a tool system, an electric motor, a battery pack, and operating and manufacturing methods. The tool may include a tool housing, a motor supported by the tool housing, the motor having a nominal outer diameter of up to about 80 millimeters (mm), the motor being operable to output at least about 2760 watts (W), and a tool terminal electrically connected to the motor; a battery pack including a pack housing defining a volume of the battery pack, the volume being up to about 5.2×106 cubic millimeters (mm3), battery cells supported by the pack housing, the battery cells being electrically connected and having a nominal voltage of up to about 80 volts (V), and a pack terminal electrically connectable to the tool terminal to transfer current between the battery pack and the tool; and a controller operable to control the transfer of current.
