Milwaukee Issued Revolutionary LITHIUM-ION Patent

MILWAUKEE, WI – Today, Milwaukee Electric Tool Corporation received a revolutionary patent on their cutting-edge LITHIUM-ION battery technology for cordless power tools.

The company’s patented LITHIUM-ION technology represents the new generation of cordless hand held power tools powered by battery packs capable of producing an average discharge current greater than or equal to approximately 20 amps. This patent protects the Milwaukee® brand’s newly introduced M12™ and M18™ LITHIUM-ION product lines as well as the industry’s first V28™ and V18™ LITHIUM-ION product lines. More efficient and environmentally friendly, the Milwaukee® LITHIUM-ION technology is the result of many years of development by the company’s engineers around the globe, representing a multi-million dollar investment by Milwaukee.

“This patent, along with other patents already issued to Milwaukee in the LITHIUM-ION field provide broad, valuable rights to Milwaukee in the use of LITHIUM-ION batteries in power tools”, says Steven Richman, President of Milwaukee Electric Tool Corporation. “The granting of this milestone patent confirms the long-stated position of Milwaukee® as having revolutionized the power tool industry as the leader in LITHIUM-ION technology for power tools.”

At the outset of the company’s ground-breaking work in LITHIUM-ION technology, Milwaukee filed numerous U.S. and international patent applications on many of its inventions in this field. This new patent follows upon a series of patents awarded to the company in LITHIUM-ION technology since 2005, when the company went first to market with its V28™ LITHIUM-ION power tools.

Additional patents directed to various aspects of its LITHIUM-ION technology including a power tool battery pack having battery cells with a combined nominal voltage of approximately 28-volts, prevention of brown-outs, a multi-chemistry battery charger and a multi-voltage LITHIUM-ION battery charger, have been granted by The U.S. Patent Office, as well as Patent Offices of other countries. A number of other patent applications are in the pipeline.

“We are proud of our leading role in LITHIUM-ION technology, bringing our commitment to intellectual innovation, vision, expertise and quality to pioneer the future of the power tool industry,” says Joseph Galli, CEO of TTi. “These patents and patent applications are valuable assets to TTi, and further demonstrate our continued commitment to innovative excellence,” says Horst J. Pudwill, Chairman of TTi.
