TUALATIN, OR  -  SawStop says it filed complaints at the U.S. International Trade Commission and the U.S. District Court in Oregon against Robert Bosch GmbH of Germany and its U.S. subsidiary Robert Bosch Tool Corporation to stop what it sees as infringement of SawStop’s patented inventions, and incorporated the following statement:

After years of denying the need for active injury mitigation technology on table saws, Bosch has announced that it intends to release a table saw that incorporates numerous inventions developed and patented by SawStop. As part of the lawsuit, SawStop is asking the ITC to exclude Bosch’s infringing table saws from entry into the United States, and to order Bosch to stop advertising and selling infringing products in the United States.
“SawStop has invested millions of dollars developing inventions to protect woodworkers from serious injury,” said Dr. Stephen Gass, SawStop’s President, “and those inventions have been awarded patents. Patents are the cornerstone of American innovation, protecting the work of inventors from unauthorized use.  A foreign corporation like Bosch, who takes advantage of the American patent system by filing multiple patent applications every day, should respect the patents awarded to others instead of relying on its size and financial resources to disregard those patents.”
 “We are proud of the difference our table saws have made in the lives of woodworkers,” said Dr. Gass. “SawStop saws have already saved thousands of woodworkers from serious injury. And although Bosch is one of the world’s largest companies with billions of dollars in annual revenue, we will vigorously defend our patent rights.”

SawStop is the world leader in table saw safety. Each SawStop saw stops and retracts the blade on contact with skin. The company’s saws are designed to minimize saw-related injuries and the costs associated with them.

Bosch announced in March 2015 it would bring the Reaxx jobsite saw to market in Fall 2015. It uses flash-sensing technology to detect whether the operator's finger has made contact with the blade, then shuts down. After activation, the system can be reset in less

than 60 seconds. Operating along the lines of an airbag, Reaxx employs a two-shot cartridge that enables activation for two incidents before replacement is needed. Once the stopping mechanism is triggered, the operator rotates the activation cartridge and reset the drop mechanism

and the Reaxx table saw will resume operation. Parts, instructions and wrenches are located onboard the saw, including storage for extra activation cartridges. This aspect of its operation differs from the SawStop braking mechanism, which mechanically contrains the blade in a manner that requires both blade and stopping mechanism to be replaced.

SawStop, which has been manufacturing the only blade-stopping saw technology on the market, introduced its jobsite version of its saw in March 2015, with Rockler and Woodcraft picking up distribution.

SawStop's cabinet and other table saw models are well-regarded by woodworkers. The category of saw safety has also generated, litigation and the interest of regulators. The Consumer Products Safety Commission has been considering saw safety operational rules that seem to suggest SawStop-type safety technology could be required when and if they are issued. 

In February 2014, SawStop's parent, SD3, filed an antitrust suit against Black & Decker, Ryobi, Hitachi, Bosch and other saw makers, claiming the saw manufacturers conspired against adopting SawStop safety technology. But a federal court dismissed that claim in August 2014.
