MACH3 STABS QUATTRO - BUT CAN IT TWIST THE BLADE?

Just hours after Schick-Wilkinson Sword unveiled the first four-blade razor, Gillette filed a rapid-response patent infringement claim, claiming that the new Schick Quattro has infringed the Gillette Mach3’s technology.

The issue a Boston federal court will be asked to consider is whether Schick's synchronised four-blade configuration, which retails at $8.99, infringes the patents that allow the three Mach3 blades to extend progressively closer to the beard. Gillette, which dominates the worldwide razor market, seeks preliminary and permanent injunctions, triple damages and other relief. But its response is not confined to legal action: the main battle will take place in the open market: Gillette has announced three new shaving products of its own, including an update of its Venus system for women.
