KAI Issues Brous Blades Cease & Desist Letter Over Sub-Framelock
Brous Blades announced it has received a Cease & Desist letter from KAI U.S.A. Ltd. defending its US Patent (no. 9,120,234) for the sub-framelock mechanism. The letter demands that Brous Blades immediately stop all manufacturing, use, import and sales of infringing products in the U.S., destroy all inventory, and pay a 10% royalty for past sales of Brous Blades products that include a sub-framelock.
The knife in question appears to be the Brous Blades XL Silent Soldier Flipper. In Brous Blades’ product literature for the XL Silent Soldier Flipper, the lock is described as “one of the most advanced sub-framelock designs on the market.”
In June, KAI U.S.A. Ltd. caused a stir in the knife community when it issued a similar Cease & Desist letter to Microtech. At the time, Microtech appeared to be the only company that was affected, which led some to speculate that bad blood between the two companies was behind the legal action. KAI subsequently told KnifeNews that it was strictly business, and all knives that were possible offenders would be examined on a case-by-case basis.
