Intellectual Property

From principle to product,
ten patents form a protective net

PowerMOS filed US and EU patents in parallel from the very start of its PLC product line. Our own patents plus formal licenses cover controller signaling methods, string connection structures, address-code burning and bead packaging — choosing PowerMOS means choosing full IP protection too.

Coverage

Scope of protection and our customer commitment

Coverage

The complete power-line carrier application chain

The patents above cover the controller's signaling method, the string's connection structure, the address-code implantation technique, optical addressing on a two-wire basis, and the bead's package structure — any pixel-control application using power-line carrier falls within this patent net. All patents are also filed in China.

Customer commitment
