DEFINITION

Classification: 361/212

DISCHARGING OR PREVENTING ACCUMULATION OF ELECTRIC CHARGE (E.G., STATIC ELECTRICITY):

(under the class definition) Subject matter relating to the dissipation of any residual electric charge present on or in an object or material.

(1) Note. Where the discharge of the static electricity is combined with the specific features of the art environment, the search should extend to the class which relates to the art environment.
