DEFINITION

Classification: 264/465

Utilizing electrostatic charge, field, or force (e.g., pinning, etc.):

(under subclass 464) Processes wherein the energy used is static electrical or a force or field created thereby.

(1) Note. Electrostatic energy is considered to be a form of electrical energy which has the capability of attracting and holding small particles having an opposite electrical charge.

(2) Note. An electrostatic charge is an electric charge stored in a capacitor or on the surface of an insulated object.

(3) Note. An electrostatic field is considered to be the vector force field set up in the vicinity of nonmoving electrical charges.
