(under the class definition) Structures for protecting life and/or property from atmospheric electrical discharges, due to either a direct stroke or due to induction from the discharge.
(1) Note. For related subject matter in this class, see Search This Class, Subclass, below.
(2) Note. Where significant structure of the device protected is claimed, in addition to that necessary to define the lightning protective means, the classification is with the device, with a cross-reference here.
(3) Note. Art structures made of conductive and/or insulative materials are with the appropriate art, even though claimed to be for lightning protective purposes.
(4) Note. Collection of atmospheric electricity is elsewhere. See the Search Class notes below.
(5) Note. Protection of electrical equipment from electrical disturbances including over-voltage is with the appropriate art even though the disturbance is disclosed and claimed as due to lightning. See the Search Class notes below. SEE OR SEARCH THIS CLASS, SUBCLASS:
