DEFINITION

Classification: 117/50

Liquefying by energy from an electromagnetic wave or electromagnetic particle or arc or plasma (e.g., radiant heat):

(under subclass 49) Subject matter in which the energy to liquefy is at least in part provided by electromagnetic wave or electromagnetic particle or arc or plasma (e.g., radiant energy, electric current (e.g., Peltier* effect), laser beam, RF induction, electron beam, electric discharge).

(1) Note. It is not enough for this and indented subclasses that the process uses such energy source to initiate the process; the energy must be supplied concurrent with the growth process.
