DEFINITION

Classification: 204/157.41

Using laser:

(under subclass 157.4) Subject matter wherein the chemical reaction is claimed or solely disclosed as being induced by the use of light amplified by stimulated emissions of radiation, i.e., a laser.

SEE OR SEARCH THIS CLASS, SUBCLASS:

158.2, for processes of purifying an inorganic substance by employing a laser to decompose the organic or inorganic contaminant.

(1) Note. This area provides for a specific wave energy process, i.e., laser. In order for a wave energy process to be classified herein as an original, there must be a claim to the noted process or the total disclosure in the patent must be directed to the specific process. The wave energy process in the claim specifically recited the process of this subclass. Processes not claimed or solely disclosed are classified below on some other aspect.
