DEFINITION

Classification: 204/157.4

Process of preparing desired inorganic material:

(under subclass 157.15) Subject matter wherein an element of inorganic compound is produced by a chemical reaction brought

about by wave energy.

(1) Note. An inorganic compound is one that does not meet the definition of "organic" as elaborated in subclass 157.6.
