DEFINITION

Classification: 204/157.42

Using sonic of ultrasonic energy:

(under subclass 157.4) Subject matter wherein the chemical reaction is either claimed or solely disclosed as being induced or effected by the step of imparting rapid oscillation at a frequency of greater than 10 cycles per second.

(1) Note. Claims drawn merely to "sonic" energy or "ultrasonic energy" are presumed to meet the stated limitations and thus would be classified herein.

(2) Note. This area provides for a specific wave energy process, i.e., sonic or ultrasonic energy. 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 need not be limited to the provided specific process if the claim specifically recites the process of this subclass. Processes not claimed or solely disclosed are classified below on some other aspect.
