DEFINITION

Classification: 523/306

Utilizing energy potential described as obtained as waste or by-product from a prior or concurrent operation:

(under subclass 1) Process of treating or forming a desired or intentional composition utilizing energy potential described as obtained as waste or by-product from a prior or concurrent operation, e.g., energy cascading, etc.

(1) Note. Mere cascading of streams from vessel to vessel is not sufficient unless the intent is to capture otherwise waste energy potential. Intent will not be presumed but must be shown by the description in the patent claims.

(2) Note. The process herein should be with recovery or recycling of an unusual energy source thus specific intent is required.
