Advanced Light Technologies filed for this patent in 2001, for a medical, agricultural, and industrial application to cover the process of identifying and exploiting differential absorption.

Quoting from the IPEA report: "Claims 1-19 meet the criteria set out in PCT Article 33(2)-(3), because the prior art does not teach or fairly suggest the steps of identifying the heat capacity of the target and of the host in a combination of steps of selectively exciting a target in a host by exposure to electromagnetic radiation that is differentially absorbed. Claims 1-19 meet the criteria set out in PCT Article 33(4), and thus have industrial applicability because the subject matter claimed can be made or used in industry."
