The present invention relates to a method of obtaining value from providing fabrication equipment comprising the following steps. Fabrication equipment is provided to an article producer, which equipment includes an on-line analyzer for detecting the presence of a tracer element. Raw material which contains the proprietary tracer element is then provided to the article producer. The article producer is then allowed to begin to convert the raw material to a finished article using the fabrication equipment. The raw material is analyzed for the presence of the tracer element while the fabrication equipment is operated. Appropriate action, such as charging a royalty or shutting down the fabrication equipment, is then taken in the event the tracer element is not detected.
