Intellectual Property

Bill Black has conducted financial analysis and incremental profitability studies, created and validated financial models, evaluated damages claims, provided expert testimony and assisted counsel in a number of significant intellectual property matters throughout the United States. Key elements of one damage calculation included identification of fixed and variable costs in a job order manufacturing environment, and documentation of incremental profitability. Plaintiff was awarded substantially all the damages claimed. In another multi-million dollar matter, Black delivered expert testimony highlighting the analytical and conceptual errors in the opposing expertís presentation and successfully rebutting the claimed damages. Key errors included ignoring the availability of acceptable non-infringing substitutes, and assuming that all defendant sales would have been made by plaintiff (at a substantially higher price point).  Black has developed a structured methodology for evaluating likely intellectual property damages at an early stage, which is discussed here.
