Jeffery Stec is a managing director, leader of Berkeley Research Group's IP practice, and co-leader of its economics and damages community. He has worked extensively over the past 20 years in the areas of antitrust, finance, intellectual property and survey research, as both a consulting expert and an expert witness.
In the area of intellectual property, Dr Stec has conducted economic and econometric analyses to determine the value of intellectual property and the amount of economic damages resulting from patent, trademark, trade secret or copyright infringement. He has addressed economic issues such as the appropriate measurement of revenues associated with the use of the infringing intellectual property, the portion of those revenues that can be attributed to the intellectual property, and whether the apportionment can be regarded as reasonable. He has evaluated economic and survey research issues in the context of Section 337 investigations conducted by the US International Trade Commission (ITC). He has evaluated the effects of anticompetitive conduct as it relates to the use of intellectual property.
In the area of survey research, Dr Stec has both created and critically evaluated surveys in the context of antitrust and IP engagements. He has developed complex sample designs, designed survey questionnaires, and collected and analysed survey data, including the derivation of complex variance estimates using simulation methods. He has conducted surveys that have been used to determine consumers’ perceptions and actions in the marketplace. He has also examined how products are used in the marketplace and how consumers value product features.
Dr Stec has presented his research at the annual meetings of the American Statistical Association, American Association of Public Opinion Research, Midwest Association of Public Opinion Research, as well as other academic and trade association conferences. He has also published articles and book chapters on IP-related topics, including topics dealing with patents. Dr Stec has testified in district courts, state courts, arbitration forums and at the Copyright Royalty Board, PTAB, TTAB and the ITC.
