Jeffrey Klenk focuses his practice on the application of economic theory to issues of antitrust, as well as to the analysis of damages stemming from commercial litigation matters.

Examples of antitrust work undertaken by Mr. Klenk include analysis of alleged price-fixing, tying and bundling arrangements, the use of conditional rebates, and resale price maintenance.

In the context of damages, he has analyzed reasonable royalties and lost profits in patent infringement matters, lost wages in employment disputes such as wrongful terminations, and public interest and remedy issues in Section 337 cases. He also has significant experience analyzing issues associated with class certification, particularly in the context of alleged price-fixing.

Mr. Klenk has offered expert analysis in forums including district courts and the Equal Employment Opportunity Commission (EEOC). Examples of the expert work undertaken by Mr. Klenk include analysis of damages stemming from an alleged breach of an express warranty, analysis of lost wages stemming from a constructive discharge, analysis of incentives created by civil forfeiture laws, and analysis of the effects of certificate of need laws on the purchase of medical devices. In many of these matters, he developed economic models, including the use of econometrics, to isolate the possible effects of the conduct at issue.

In addition to economic consulting, Mr. Klenk has extensive teaching experience, having taught dozens of online classes for Penn State University’s World Campus. These classes have included micro and macroeconomics, labor economics, and econometrics. He has served as an adjunct faculty member at George Washington University and Catholic University. He has written about both antitrust and damages issues in journals and in trade press. He has also spoken on these issues at a number of national panels.
