Jeffrey Patt represents clients in a wide range of domestic and international mergers and acquisitions and joint ventures, as well as capital raising, corporate governance and general corporate matters. His mergers and acquisitions practice has spanned a variety of public and private transactions. He has represented financial and strategic buyers and sellers in industries that include information technology and business services, software, insurance and financial services, health care, clean energy technology, and manufacturing. Jeffrey has served as special committee counsel in a number of going-private and affiliate transactions and he has represented management teams and executives in leveraged buyout transactions, spin-offs and bankruptcy sales.

Jeffrey frequently represents entrepreneurs and high-growth companies in raising capital. He also represents institutional, venture capital and strategic investors in their investments in public and private issuers. This work ranges from early-stage venture capital transactions to mezzanine financings with equity features to private investments in public entities.

A former lead articles editor for The Chicago-Kent Law Review, Jeffrey currently serves on the publication’s alumni board. He is also an adjunct professor at Chicago-Kent College of Law, where he teaches a mergers and acquisitions class as part of the LLM program in International and Comparative Law.

According to Chambers USA, clients say Jeffrey “finds pragmatic solutions to complex problems and convinces the other side that is the right approach.” He has spoken at client and industry conferences and seminars on topics ranging from fiduciary duty and structuring considerations in mergers and acquisitions to incenting and retaining management and key employees and legal aspects of initial public offerings. He contributes regularly to firm client advisories on mergers and acquisitions and corporate governance topics, including advisories on shareholder proxy access, shareholder voting rights and pre-merger notification reporting. In 2011, Jeffrey co-authored a book on stockholders’ agreements.
