Katten Muchin & Rosenman LLP has been named a Go-To Thought Leader in the Litigation category by the National Law Review. In 2022, authors Julie L. Gottshall, Janet R. Widmaier, Andrew J. Schuyler, Stacey D. Mckee Knight, Janella T. Gholian, and Michelle A. Gyves reached thousands of industry professionals with their coverage of the US Supreme Court’s reinstatement of the OSHA employer vaccine mandate. Their timely reporting on the Court’s ruling and other local regulations in place or in peril because of the ruling provided a valuable resource to legal and business professionals. 

The National Law Review names Katten as a Go-To Thought Leader for the firm’s coverage of Estate Planning & Taxes. The firm’s article, “2021 Biden Plan Estate Planning Advisory,” breaks down President Biden’s estate, gift and transfer tax plan and reviews what they mean for capital gains tax rates as well. Although estate law can be a layered area of practice, Katten’s content broke it down for our viewers in an organized and thorough manner.

Katten is a National Law Review Go-To Thought Leader for the firm’s thought leadership on the Coronavirus pandemic's impact on the aviation industry, specifically the government’s ongoing operation support for the airlines and aviation finance and leases.  Katten’s thought leadership in aviation addresses leases and financing and the insurance of aircraft assets during bankruptcies, as well as government regulation and oversight of the aviation industry including the Treasury Department’s payroll support for airline workers and special payments earmarked for the airline industry under the CARES Act. The following Katten attorney authors were notable aviation law contributors in 2020: Lisa A. ClarkTom Healey,  Stewart B. Herman, Timothy J. LynesBrett J. Seifarth, and Miran Vila.
