Anne McClain Sidrys is a litigation partner in Chicago. She is a Certified Public Accountant and, prior to law school, worked for five years as an auditor for Deloitte, Haskins & Sells (now Deloitte & Touche). In her 30 plus years at Kirkland, Anne has focused her practice on financial and complex commercial litigation, and has handled a number of disputes involving breach of contract, product liability, fraud, non-compete agreements and trade secret violations.

Anne has successfully tried a number of cases and has handled various arbitrations and mediations. By way of example, Anne tried a case for Motorola in the Southern District of New York where the plaintiffs sought $3.8 billion of fraudulent transfer and preference claims. Motorola won the lawsuit and the plaintiffs were not awarded any damages. She has also tried and arbitrated various matters for IBM, including a breach of contract/fraud case where the plaintiff sought over $360 million from IBM. In that matter, the plaintiff was not awarded any damages and IBM was awarded its entire counterclaim in excess of $20 million. Most recently, Anne tried a products liability case for 3M, which resulted in a complete defense verdict for 3M. Each of Anne’s trials and arbitrations have resulted in complete victories for her clients.

Anne was featured in the November 2015 National Law Journal “Winning” contest for her work on the IBM/Carlson trial. She was also featured in the “Big Suits” article in The American Lawyer for her work in the Motorola/Iridium bankruptcy matter. She was named as a 2012 BTI Client Service Super All-Star and as a favorite litigator by the BTI Consulting Group in its 2012 Client Service All-Stars report. In 2014, Law360 featured Anne in the article “Female Powerbrokers Q&A,” for her work in litigation. Anne was also named to Benchmark Litigation’s “Top 250 Women in Litigation” list from 2014–2023 and as a “Litigation Star” from 2014–2024. Anne was recognized as one of two “favorite outside counsel” in commercial litigation by IBM’s then General Counsel in The Wall Street Journal. In 2018, Crain's Chicago Business named Anne to its second annual list of “Chicago's Notable Women Lawyers.” Anne has also been recognized in Lawdragon’s 500 Leading Lawyers list and Law Bulletin Media’s Leading Lawyers. In 2023 and 2024, Anne was recognized by Best Lawyers® for her work in commercial litigation.
