Meet Bill Cook

Bill Cook has over 35 years of legal experience in IP litigation, internal investigations, data security, and privacy counseling as a partner in some of the nation’s top law firms, including Reed Smith, McGuireWoods, and Winston & Strawn. He has provided data privacy and security counseling to a wide range of industry sectors.

He conducts internal corporate investigations involving industrial espionage, malware, ransomware, employee misconduct, computer intrusions, and the advanced persistent threat. As an intellectual property litigator, he handles cases involving trade secrets, copyrights, patents, “malvertising,” privacy rights, social media and unfair competition before federal and state courts and the FTC.

Cook has also served as a federal court-appointed trustee in an international call-sell operation brought by the FTC. He is currently on the U.S. Trustees Privacy Ombudsman Panel.

Internationally, Cook has worked with clients in Canada, the United Kingdom, France, Spain, Brussels, Germany, Italy, and Israel on ISO 27001, PIPEDA, and the EU General Data Protection Regulation (GDPR) on security compliance. His international investigations have also involved China, Japan, Russia, Bulgaria, Poland, and Saudi Arabia.

He also advises clients on export and import regulations and compliance with the Department of Commerce’s Export Administration Regulations and the State Department’s International Traffic in Arms requirements. He litigates export and import compliance matters, as well as new shipper review designations. He has handled white collar criminal matters for victims and defendants concerning industrial espionage, healthcare fraud, defense contracting fraud, mail fraud, and violations of U.S. export restrictions.

In 2016, Cook was asked by the U.S. Secret Service to serve on the Steering Committee of the Chicago Electronic Crimes Task Force. In that role, he helps advance the collaboration among law enforcement, academia, and the private sector that has been a hallmark of the U.S. Secret Service’s 39 electronic crimes task forces across the country.

Before entering private practice, Cook served as an assistant U.S. attorney in Chicago for 16 years, including 14 years in the Special Prosecutions Unit of that office. He has tried 85 cases as a prosecutor and in private practice. While with the Justice Department, he headed the Computer Fraud & Abuse Task Force in Chicago and served as the Counter-Terrorism and Counter-Espionage Coordinator in the Chicago U.S. Attorney’s Office. He gained in-depth experience with business continuity planning while acting as the Justice Department Liaison for planning to FEMA. In private practice, Cook counsels corporate clients on business continuity planning, using many of the strategies developed in the book he co-authored, “Critical Information Infrastructure Protection and the Law,” published by the National Research Council.

Cook has testified before the U.S. House Judiciary Committee, the FCC, and the National Science Foundation on internet law and liability. He taught internet and web law as an adjunct professor at the University of Illinois Law School, and was a guest lecturer on information security law and liability at Bell Laboratories, Harvard, Yale, Purdue, the University of Illinois, and the University of Salzburg.

Prior to his legal career, Cook served in the U.S. Army Infantry from 1968 to 1970. As an Airborne Ranger, he was deployed as a combat infantry platoon leader with the 25th Infantry Division in the Republic of South Vietnam. He was awarded a Combat Infantry Badge, three Bronze Stars, two Purple Hearts, two Army Commendation Medals and the Vietnamese Cross of Gallantry. Cook is a service-connected disabled veteran because of his experiences in combat in Vietnam.
