Lawyer Rankings

United States > Intellectual property > Trade secrets (litigation and non-contentious matters)

Winston & Strawn LLP‘s team is ‘experienced‘, ‘transparent‘ and ‘hardworking‘. John Keville works form the Houston office and has a strong background in mechanical engineering, while Steven Grimes operates out of Chicago and is strong in cross-border matters. Keville recently acted for M-I in a trade secret misappropriation case against two former employees and its competitor Q’Max concerning oil and gas exploration technology.

United States > Media, technology and telecoms > Cyber law (including data privacy and data protection)

Winston & Strawn LLP is jointly headed by Sheryl Falk in Houston and Steven Grimes, who splits between Chicago and Hong Kong. The practice specializes in privacy assessment, audits and compliance programs, IoT, cloud computing and outsourced technologies, internal forensic investigations, incident response and breach notification, theft of confidential information and trade secrets, data security class action litigation, cross-border data protection and transfer and GDPR compliance. The client portfolio includes companies from healthcare, financial services and telecoms. Robert Newman and Monique Bhargava moved to Loeb & Loeb LLP in May 2018.

United States > Dispute resolution > Corporate investigations and white-collar criminal defense

Winston & Strawn LLP is noted for the ‘effectiveness‘ of its team ‘in dealing with all aspects of exceptionally complex matters‘. The group’s Washington DC office was greatly boosted in 2018 by the arrival of a team from Norton Rose Fulbright US LLP, including Abbe Lowell, Michael Loesch and Christopher Man, as well as Eric Meiring, who joined the group from the DOJ’s Criminal Section. Lowell is noted for handling top-drawer individual representations; recently he has advised Jared Kushner on the congressional and special counsel inquiries into Russian interference in the 2016 presidential election. ‘Bright and sophisticated in her approach‘, New York-based Suzanne Jaffe Bloom defended AIG in an FCA case before the Second Circuit, successfully dismissing a qui tam relator’s complaint with prejudice. On account of his ‘honesty, integrity and perseverance‘, Thomas Buchanan is described by one client as ‘an Abraham Lincoln of the modern era‘; he represented Transport Logistics International in a DOJ FCPA investigation into a kickback scheme involving Russian officials, leading to a deferred prosecution agreement and a drastically reduced fine. Chicago’s Dan Webb is representing Ukrainian businessman Dmitry Firtash in an FCPA case pending in the Northern District of Illinois. Other key practitioners include San Francisco’s Robb Adkins and New York’s Seth Farber, who jointly chair the group alongside Lowell. ‘Top-of-the-market‘ Tom Melsheimer in Dallas and ‘accessible‘ Steven Grimes (who splits his time between Chicago and Hong Kong) are also recommended.

United States > Dispute resolution > E-discovery

Winston & Strawn LLP‘s group of attorneys and technologists provides ‘a seamless, cost-effective service‘ that limits the need for outside vendors. It is often called upon to co-ordinate e-discovery for clients facing litigation across multiple jurisdictions, as well as to advise government agencies on a variety of issues. It is chaired by ‘terrific‘ John Rosenthal in Washington DC, who ‘knows his stuff inside-out‘. Also recommended is Houston-based Sheryl Falk, who leads the firm’s global privacy and data security task force alongside Steven Grimes in Chicago.
