Mayer Brown

Mayer Brown is recommended nationally for general patent litigation and Hatch-Waxman disputes for branded drug makers. In addition to the firm's contentious practice, the firm is also notable for its work in patent strategy, exemplified by its role as IP counsel for Bristol-Myers Squibb in its $74 billion acquisition of Celgene. The merger is the largest ever in the pharmaceutical industry.

Lisa Ferri, who co-chairs the firm's IP practice group, is described by a peer as someone who is "excellent" and "always impresses." Ferri is well known for her expertise as a patent litigator, but recently showcased her ability as strategic advisor through her role as lead IP attorney on the Bristol-Myers Squibb merger. She also acted for Sanofi in a patent dispute against Genentech and the Washington Research Foundation related to the client's cancer drug Elitek. Ferri was shortlisted for the New York Patent Strategy & Management Attorney of the Year award by LMG Life Sciences.

Joseph Mahoney is co-chair of the life sciences group, contributing to the firm's strength in Hatch-Waxman and Patent Office disputes. His life sciences expertise is bolstered by a Doctor of Pharmacy degree. Mahoney was recently active for a pharmaceutical client in patent strategy, licensing and litigation.

Patent attorney Vera Nackovic specializes in strategic counseling for clients in the pharmaceutical, biologics and medical device areas, among others. She was recently active for a major pharmaceutical client in a licensing dispute. New York-based Brian Nolan is well versed in patent litigation, counseling and due diligence. He was also involved in the $74 billion merger for Bristol-Myers Squibb.

Headquartered in Chicago with an additional 25 offices worldwide, Mayer Brown is an international, full-service law firm with a significant presence in the life sciences space. In particular, the firm is noted for its robust antitrust and product liability practice.

Daniel Ring is co-leader of the Chicago office's litigation and dispute resolution practice, as well as co-leader of the firm's product liability and mass torts group. Ring currently represents St Jude Medical and Abbott Laboratories, now combined as one of the world's largest medical device companies, in a matter involving the first-known public effort by a short seller to partner with a cybersecurity research firm to short a stock based on claimed cybersecurity vulnerabilities. St Jude alleges that Muddy Waters and MedSec ran a short-selling scheme by spreading false and misleading information about its devices in order to drive down stock prices and collect the ensuing profits. Ring filed a complaint on St Jude's behalf claiming defamation, Lanham Act violations, deceptive trade practices, and civil conspiracy.

In Washington, DC, Andrew Tauber serves alongside Ring as counsel to St Jude Medical in multiple product liability suits involving claims of alleged defects in its Riata defibrillator leads. The team is also defending the client in a securities class action arising out of alleged misrepresentations.
