A&O Shearman has experience in a wide range of substantive areas including:
Securities Litigation:
Our securities litigation practice is a core component of our market-leading litigation group. With a deep bench of attorneys focusing on this area of law, we are ready to handle any securities dispute. Through years of success, we have become the go-to counsel for numerous public companies and financial institutions, as well as their officers and directors. We recognize that every securities matter is also a business matter. Each case can potentially pose a significant threat, and – if not handled with the appropriate care and sensitivity – can cause major reputational and financial risks.
White Collar Defense and Global Investigations:
Our preeminent white-collar defense and global investigations practice takes a holistic, coordinated approach to navigating our clients through criminal, regulatory and internal investigations. We have both local depth and global reach, and the majority of our work is cross-border. We bring a deep understanding of the laws of different jurisdictions and investigation practices across the globe, bolstered by the experience and insights from the more than 20 former prosecutors and regulators on our team.
Antitrust Litigation:
Our global antitrust team advises corporates, private equity and financial institutions on their most significant transactions, investigations, and litigation. The breadth and scale of our U.S., U.K., and EU practice together with our global network and industry knowledge makes us uniquely placed to advise on complex multijurisdictional matters involving parallel proceedings and inter-agency co-operation.
M&A Litigation:
We have unparalleled expertise in representing major international companies, investment banks, private equity firms, boards of directors, special committees, and other parties involved in high-stakes transactional litigation. We advise on all aspects of M&A disputes, from pre-deal due diligence, risk assessment and mitigation to post-closing claims and remedies, and shareholder disputes. Our deep expertise in M&A litigation across the globe, including in the Delaware Court of Chancery and state and federal courts across the U.S., distinguishes us in the market.
Complex Commercial Litigation:
We have represented corporations, partnerships, joint ventures, and other entities in a variety of business-related disputes relating to breach of contract, fraud, professional malpractice, business torts, and insurance and reinsurance matters.
Intellectual Property Litigation:
We represent the world’s leading businesses, helping them to invest in and protect their critical intellectual property as well as defending them when plaintiffs allege that they have violated intellectual property rights. Whether developing, acquiring, registering, licensing, or enforcing IP rights – or defending against alleged IP violations – we help our clients to navigate the legal and commercial challenges they face globally.
Employment Litigation:
We handle disputes arising from terminations, team moves, whistleblowing, and trade-restraint matters, as well as allegations of misconduct, discrimination and harassment. We have a track record of delivering successful outcomes whether via obtaining or defending injunctions, resolving claims through mediation or arbitration, or litigating in court or before employment tribunals.
Cybersecurity:
We help multinational organizations identify, mitigate, and manage cyber threats. We work with our clients to build their operational resilience and cyber-readiness with robust, tailored compliance programs and governance processes, which address both their own risks and those posed by their supply chain partners.
Arbitration:
We have decades of experience advising and representing clients in complex cross-border commercial arbitrations and investor-state disputes under the rules of all the leading institutions. We are known for our skill in arbitration-related court proceedings - including multijurisdictional enforcement strategies - ensuring we can take cases from inception to their ultimate conclusion. We also regularly advise on complex issues of public international law.
