12 Most Litigious Companies in America

In this article, we take a look at the 12 most litigious companies in America. You can skip our detailed analysis of the corporate litigation dynamics in the US and go directly to the 5 Most Litigious Companies in America.

Legal battles have become an expensive and often unavoidable part of the business world, where companies find themselves caught up in disagreements. This results in significant financial losses, disruptions to operations, and continuous legal activity that can harm the company's reputation and how people perceive its brand.

A new study by Acritas, now part of Thomson Reuters, reveals that US companies, on average, spend approximately 0.4% of their revenue on legal services, which is a staggering 166% higher than their global counterparts. 

Lisa Hart Shepherd, chief executive officer of Acritas said this: 

“Generally, the US is a much more litigious country” 

The enormous financial burden cripples companies, particularly smaller ones with limited resources, potentially diverting funds that could otherwise be allocated to innovation, expansion, or employee development. 

In 2012, technology giant Apple Inc. (NASDAQ:AAPL) found itself embroiled in a high-stakes patent infringement lawsuit against Samsung Electronics. After a protracted legal battle, a jury awarded Apple Inc. (NASDAQ:AAPL) over $1 billion in damages, a significant blow to Samsung.

Amidst this landscape, certain courts have gained prominence for their expertise and reputation in resolving complex corporate cases. One such court is the Delaware Chancery Court. Known for its specialized knowledge and experience in corporate law, the Delaware Chancery Court attracts a wide range of litigants, including both large multinational companies and smaller entities. The court's reputation stems from its ability to handle high-stakes disputes efficiently and impartially.

A notable case that highlights the significance of the Delaware Chancery Court is the Twitter acquisition lawsuit. Twitter took legal action against Elon Musk when he backed out of the $44 billion deal to buy the social media company. However, Musk closed the deal and acquired Twitter based on the original agreement before the court's decision. 

Within the litigation industry, trends in trademark, copyright, and patent infringement cases have emerged, influencing law firms and legal advisors. The 2019 Litigation Trends Annual Survey reveals a notable increase in demand for legal advisors, as indicated by a 17% growth in the size of in-house legal teams. This positive trend is accompanied by a minimal 2% decrease in team sizes. Additionally, the quantity of patent litigation cases is often influenced by economic factors, such as the general level of business activity and investment.

These industry trends provide valuable insights into the evolving landscape of litigation and the strategies adopted by companies to navigate legal challenges. As litigation continues to shape the business environment, companies must carefully consider their legal approaches and seek experienced counsel to safeguard their interests.

How Big is the Legal Industry in the US?

The market share of the legal industry in the US is approximately $373 billion. The global market value of the legal industry is $713 billion, with North America accounting for 55% of this share, with Canada having a market size of $19 billion.

Some of the top law firms in the US are Kirkland & Ellis, Latham & Watkins and DLA Piper, among others, with Kirkland & Ellis being the biggest law firm in America.
