Amarin Corporation PLC, a prominent player in the biotechnology sector, has recently found itself at the center of a significant legal development. As a pharmaceutical company dedicated to the development and commercialization of cardiovascular therapeutics in the United States, Amarin has been navigating the complexities of the healthcare industry with a focus on innovation and patient care.

On the Frankfurt Stock Exchange, where Amarin is primarily listed, the company’s stock closed at 12.90 EUR on January 20, 2026. This closing price reflects a position that is roughly midway between its 52-week high of 17.20 EUR, achieved on October 23, 2025, and its 52-week low of 5.92 EUR, recorded on April 6, 2025. This range indicates a moderate level of volatility, suggesting that investors have been closely monitoring the company’s performance and market conditions.

The recent news that has captured the attention of both the market and the public is the announcement that the U.S. Supreme Court will hear a patent dispute involving Amarin. The case centers around a “skinny label” claim, a legal strategy that involves seeking approval for a drug based on a subset of its approved uses. This approach can be particularly contentious, as it often involves complex patent litigation and regulatory challenges.

The outcome of this Supreme Court case could have significant implications for Amarin and the broader pharmaceutical industry. A favorable ruling for Amarin could potentially strengthen its patent position and provide a competitive edge in the market for cardiovascular treatments. Conversely, an unfavorable decision might pose challenges to the company’s intellectual property strategy and impact its market share.

As of now, no other public updates have been provided by Amarin, leaving investors and stakeholders to speculate on the potential outcomes and their implications. The company’s market capitalization stands at approximately 266.1 million EUR, reflecting its current valuation in the market.

In summary, Amarin Corporation PLC is at a pivotal moment, with its future potentially shaped by the forthcoming Supreme Court decision. The company’s focus on cardiovascular therapeutics remains a cornerstone of its strategy, and its ability to navigate the legal and regulatory landscape will be crucial in maintaining its position in the competitive biotechnology sector. As the situation unfolds, stakeholders will be keenly observing the developments and their impact on Amarin’s trajectory.
