Halozyme Therapeutics Inc. Takes Legal Action Against Merck Over Patent Infringement

In a significant development within the biotechnology sector, Halozyme Therapeutics Inc., a prominent player in the health care industry, has initiated a patent infringement lawsuit against Merck. This legal action, announced on April 24, 2025, centers around Merck’s injectable formulation of Keytruda, a leading cancer immunotherapy drug.

Halozyme Therapeutics, known for its innovative platform technology involving recombinant human hyaluronidase, has been at the forefront of developing advanced drug delivery systems. The company’s technology is pivotal in enhancing the efficacy of various pharmaceuticals, including those in the cancer treatment domain.

The lawsuit, filed across multiple platforms including RTTNews, Seeking Alpha, and Investing.com, underscores Halozyme’s commitment to protecting its intellectual property. The company alleges that Merck’s injectable Keytruda infringes on Halozyme’s patents, which are integral to its strategic partnerships and proprietary programs.

As of April 22, 2025, Halozyme’s stock was trading at $58.41 on the Nasdaq, with a market capitalization of approximately $7.26 billion. The company’s financial metrics, including a price-to-earnings ratio of 17.13, reflect its robust position in the biotechnology sector.

This legal move by Halozyme is not just about safeguarding its patents but also about reinforcing its role as a key innovator in drug delivery technologies. The outcome of this lawsuit could have significant implications for both companies and the broader pharmaceutical industry.
