Regeneron Celebrates Legal Win: Court Upholds Eylea Medication Patent
Portfolio Pulse from Vandana Singh
Regeneron Pharmaceuticals Inc won a legal battle against Viatris Inc, with the court upholding the patent for Regeneron's eye drug Eylea. The U.S. District Court for the Northern District of West Virginia ruled that Viatris's replica violated Regeneron's patent rights, although some claims were invalidated. The lawsuit, initiated by Regeneron in August 2022, was narrowed down to three patents. Despite the win, Regeneron's shares dropped 2.84% in premarket trading, while Viatris's shares saw a minor decline of 0.19%.

NEGATIVE IMPACT
Regeneron's legal win protects its Eylea drug from Viatris's replica, potentially allowing for a new Eylea HD variant. However, shares fell 2.84% premarket.
Despite the positive outcome of the lawsuit, Regeneron's stock price has declined, which could be due to market expectations already pricing in the win or concerns about other factors affecting the company's performance.

NEGATIVE IMPACT
Viatris's attempt to replicate Regeneron's Eylea was deemed a patent violation, but the company's shares only saw a slight decline of 0.19% premarket.
Viatris's loss in court could hinder its ability to compete in the eye drug market with its biosimilar version. The minor stock price decline suggests that the market may have anticipated this outcome or that investors are focused on other aspects of Viatris's business.
