Novartis Wins Entresto Generic-Delay Lawsuit
Novartis won a lawsuit alleging it improperly listed a patent to delay generic competition for Entresto, its heart-failure drug. Judge Liman dismissed the case, agreeing the patent was properly listed. Entresto sales fell 42% to $1.31B in Q1 2026 after patent expiration and generic entry, accounting for 14% of Novartis's prior-year sales.
