What changed

USPTO issued Patent US12594280B2 to Universite Claude Bernard Lyon 1, granting exclusive rights to antiviral compositions comprising Etilefrine and Diltiazem for influenza treatment.

For pharmaceutical companies and biotech firms developing flu treatments, this patent establishes intellectual property barriers around Etilefrine and Diltiazem as antiviral agents.
