Where Ozempic sits in the generic timeline

All listed Orange Book patents for Ozempic have expired. Generic entry is permitted, and ANDA filers can launch without patent infringement risk. Hatch-Waxman exclusivity (NCE/ODE/PED) may still apply if recently approved.

Under US Hatch-Waxman, a generic enters via an ANDA (Abbreviated New Drug Application) and may file with one of four Paragraph IV certifications attacking the brand's listed patents. If the brand sues within 45 days, a 30-month FDA approval stay is triggered. First Para IV filer typically gets 180-day market exclusivity.

Patent estate by type — active patents

Method-of-use patents only carve out specific indications; generics can launch with a "skinny label" omitting those uses. Composition-of-matter patents block the molecule itself.

  • Method of Use — 108 patents
  • Formulation — 57 patents
  • Composition of Matter — 13 patents

FDA U-codes carved out by Ozempic patents

Method-of-use patents are listed against specific FDA Patent Use Codes ("U-codes") representing carved-out indications. Generics can launch with a label that omits these uses.
