Where Lipitor sits in the generic timeline

Long-dated protection: earliest active US patent for Lipitor extends to 2037 (~11 years out). Generic competition is at least 4 years away. Lifecycle moves (new formulations, label extensions, combination filings) typically execute 18-36 months ahead of cliff.

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.

  • Formulation — 3 patents
  • Method of Use — 2 patents

FDA U-codes carved out by Lipitor 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.
