Verquvo generics — when can they launch?
Verquvo (VERICIGUAT) · Merck & Co. · 18 active US patents · 0 expired
Where Verquvo sits in the generic timeline
Mid-term cliff: earliest active US patent for Verquvo expires in 2031 (~5 years). Generic developers typically begin ANDA bioequivalence studies 3-4 years ahead of this date. Paragraph IV filings + Hatch-Waxman 30-month stays may shift the effective entry by another 18-36 months.
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 — 12 patents
- Composition of Matter — 6 patents
FDA U-codes carved out by Verquvo 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.
