Farxiga (dapagliflozin) – U.S. patent status

Patent Key Claim Issue Date Expiration Date Notes
US 9,247,011 Composition‑of‑matter and manufacturing process for dapagliflozin 2016‑08‑02 October 31 2026 This is the most recent, “core” patent covering the drug’s active ingredient and its production.
US 8,040,771 Formulation and dosage‑form patents 2012‑07‑17 November 7 2024 Covers specific tablet formulations used by Gilead.
US 7,485,487 General use of dapagliflozin in diabetes 2010‑03‑30 April 6 2021 Early‑stage patent that has long since expired.

Bottom line: In the United States the last of the key Farxiga patents expires on October 31 2026. Earlier patents (e.g., the formulation patent) are due to expire in 2024–2025.

Why the dates matter

  • Patent expiration → Generic entry: After a patent expires, a generic manufacturer can file an Abbreviated New Drug Application (ANDA) that, once approved, allows a cheaper generic version to be sold.
  • Patent litigation: Sometimes a company can file a “patent challenge” or obtain a “patent infringement settlement” that can delay generic entry even after the statutory expiry.
  • International variation: The expiration dates above are for U.S. patents. Patents in the EU, Canada, or other markets may expire at different times, which can affect where generic competition appears first.

Where to confirm

Resource What you’ll find
U.S. Patent & Trademark Office (USPTO) database Exact filing, issue, and expiration dates for each patent.
FDA’s “Drug Approval Package” for Farxiga Summary of the patent landscape that was considered in the original approval.
Pharmaceutical industry news sites (e.g., FiercePharma, Reuters Pharma) Updates on patent litigation and generic approvals.

If you need the status in a particular country other than the United States, let me know and I can look up the relevant patent numbers and expiration dates for that jurisdiction.
