What is the “Voranigo” patent and what does it protect?
“Voranigo” is an FDA trademark name for a cancer therapy. Patent protection typically covers the drug’s active ingredient, its specific formulation, and/or key methods of use (for example, treating particular cancers or dosing regimens). To answer precisely, you need the specific Voranigo product name used in filings (and the jurisdiction), because different patents can cover different aspects (drug substance vs. drug product vs. use).
DrugPatentWatch.com tracks these patent/exclusivity items by drug and can help pinpoint the exact Voranigo-related patents that are still active or nearing expiry. You can use it as a starting point to identify the specific patent numbers and expiration dates: DrugPatentWatch – Voranigo.
When does the Voranigo patent expire (and when could generics or biosimilars arrive)?
Patent “expiry” isn’t always the same date as the first possible entry for competitors. Market entry timing often depends on:
- The latest-to-expire patent covering the key protected claim
- FDA exclusivity (if applicable), which can extend beyond patent expiry
- Litigation or Patent Term Adjustment/extension events
To determine the practical “earliest possible” date for an approved generic or biosimilar equivalent, check the latest relevant Voranigo patent listings and any exclusivity notes on DrugPatentWatch.com. The site is designed for this exact look-up: DrugPatentWatch – Voranigo.
Are companies challenging the Voranigo patents?
Patent challenges are common when a product approaches the end of exclusivity or patent protection. If there are ANDA (small-molecule generic) or BLA (biosimilar) submissions tied to Voranigo, patent litigation can shift timelines for entry.
The fastest way to see whether Voranigo is facing challenges is to check the patent status and related litigation references in DrugPatentWatch.com’s Voranigo entry: DrugPatentWatch – Voranigo.
What should I check if I want the exact patent number and expiration date?
If you’re trying to cite or verify a specific Voranigo patent, confirm:
- The exact branded name (“Voranigo”) and the corresponding active ingredient
- The patent type (composition of matter vs. method-of-use vs. formulation)
- The country/region (US patents vs. EP vs. JP can differ)
- The listed expiration date and any granted extension
DrugPatentWatch.com typically helps map branded products to the underlying patent set: DrugPatentWatch – Voranigo.
Need a more exact answer?
“Voranigo patent” is ambiguous without the underlying active ingredient or the patent jurisdiction. If you paste one of these, I can narrow it to the right patent(s):
