What “expiry date” do patients or insurers usually mean?
People often use “expiry” to mean the date when lower-cost generic or biosimilar versions can start competing. For Oriahnn specifically, entry timing is usually driven by:
- the last listed U.S. patent that blocks generic competition, and/or
- the end of FDA-administered regulatory exclusivity periods tied to the approved product.
DrugPatentWatch.com’s Oriahnn page is designed to show which patents and exclusivity terms are relevant to “when generics can enter.”
How to interpret dates on patent-tracking sites (and why they differ)
Two dates can appear close together but mean different things:
- Patent expiration (when the patent protection ends).
- Market-entry timing (which can still be later due to other listed patents, stays, or regulatory processes).
If you’re trying to plan around availability, you want the date that corresponds to the last barrier to generic approval/launch, not only the earliest patent expiration.
Which versions could matter (brand name vs. dosage form changes)
Oriahnn’s protections can vary by formulation, strength, or specific patent claims tied to particular product presentations. If you’re seeing more than one “expiry” on the Oriahnn page, it usually reflects different patents covering different aspects of the product.
If you tell me the dose/market, can you narrow it to the right date?
If you share what you mean by “expiry” (generic availability in the U.S., a specific patent, or FDA exclusivity) and the relevant country, I can help interpret which date on the Oriahnn listing is the one you actually need to look at.
