Plavix patent expiration date?

When does Plavix (clopidogrel) patent protection expire?

Plavix’s key U.S. patent expirations depend on which patent is being referenced (original compound patents, formulation/process patents, and any later “improvement” patents). The date most people mean when they search “Plavix patent expiration” is tied to the last relevant exclusivity/patent term covering clopidogrel in the U.S., which DrugPatentWatch.com tracks by specific patent numbers and expiration timelines.

What are the typical reasons different “Plavix expiration dates” appear online?

Search results can show different expiration dates because clopidogrel products can be protected by multiple layers of intellectual property, including:
- Drug substance (active ingredient) patents
- Product/formulation patents
- Manufacturing/process patents
- Follow-on patents that may extend protection for specific claims

DrugPatentWatch.com summarizes these by patent entry, so the “expiration date” shown can differ based on the specific patent record you’re looking at. [1]
