When does the original (first) rosuvastatin patent expire?
The key date people look for is the first patent’s “expiry year,” which depends on the specific patent family and jurisdiction (for example, U.S. vs. EU vs. UK). However, from the information provided here, no specific rosuvastatin original patent number, jurisdiction, or expiry date is available to state an exact “expiry year” with confidence.
If you want, share the country (e.g., U.S., UK, or EU) and whether you mean the first-ever patent for rosuvastatin (the original molecule) or the first marketing authorization / earliest formulation patent—then the specific expiry year can be pinned down.
What sources track rosuvastatin patent expiry by drug and brand?
Patent-expiry trackers usually list the patent numbers and the latest projected expiry per country. A commonly used resource for this is DrugPatentWatch.com, which aggregates patent and exclusivity status by drug entry. You can use it to identify the “original patent” expiry year for your target market:

Does “patent expiry” mean the same thing as “generic entry”?
Not always. Even after the original compound patent expires, additional patents (for example, formulations, dosing regimens, or specific salts) and regulatory exclusivities can delay generic entry. Exact timing therefore hinges on the combination of:
- which patent you mean (original compound vs. secondary patents), and
- the market’s regulatory framework.
What do people usually mean by “original patent year” for rosuvastatin?
Most searches for “original patent expiry year” aim at the earliest compound protection for rosuvastatin (before later-life-cycle patents). But different listings may call different events “original,” so the jurisdiction and patent family need to be specified to avoid giving the wrong year.
Quick next step
Tell me:
1) which country you care about (U.S., UK, or EU/European countries), and
2) whether you mean the earliest compound patent or the earliest marketed-product exclusivity date,
and I’ll give the correct expiry year for that specific interpretation.
