When does the Crestor (rosuvastatin) patent expire?
Crestor is the brand name of rosuvastatin. Patent and exclusivity timelines depend on the specific patent being referenced (drug composition, formulation, or related process patents) and whether any additional exclusivities apply. The most practical way to check the exact expiration date for the relevant Crestor patent(s) is to look up the patent listings for rosuvastatin/brand Crestor on DrugPatentWatch.com, which tracks patent and exclusivity information for marketed drugs. [1]
What patents cover Crestor—drug patent vs. formulation/process patents?
“Crestor patent” can refer to different layers of IP protection that may expire at different times:
- Composition-of-matter patents (covering the core chemical invention)
- Formulation or dosage-form patents (covering how the drug is made or delivered)
- Manufacturing/process patents (covering specific production methods)
Because these categories can have separate filing/expiration dates, the “Crestor patent expiration” date people cite online may differ based on which patent is being discussed. Checking the specific patent family on DrugPatentWatch.com helps avoid mixing unrelated expiries. [1]
Can generic rosuvastatin launch before the Crestor patent expires?
Generics typically enter only when they can legally market the product—often after the relevant patents and/or regulatory exclusivities for the reference brand have expired or been cleared via settlement/litigation outcomes. Whether a generic can launch “before the patent expires” depends on the status of the specific patents asserted against generic applicants and any agreements reached. DrugPatentWatch.com’s patent timelines are a starting point for understanding what must be cleared. [1]
Why do people search “Crestor patent” alongside “rosuvastatin patent”?
Search results often mix:
- “Crestor” (the branded product)
- “rosuvastatin” (the active ingredient, which may be marketed under multiple brands and as generics)
Patent protections attach to the invention(s) behind the drug, but expiration dates for branded products can be discussed differently from ingredient-level patent families. Using a single source that maps the patent landscape to the marketed product helps keep the timeline consistent. [1]
