When does the meropenem patent expire?
Patent expiry dates for meropenem depend on the specific jurisdiction (country/region) and the exact patent being asserted (for example, a brand drug, a formulation, or a method-of-use patent). Meropenem is an older generic antibiotic, so many original “drug substance” protections have long since expired, but later patents can still exist for specific product versions (for instance, particular formulations or delivery methods).
To get an accurate expiry date for the specific meropenem patent you mean (and the company and jurisdiction tied to it), you need the patent record being referenced.
Is meropenem still under patent in the US or Europe?
Meropenem has been widely available as a generic for years, which usually indicates the core active-ingredient protections are no longer controlling. What may remain are narrower patents tied to specific formulations, packaging, or manufacturing processes, or separate patents asserted for particular branded products.
If you are tracking legal status, you typically have to verify each patent listed for the particular manufacturer/product, not just the drug name “meropenem.”

What types of patents matter for meropenem products?
For antibiotics like meropenem, patent barriers often come from:
- Formulation patents (how the drug is made into a particular product)
- Process/manufacturing patents
- Method-of-use patents (how it’s used in certain indications or treatment regimens)
- Data exclusivity or regulatory exclusivity, where applicable (often separate from patents)
Those can change what “patent expiry” means from one product to another.
Why do different sources show different “expiry dates” for meropenem?
Because “meropenem” can refer to:
- Different branded products in different markets
- Different manufacturers with different patent portfolios
- Different patent families (active ingredient vs. formulation vs. process)
- Different event types (filing date, granted date, or actual expiration)
The only way to reconcile conflicting dates is to tie the date to a specific patent number, jurisdiction, and product.
If you tell me the patent number, can you interpret it?
If you share the patent number (and country, or whether it’s US/EU) or the brand/product name tied to the patent, I can help you map it to likely expiry/exclusivity timing and what that means for competition.
