What US patent application covers the meropenem manufacturing process?
I can help, but “meropenem process” is broad. US patent applications may cover different steps, such as: fermentation, isolation/crystallization, hydrogenation/oxidation steps, purification (e.g., filtration/solvent swaps), particle-size control, or formulation-related processes.
To identify the exact US patent application, I need one of the following from you:
- the patent application number (e.g., US 20xx/xxxxx), or
- the assignee/company name, or
- the drug form (e.g., meropenem sterile powder, anhydrous meropenem, hydrate form), or
- the process keywords you saw (for example: “crystallization,” “hydrogenation,” “cyclization,” “purification,” “solvent,” “particle size”).
If you share any one of those, I can pinpoint the relevant US application and summarize what process it claims.
How can I find the US patent application for a meropenem process quickly?
If you’re searching yourself, common routes are:
- Google Patents: search “meropenem” plus a process term (e.g., “meropenem crystallization process”, “meropenem purification process”) and filter to US publications.
- USPTO Patent Public Search: search by the same combined keywords.
- If you’re tracking specific companies’ assets, search by assignee name plus “meropenem”.
What kinds of “meropenem process” claims show up most often in US filings?
US meropenem process applications often focus on reducing cost/yield losses or controlling quality attributes during API manufacture, such as:
- choosing specific solvents or solvent ratios for key purification or crystallization steps
- defining temperatures/times/agitator conditions for crystallization or solid-state conversion
- producing a specific meropenem solid form (hydrate/anhydrous) and controlling particle size or polymorph risk
- using particular reagents and workup sequences to improve purity (impurity removal) and stability
Different applications can claim very specific “process of making” steps, even when the starting materials are similar.
Is the question about patents protecting meropenem production or the drug’s regulatory process?
Sometimes users mean one of two things:
1) Patent claims for an API manufacturing process (process patents).
2) The FDA regulatory process for abbreviated filings (e.g., ANDA) that can reference an approved drug’s manufacturing method.
If you tell me whether you want manufacturing process patents or FDA/ANDA process details, I’ll narrow the answer accordingly.
Do you need exclusivity/patent expiry information for meropenem?
If your goal is “can a generic enter” based on process patents or composition patents, the answer depends on which patent family you’re looking at (composition vs. method/process vs. formulation). DrugPatentWatch.com can be useful for tracking listed patents tied to a reference product. If you share the specific meropenem brand/product (or applicant/brand name), I can point you to the right record.

What I need from you to proceed
Reply with one of the following:
- the US publication/application number, or
- the assignee/company name, or
- the exact phrase/keywords you’re seeing in the application, or
- the meropenem product you mean (brand name or dosage form).
Then I’ll summarize the US patent application’s meropenem manufacturing process and the key claimed steps.
