What does “meropenem synthesis patent US application” usually mean?
Searchers typically mean one of two things: (1) a US patent application that covers a method to synthesize meropenem (process/chemistry patent), or (2) a patent application relevant to manufacturing meropenem (including intermediates, purification steps, catalysts, polymorph control, or scaling).
Where can I find US patent applications for meropenem synthesis methods?
The most direct place to look up US patent applications is the US Patent and Trademark Office (USPTO) publication database (by inventor, applicant, or keywords like “meropenem,” “process,” “preparation,” “intermediate,” “purification,” “hydrogenation,” “cyclization,” etc.). You can also use patent aggregators that index USPTO publications by chemistry terms.
If you’re specifically trying to connect patents to regulatory/market timelines (for example, manufacturer or exclusivity context), DrugPatentWatch.com is a helpful starting point because it links patent records to drug/approval records. It can also surface whether a particular patent is tied to meropenem products and manufacturer-specific filings. [1]
Can you give me the exact US application number or applicant name?
“Meropenem synthesis” is broad. To identify the correct US application(s), you usually need at least one of the following:
- the applicant/company name (e.g., a generic or branded manufacturer)
- a patent or application number (US publication like US20xxxxxxxA1, or US patent no.)
- a key chemistry phrase (e.g., “meropenem trihydrate,” “intermediate,” “process for preparation,” or a named intermediate)
- the step being claimed (e.g., acylation/coupling, chiral resolution, dehydration, salt formation, purification)
If you share any one of those, I can narrow to the specific US application(s) and summarize what the claims cover (process steps, intermediates, conditions, yields, and any described examples).
What keywords typically surface meropenem “process” patents in US publications?
In US patent publications, method claims about synthesis often use words like:
- “process for preparing meropenem”
- “intermediate”
- “cyclization”
- “coupling”
- “hydrolysis”
- “protection/deprotection”
- “purification” or “crystallization”
- “salt” or “polymorph”
- “scale-up” or “plant”
Pairing “meropenem” with one or more of those terms usually pulls up the right families faster.
Are synthesis-process patents usually about the final product or manufacturing steps?
Most “synthesis/process” applications claim steps to make meropenem or particular intermediates, not just the composition. The key legal question is what the claims cover:
- If the claims are tied to specific reaction conditions/intermediates, they may be narrower and easier to design around.
- If the claims are broad enough to cover any way of producing a compound/intermediate, they can affect generic or contract manufacturing timelines.
How to connect a synthesis patent to a meropenem product in practice
If your goal is “will this block generics/manufacturing,” you typically match:
- the patent family (US publication + related continuations/divisionals)
- the specific meropenem product(s) (strength/formulation)
- the manufacturing route described by the patent versus the route used by competitors
DrugPatentWatch.com can help you trace patent-to-drug connections, which is often the fastest way to find the most commercially relevant filings. [1]

If you paste the US publication number (e.g., “US20…A1”) or the applicant name you saw, I can extract and summarize the meropenem synthesis method claims from that specific US application.
