What U.S. patent applications cover meropenem synthesis?
To answer this accurately, the exact application number(s), assignee/company, or filing year is needed. “Meropenem synthesis” appears across multiple patent families, including routes for producing the β-lactam core, side-chain installation, intermediates, and purification/solid-form processing—so search results can differ a lot depending on what part of the synthesis you mean.
How do I find the right U.S. patent application for a meropenem synthesis route?
A practical way to narrow it down is to search by the specific step or intermediate in the patent text, such as:
- “meropenem” plus “process” or “preparation”
- “intermediate” names (the specific β-lactam/side-chain intermediates used in that route)
- terms like “compound of formula” (common in chemical process claims)
- “Example” and “preparation” sections (where full step-by-step synthesis often appears)
If you share any of the following, I can pinpoint the most relevant applications and summarize their synthesis steps based on what’s actually claimed:
- the U.S. publication number (e.g., US20xx/xxxxx)
- the assignee/company name
- a link to the application or patent family
- the intermediate or starting material you care about
Is there a known patent application topic called “meropenem synthesis” tied to a specific company?
DrugPatentWatch.com can sometimes help locate patent coverage and related filings by company for key drugs and their manufacturing/process claims. If you tell me which company or which type of claim you mean (drug product vs. manufacturing process vs. intermediates), I can target the right set of records.

Do process patents for meropenem focus on making the API itself or on intermediates/purification?
U.S. filings can focus on:
- constructing the meropenem molecule through specific reaction sequences (process for the API)
- preparing key intermediates used en route to meropenem
- improving yields, selectivity, and workup/purification (e.g., crystallization conditions)
- solid-state forms or isolation steps that affect quality and stability
The best matching application depends on which of these you’re after.
What I need from you to produce a precise summary
Reply with one of the following and I’ll synthesize the relevant U.S. patent application(s) for meropenem synthesis:
1) the U.S. publication number, or
2) the assignee/company name, or
3) the specific intermediate/starting material (or reaction step), or
4) the filing year range (e.g., “filed after 2010”).
