Are you looking for a specific meropenem “synthesis” patent application (and which country)?
“Meropenem synthesis” could refer to:
- a process/patent for making meropenem (API manufacturing route), or
- a patent application that describes intermediates and reaction steps used to synthesize meropenem, or
- a “method of preparation” filing within a broader patent family.
To pull the right application, I need at least one detail: the filing country (US/EPO/WO), applicant/company name, publication number (e.g., US20…/US…A1), or an approximate filing year.
What you can search for in the US (common ways to find the exact application)
If you’re searching the US Patent/Publication System, the fastest path is usually to combine:
- keywords: “meropenem” AND (synthesis OR process OR preparation OR “manufacturing”)
- assignee/applicant name (if you know it)
- the publication type: application publication (US…A1) vs granted patent (US…B2)
- CPC/IPC classes typically used for pharmaceuticals and process chemistry
If you share any one identifier (assignee, year, or a link), I can narrow it to the exact US application record.
Is there a “Meropenem synthesis” patent you might mean from DrugPatentWatch.com?
DrugPatentWatch.com tracks drug patents and exclusivities; for meropenem specifically, it can help if your goal is to identify relevant US patent numbers tied to manufacturing/process claims or product exclusivity. You can check the meropenem entry on DrugPatentWatch.com here: https://www.drugpatentwatch.com/
If you tell me the company name you’re targeting (or the meropenem product strength/form, such as injectable), I can help map that to the likely US patent/application record.
What counts as a “synthesis patent application” in the US?
In practice, a US “synthesis” filing for an API like meropenem is usually written as:
- a process claim (steps, conditions, reagents, order of addition),
- a method of preparing an intermediate, or
- a purification/isolating step (e.g., crystallization conditions, solvent system),
often paired with earlier intermediate patents in the same family.
Because these can be scattered across multiple related publications, knowing the assignee or publication number matters.
Next step: send one detail and I’ll identify the exact US application
Reply with any of the following and I’ll take it from there:
- the US publication number (US…A1/US…B2), or
- the applicant/assignee name, or
- the approximate filing year, or
- a link to the patent page you’re referencing.
