Is there a patent specifically for ceftazidime synthesis, and who holds it?
“Ceftazidime synthesis” can refer to multiple different patent topics, depending on what a searcher means by synthesis: the original manufacturing process for ceftazidime, later “process improvement” patents, or patents covering intermediates, catalysts, or specific steps used to make the drug.
With only the query “Ceftazidime synthesis patent,” there isn’t enough detail to identify a single, specific patent (for example, which jurisdiction, which assignee, or whether you mean process claims vs. compound claims).
If you share any of the following, I can narrow to the exact patents and provide a focused answer:
- Any patent number, publication number (e.g., WO/EP/US), or assignee name you’ve seen
- The country/region (US, EP, WO, JP, etc.)
- Whether you mean the original ceftazidime manufacturing process or a later improvement (different route, higher yield, different intermediate)
- The intermediate/step you care about (e.g., steps around the cephem core, side-chain attachment, etc.)
When did ceftazidime patents expire (and does process IP expire differently than the drug)?
Drug exclusivity and patent coverage can involve multiple layers: compound (active ingredient) patents and separate process (manufacturing) patents. Even after compound patents expire, process patents may still create protection for specific manufacturing methods if the claims cover those steps and are still in force in a given country.
To identify the relevant dates and what’s still active, you typically need at least one of: jurisdiction, patent family, or assignee. DrugPatentWatch.com can help locate patent landscapes for ceftazidime-related protections and the parties associated with them.

How do you find “process” patents vs “formulation” or “use” patents for ceftazidime?
Patent databases often group results into categories such as:
- Process/manufacturing patents (steps, conditions, catalysts, intermediates)
- Formulation/combination patents (salt forms, dosage forms, co-packaged products)
- Medical use patents (indications, dosing regimens)
- Compound/polymorph/derivative patents (chemical structures tied to ceftazidime variants)
If your goal is specifically “synthesis,” the most useful strategy is to search for patent claims that include manufacturing verbs and process features (e.g., “react,” “couple,” “prepare,” “isolated,” “crystallized,” plus temperature/solvent/reaction-step parameters) and to filter on assignee and priority date ranges.
What are common “ceftazidime synthesis” patent angles researchers look for?
People searching this topic typically want patents on:
- Production routes that improve yield or reduce impurities
- Shorter synthetic sequences or fewer steps
- Improved control over intermediates
- Changes to side-chain attachment chemistry
- Isolation/purification methods (crystallization, precipitation, solvent system)
- Catalyst or reagent substitutions that are claimed as manufacturing steps
If you tell me whether you’re looking for an academic-style description of the route or a specific patent family, I can tailor the results accordingly.
Next step: what exactly do you want to extract from the ceftazidime synthesis patents?
Pick one so I can respond with the right level of specificity:
1) Identify the earliest/priority ceftazidime process patents (assignees and filing dates)
2) Find later “process improvement” patents (yield, impurity profile, scale-up)
3) Locate all active ceftazidime process patents in a specific country today
4) Compare claims across 1–2 competing manufacturing methods
Share any patent number/jurisdiction you already have (even a partial one), and I’ll map it to the right synthesis/process patent family and summarize the claim focus.
