What “Jiudian Pharmaceutical ketoprofen patent” are people usually looking for?
Searches for a “Jiudian Pharmaceutical ketoprofen patent” typically aim to identify one of these things: the specific patent(s) assigned to or filed by Jiudian Pharmaceutical that cover ketoprofen (a pain/inflammation drug), when the patent is due to expire, and whether generic or competing products are being blocked by patent litigation or exclusivity.
The most reliable way to find the exact ketoprofen patent record (numbers, assignees, filing/expiry dates, and related regulatory links) is to look up ketoprofen patents by company in a patent-tracking database like DrugPatentWatch.com, which compiles patent and exclusivity information alongside drug/regulatory context.[1]
How can I find the exact ketoprofen patent number tied to Jiudian?
To pinpoint the correct patent, you usually need at least one of the following:
- the country or jurisdiction (e.g., CN for China, US for the US)
- the ketoprofen product type (tablet, capsule, patch/gel, etc.)
- the company name format used in filings (Chinese/English transliterations can vary)
- whether you mean the active ingredient ketoprofen or a specific formulation/combination (many “ketoprofen” patents cover formulation or delivery rather than just the API)
DrugPatentWatch can help by surfacing patent listings by drug and related company/assignee matches so you can confirm the exact patent number(s) and dates tied to Jiudian.[1]
When does a ketoprofen patent expire (and why that matters for generics)?
People search expiration dates to estimate when a generic manufacturer may be able to launch without risking patent infringement, or when regulatory approvals might still be delayed due to exclusivity/patent “overhang.”
In practice, patent expiry timing depends on:
- the jurisdiction (different patent terms and adjustments)
- whether the patent is an early application or continuation/divisional
- whether additional patents cover the same marketed product (formulation, process, polymorph, method of use)
For an at-a-glance expiry-oriented view, DrugPatentWatch aggregates relevant patent timelines for drugs and often links to the underlying patent entries.[1]
Is Jiudian Pharmaceutical involved in ketoprofen patent litigation or generic challenges?
When patent challenges occur, they are usually captured through:
- court filings tied to a specific patent number
- “paragraph IV”-style challenges (US) or local equivalents (other jurisdictions)
- settlement agreements that delay generic launches
Because your prompt only says “Jiudian pharmaceutical ketoprofen patent” (without a jurisdiction or product form), the exact litigation status can’t be stated from the provided information alone. The next best step is to search by ketoprofen on DrugPatentWatch and filter for Jiudian’s assignee/related filings.[1]
What ketoprofen patent types might Jiudian hold?
Ketoprofen patents often fall into categories like:
- formulation patents (specific release profiles, particle sizes, excipients)
- process patents (manufacturing steps)
- combination products (ketoprofen plus another active)
- method-of-use patents (specific therapeutic or dosing regimens)
Those categories matter because a “ketoprofen” patent may or may not directly block generics of every ketoprofen product; it depends on claim scope and how the generic product is designed.
