What is patent CN110693860A about (ketoprofen)?
CN110693860A is a Chinese patent publication that includes ketoprofen among its subject matter. Based on the publication number alone, you typically need to check the patent’s claims/abstract to confirm exactly what it claims (for example, a specific formulation, polymorph, salt, co-crystal, process, or combination product) and who the assignee is. The exact scope matters because many ketoprofen-related patents cover very different inventions (API form vs. manufacturing method vs. drug product formulation).
If you paste the abstract/claim text (or the assignee and title), I can interpret what the patent is protecting and how it might relate to competing ketoprofen products.
Who owns CN110693860A, and what does it claim?
To determine ownership and the precise legal protection, the key fields to look at inside CN110693860A are:
- Applicant/assignee name(s)
- Title and abstract
- Independent claims (what is protected)
- Dependent claims (what variations are also protected)
- Any example embodiments (often shows what the “invention” really is)
These details are usually decisive for whether the patent could affect generic ketoprofen, an over-the-counter product, a veterinary use, or only a narrow formulation/process.
Does CN110693860A still matter today (status, term, and possible expiration)?
A Chinese patent’s practical impact depends on:
- Whether it was granted (vs. only published)
- The filing date (term typically runs from filing date, with possible adjustments)
- Any later amendments, invalidations, or enforcement actions
- Whether the patent covers a form/process that a manufacturer can avoid by changing manufacturing steps or formulation
To answer “is it still in force,” you need the grant/publication details and status record for CN110693860A.
How to find the exact ketoprofen angle in CN110693860A (fast checklist)
When you open the CN110693860A document, search within it for terms like:
- “ketoprofen” (to see how it is used)
- “salt” / “ester” / “polymorph” / “crystal form” / “amorphous”
- “formulation” / “tablet” / “capsule” / “gel” / “microemulsion”
- “preparation method” / “process”
- “example” sections that describe ingredients and process parameters
- claim keywords like “comprising,” “wherein,” and “characterized in that”
This tells you whether the patent is about the API itself (stronger blocking potential) or about a specific manufacturing/formulation approach (easier to design around).
