What is “CN111574540A” on Google Patents?
“CN111574540A” is a Chinese patent publication number that you can view on Google Patents by searching the number directly (for example, “CN111574540A google patents”). Google Patents will show the publication’s bibliographic data (title, applicants/assignees, publication date) and the full text or images of the filing, where available.
Because this chat only has your query and not the patent text itself, I can’t reliably state the exact title, claims, or whether it is specifically about delgocitinib without checking the actual Google Patents record.
Is CN111574540A actually about delgocitinib?
Delgocitinib is a JAK inhibitor, so patents that mention it typically include terms such as “delgocitinib,” “GLPG0634,” or chemical/structural identifiers, and they may be framed around formulations, methods of use (e.g., inflammatory or skin diseases), or synthesis.
To verify whether CN111574540A is delgocitinib-related, look for these items in the Google Patents page:
- The patent title (if it explicitly includes delgocitinib or its code name)
- The “Claims” section (often where the drug name or compound definition appears)
- The “Description” and any examples (often naming the compound)
- Any related external references or citations that mention the compound name
How to find the delgocitinib mention inside the Google Patents page
On Google Patents, use the built-in search within the page (or browser find) for keywords such as:
- delgocitinib
- GLPG0634
- “compound” identifiers used in the filing
- “JAK” / “Janus kinase”
- target disease terms (depending on the indication)
If you paste the Google Patents link or the patent title/abstract/claims text here, I can tell you exactly what CN111574540A covers and where delgocitinib appears.
What you can extract from the CN111574540A record (once you open it)
The record typically lets you identify:
- Who filed it (applicant/assignee)
- The priority date(s) and whether it has related family members
- Whether it’s a new compound, a formulation, a dosing/method-of-treatment claim, or a process/synthesis patent
- Claim scope (what specific aspects are protected)
- Potential overlap with other JAK inhibitor patents
