What does WO2018117152A1 cover (and where is delgocitinib mentioned)?
WO2018117152A1 is a published patent document on the WO (PCT) track. If you’re trying to confirm whether it relates to delgocitinib specifically, the fastest way is to search within the document (or the Google Patents page) for:
- “delgocitinib”
- “GLPG0634” (a related development code that often appears in the same therapeutic area)
- the chemical scaffold/compound name variants used in the claims
Google Patents lets you open the WO publication, then use the in-page text search to verify the exact wording used for the compound and the parts of the process that reference it.
How to find the “process” claims in Google Patents for WO2018117152A1
On Google Patents, published applications like WO2018117152A1 typically include claim sections covering either:
- a synthesis method (reaction steps, intermediates, reagents, conditions), or
- a formulation or manufacturing process, or
- purification/isolation steps (e.g., crystallization, salts, solvent removal).
To focus on the “process patent” content, look for claim headings/phrases such as:
- “A process for preparing …”
- “Method of producing …”
- “The process according to claim …”
- “intermediate”
- “crystallization”
- “purification”
- “salt formation”
If you paste the Google Patents link or the claim text here, I can point out which exact claims correspond to the process steps.
Is WO2018117152A1 actually a delgocitinib manufacturing/synthesis process patent?
“Process patent” can mean different things in searches:
- preparation of the active pharmaceutical ingredient (API),
- preparation of an intermediate that leads to the API,
- specific purification/crystallization conditions,
- formulation/manufacturing for the finished drug product.
For WO publications, you should verify which category it is by checking what the claims say is being made (the API itself versus an intermediate versus a dosage form). Without opening the document text, the safest interpretation is to treat it as “a process patent” only if the claims explicitly describe a method of preparing the delgocitinib compound (or a named intermediate on the delgocitinib route).
What to check next: assignees, inventors, and legal status
On the Google Patents page for WO2018117152A1, useful fields include:
- Assignee/applicant (often identifies the company developing delgocitinib or a related manufacturing entity)
- Inventors (can hint at whether it’s a process chemistry team)
- Priority date(s) (tells you the technology generation)
- “Patent family” (shows related filings in the US/EP/JP, which often include the strongest process claims)
- “Legal status” (whether it’s active, expired, withdrawn, or under challenge)
Those details help you connect the WO document to the real delgocitinib development timeline and whether the process claims are enforceable in particular jurisdictions.
If you want, I can extract the exact process steps—what I need from you
Share either:
1) the Google Patents URL for WO2018117152A1, or
2) the text of the claims that mention a “process” and any references to delgocitinib/intermediates,
and I’ll summarize:
- the specific synthesis/manufacturing steps,
- the key intermediates and conditions claimed,
- what is considered novel in the claims (based on the claim language),
- and how it likely fits into delgocitinib production versus formulation.
