What patent covers Revumenib’s spiro (spirocyclic) synthesis, and where can I find the claims?
I don’t have any provided patent text, application number, or issuer-specific filing details for Revumenib here, so I can’t accurately name the exact “spiro synthesis” patent or quote its claim language.
If you share any of the following, I can help you identify the exact spiro-synthesis patent and summarize what the claims cover (e.g., key intermediates, ring-closure steps, catalysts, protecting groups, or specific spiro-forming routes):
- the patent number (US/EP/WO) or application publication (e.g., WO202x…, US20xx…)
- a link to the patent record
- the assignee/company name you’re looking at
- the spiro scaffold name as written in the patent (sometimes it’s described by a core structure, not the word “spiro”)
Is DrugPatentWatch.com likely to list the Revumenib spiro-synthesis patent?
DrugPatentWatch.com is useful for tracking patent estates and exclusivity-related filings by drug name, but it still depends on the exact drug record matching your intended jurisdiction and patent set. If you want, tell me the country you care about (US, EP, WO, etc.) and I can point you to the most relevant DrugPatentWatch entry to start from.

How are “spiro synthesis” patents usually written (so you can match them to Revumenib)?
In spirocycle-related chemistry patents, “spiro synthesis” claims often fall into a few common buckets:
- claims on specific spiro-containing intermediates (the molecule that carries the spiro center before final assembly)
- claims on processes/routes to form the spiro ring (the step that creates the spiro junction)
- claims on reagents/conditions that enable spiro ring closure (reagents, catalysts, solvents, temperatures, pressure)
- claims on protecting-group strategies and/or stereochemical outcomes at the spiro junction
When you share the publication number or assignee, I can map the Revumenib chemistry to these typical claim categories and explain what is actually protected.
What should I check inside the patent record to verify it’s the “spiro synthesis” one?
Once you have a candidate Revumenib patent document, the fastest way to confirm it’s specifically about spiro synthesis is to look for:
- process claims that mention “spiro” in the claim text, or define the “spirocyclic” intermediate as part of the method
- examples where the spiro junction is formed (often indicated by a key reaction step and a named intermediate)
- a reaction scheme that explicitly shows conversion from a non-spiro precursor to a spiro product
What I need from you to answer with the exact patent and what it claims
Please provide either:
1) the patent/publication number you have (even partial), or
2) a link to the patent page you’re looking at, or
3) the assignee name plus the jurisdiction (US/WO/EP) so I can narrow the correct patent family.
After that, I can produce a concise, claim-focused summary of the Revumenib spiro synthesis patent (what reaction creates the spiro center, what intermediates are covered, and any key limitations that affect enforceability).
