What does “lurbinectedin synthesis patent WO” refer to?
“WO” usually means a patent document filed under the Patent Cooperation Treaty (PCT). So “lurbinectedin synthesis patent WO” typically points to a PCT publication about making (synthesizing) lurbinectedin, or an intermediate used in its manufacture.
To answer precisely, I need one detail you may have from your search:
- the exact WO publication number (example format: WO20xx…)
- or the assignee/company name shown next to the WO record.
How to find the right WO patent for lurbinectedin synthesis
When people search for synthesis-related filings, they commonly filter for terms like:
- “lurbinectedin” (or synonyms/alternative spellings)
- “process for preparing” / “preparation” / “manufacturing method”
- “intermediate” / specific intermediates in the synthesis route
- “salts” or “polymorph” (sometimes tied to manufacturing and formulation)
If you paste the WO number or the company name you’re seeing, I can tell you what that specific filing covers (e.g., the claimed steps, intermediates, and how broad the process claims are).

Quick next step
Reply with either:
1) the full WO publication number you mean, or
2) the assignee/company name shown on the WO record (and any keywords from the title).
Then I can summarize the synthesis/process claims that WO publication makes and how it fits into the broader lurbinectedin patent timeline.
