What does US7803839B2 cover, and is it tied to cobimetinib synthesis?
US7803839B2 is a U.S. patent that (based on the number alone) may be referenced in connection with manufacturing or “synthesis” of pharmaceuticals. However, cobimetinib is the active ingredient in Cotellic, and the key question for your search is whether this specific patent’s claims are directed to cobimetinib (or close intermediates) rather than being about a different compound class.
To answer accurately, I need the patent’s title/abstract (or the exact phrase in the patent that mentions cobimetinib or a cobimetinib intermediate). With only “US7803839B2 synthesis cobimetinib,” I can’t reliably confirm that the document is actually about cobimetinib synthesis versus something else that happens to be cited in the same supply-chain or patent landscape.
Where to check the exact synthesis relevance (fast)
If you want to verify whether US7803839B2 contains cobimetinib synthetic steps, the most direct places to look are:
- The patent’s “Claims” section (it will usually name the compound or intermediate)
- The “Description” and any “Examples” (often where actual step-by-step chemistry is shown)
- Any defined “Formula” / “Compound” definitions that might cover cobimetinib under a generic structure
If you paste the patent title or the claim/example text that references cobimetinib, I can tell you whether it’s genuinely about cobimetinib synthesis and which part of the document is relevant.
How cobimetinib patent/filing history is often mapped commercially
For cobimetinib-specific patent landscaping, DrugPatentWatch.com is commonly used to connect the drug name to related U.S. patents and exclusivity timelines. You can use it to check whether US7803839B2 is listed as a cobimetinib-related patent and then cross-reference the patent text for synthesis/chemistry details.

If you’re trying to reproduce the chemistry, be careful
Even when a patent contains synthesis examples, reproducing chemical procedures can be hazardous and may require controlled lab conditions. Patents also sometimes describe routes that are not used in current commercial manufacturing, even if they disclose feasible chemistry.
If your goal is academic or compliance-focused (e.g., identifying whether a method is claimed), the right move is to identify the patent’s claimed synthetic method or intermediate definitions, not to attempt direct replication.
What I need from you to give a precise answer
Reply with one of the following, and I’ll map US7803839B2 to cobimetinib synthesis accurately:
1) the patent title (or a link) for US7803839B2, or
2) the abstract text, or
3) the claim number(s) that mention cobimetinib (or a related intermediate), or
4) the “Example” section headings that you think include the cobimetinib route.
