Because I don’t have the underlying USPTO text or the specific document links in the information provided here, I can’t directly supply a working PDF link or confirm the exact pages/claims content from this chat. If you tell me which site you want to use (USPTO, Google Patents, Justia, etc.), I can point you to the exact place to click for the PDF once you’re on that page.
How does this relate to cobimetinib?
Cobimetinib is a MEK inhibitor marketed as Cotellic. Patent numbers like US7803839B2 are sometimes associated with drug substance, formulations, synthesis, specific crystalline forms, combination regimens, or related therapeutic methods, but the exact relationship depends on what the claims cover in that specific patent.
If you paste the patent title/abstract (or the key claim summary) from US7803839B2, I can map it to what it likely protects for cobimetinib (for example: method of treatment vs. composition vs. combination).
Is US7803839B2 definitely “the cobimetinib patent”?
Not every patent that appears in cobimetinib-related searches is the core “active ingredient” patent. Large molecule/drug programs typically have multiple patent families covering different aspects of the product and lifecycle (composition of matter, intermediates, polymorphs, dosing regimens, etc.). Without the patent title or claims, it’s not possible to verify whether US7803839B2 is the primary one, an improvement patent, or even indirectly related.
Where else can you cross-check cobimetinib patent status?

You can start from their cobimetinib area if available on the site and then search for “US7803839B2” within the listings:
