What is US7803839B2, and how does it relate to cobimetinib?
US7803839B2 is a US patent that can be cited as part of the intellectual-property landscape around cobimetinib. Cobimetinib is a kinase inhibitor used in oncology regimens, and patents tied to the same drug commonly cover aspects such as chemical matter (specific compounds), salts/solid forms, or formulation and use.
However, the exact “example” or claim elements tied to cobimetinib under US7803839B2 depend on the specific claim language and the patent’s disclosed examples. Without the patent text (claims and example passages), it’s not possible to produce a correct, claim-by-claim “example synthesis” of what the patent says cobimetinib is/does or which preparations/examples correspond to it.
What does “patent example synthesis” usually mean for US patents like this?
When people ask for “example synthesis” in a patent context, they often mean one of these:
- Which experimental examples in the patent correspond to the drug substance (or a close analog).
- How the patent’s example procedures can be mapped to the drug’s chemical identity (e.g., named compound vs. generic formula in the disclosure).
- A condensed description of the synthesis route or preparation steps described in the “Examples” section.
To do this accurately for US7803839B2, the key needed inputs are the patent’s “Examples” (and the claim(s) that are meant to cover cobimetinib) so the synthesis can be summarized without inventing or misattributing details.
How can I generate an accurate synthesis of US7803839B2’s cobimetinib-related examples?
If you paste (or link) either of the following, I can produce a tight “example synthesis” grounded in the actual patent language:
- The relevant “Examples” section text for US7803839B2, and
- The claim(s) that you want connected to cobimetinib (or tell me the claim number(s)).
Then I can produce a faithful summary that:
- Identifies which example compounds align with cobimetinib (by structure description/name).
- Summarizes the stepwise preparation described in those examples.
- Notes any ranges, intermediates, catalysts, solvents, temperatures, and yields exactly as stated.
