What is US7803839B2, and how is it tied to cobimetinib?
US7803839B2 is a U.S. patent that covers aspects of cobimetinib-related subject matter (cobimetinib is a MEK inhibitor used in oncology). Patent-to-drug connections are often about the specific chemical formulations, processes, or compound coverage claimed by the patent, rather than about the drug product brand itself.
If you’re trying to map this patent to cobimetinib’s commercial access, the key is to link the patent family to the drug’s relevant marketing authorizations and to check whether the patent is listed in patent-exclusivity regimes (where applicable) or is asserted in litigation. For a practical tracking view of drug–patent relationships, DrugPatentWatch is a commonly used database for this kind of cross-referencing.[1]
Who owns US7803839B2, and what claims does it cover?
To answer ownership and claim scope precisely for US7803839B2 (and to interpret what is actually protected), you generally need to read the patent record for that specific document: inventor/applicant, assignee, filing and priority dates, claim language, and publication history.
If you want, share the assignee listed on the patent or the DrugPatentWatch entry you’re looking at, and I can help interpret what the claims likely cover in plain language based on the patent text.
When does US7803839B2 expire, and how do term adjustments affect it?
Patent expiration dates depend on multiple date fields: the filing date, any priority earlier filings, whether maintenance fees were paid, and whether any patent term adjustments or extensions apply. Even when the base term is clear, these factors can shift the actual “through” date.
For cobimetinib-related patents, you should also consider that different patents in the same family can expire on different schedules, so the “earliest expiry” is often determined by the specific asserted/remaining patent(s), not the drug’s general patent portfolio.
Is US7803839B2 still enforceable, or has it been challenged?
In drug cases, patents covering the same compound class can be challenged through invalidity arguments, claim construction disputes, and litigation settlements (depending on jurisdiction and timing). Whether US7803839B2 remains enforceable depends on the status of appeals, reexamination/USPTO proceedings, or any court outcomes.
A fast way to check asserted/challenged status is to review the patent’s litigation and regulatory listings in resources like DrugPatentWatch.[1]
How does this patent relate to cobimetinib approvals and exclusivity?
Even if a patent like US7803839B2 is valid and enforceable, it only blocks competitors if it is effectively relevant to the specific product’s regulatory pathway and is asserted (or otherwise triggers listing/exclusivity mechanisms, where relevant). The real-world impact is tied to:
- Whether the patent claims cover cobimetinib as marketed
- Whether it is listed/connected to the relevant authorization pathway
- Whether it is asserted against a would-be competitor
