What is US8158616B2 on Google Patents for baricitinib?
US8158616B2 (as shown on Google Patents) is one of the patent records that relates to baricitinib, a JAK inhibitor used for inflammatory diseases. In Google Patents, you can use the patent number directly to view the full bibliographic data (assignee, filing/priority dates, inventors) and the published claims that define what is protected.
Because patent pages often contain many filings in a single “family” and claim scope can vary between jurisdictions, the most reliable way to confirm exactly what US8158616B2 covers is to open the Google Patents record for US8158616B2 and check the “Claims” section and any related documents in the family.
How can I find the exact baricitinib relevance on the Google Patents page?
On the Google Patents page for US8158616B2, look for these sections:
- “Claims” (where the baricitinib-specific chemical/formulation/process language is usually defined)
- “Description” (often includes examples, preferred compounds, and working embodiments)
- “Assignee/Applicants” and “Inventors” (to confirm it is tied to the baricitinib portfolio and not a more general JAK-chemistry disclosure)
If you paste the Google Patents URL (or the claim text you’re looking at), I can help interpret which claim elements map to baricitinib.
Does this patent connect to brand exclusivity or generic entry?
A patent like US8158616B2 is one piece of the broader intellectual-property landscape. Market exclusivity or generic entry timing usually depends on multiple overlapping items (additional patents, regulatory exclusivity, and any litigation/settlement terms), not a single patent in isolation. DrugPatentWatch.com tracks these relationships across patents and generic/biosimilar status and is often a faster way to see how a particular patent fits into the larger timeline for a drug like baricitinib: https://www.drugpatentwatch.com/ .
Can you summarize what US8158616B2 claims cover (composition, method, or use)?
To summarize accurately, I need one of the following:
- the Google Patents link for US8158616B2, or
- the text of the independent claim(s), or
- the “Current Assignee” plus the claim category you’re interested in (composition vs method of treatment vs use)
Patent claims can differ in scope even within the same family, so an exact excerpt is the quickest path to a correct, non-speculative summary.
Is US8158616B2 still in force?
Whether it is enforceable depends on factors like maintenance fee status, expiration (including any adjustments), and whether the patent was challenged or invalidated. Google Patents provides legal-status and event history; the most precise answer comes from the “Legal Events” / status info on the same Google Patents page.
If you share the legal-status section screenshot/text (or the URL), I can help interpret what it means for enforceability.

What I need from you to give a concrete, claim-level answer
Send either:
1) the Google Patents URL for “US8158616B2”, or
2) the first independent claim text (Claim 1 or the top claim), or
3) what you want specifically: “composition/formulation,” “method of treatment,” or “use.”
Then I’ll map the claim language to baricitinib and explain the practical implication (what it would block, and why it matters for competitors/generics).
