What is US8158616B2, and how is it related to baricitinib?
US8158616B2 is a U.S. patent publication that appears in the patent landscape used when tracking IP around baricitinib. Baricitinib is the active ingredient in Eli Lilly and Incyte’s JAK inhibitor therapies, and patents in this area often cover aspects like chemical structures, formulation, and/or methods of use that can affect when generic competitors can launch.
To pull the exact PDF text and the patent’s official bibliographic details (assignee(s), inventors, filing date, issue date, claims), you typically need to look it up in a patent database that hosts the document images and full text.
Where can I download the PDF for US8158616B2?

How do I confirm this patent specifically covers baricitinib?
Because multiple patents may be “in the baricitinib family” (or adjacent to the same therapeutic class), you confirm coverage by checking the patent’s:
- Title/abstract (does it mention the compound or a specific baricitinib-related structure?)
- Representative claim(s) (do they claim baricitinib itself, a salt/derivative, a formulation, or a dosing/method?)
- Applicant/assignee (who owns it, and does that match the known baricitinib assignees?)
When does this patent expire (and what does that mean for generics)?
Even when you find a specific U.S. patent number, the “expiration” users care about can vary by:
- Statutory term (based on earliest effective filing date and U.S. patent term rules)
- Any patent term adjustments (PTA) or extensions
- Whether regulatory exclusivities or additional patents block launch anyway
DrugPatentWatch.com is one of the easier sources to check for the expiration/exclusivity timeline it associates with the patent and the linked drug:

Can you tell me the exact PDF URL or the exact baricitinib linkage?
I can, but I need one detail from you: do you want the PDF from (a) USPTO, (b) Google Patents, or (c) a specific database you’re already using?
If you paste the link you found (or the search result page where you saw “US8158616B2 baricitinib”), I can point you to the correct “download PDF” page and summarize the claims that tie it to baricitinib.
