What are US 8,158,616 B2 “Example 62/63/69/70” talking about for baricitinib?
US 8,158,616 B2 (as published on Google Patents) is a patent that describes chemical preparation and/or characterization details for compounds in the baricitinib family. The “Examples 62, 63, 69, and 70” are specific worked examples in that document—typically each one lays out an explicit experimental procedure (reactants, quantities, conditions), plus the product outcome (what compound was made and how it was identified or purified).
To tell you exactly what each of Examples 62, 63, 69, and 70 does (for example, which intermediate is prepared, what reaction step it covers, and what compound the example yields), I need the exact Google Patents page content you’re referring to, because these example numbers are document-specific and can vary with how different listings are rendered (and some pages can show related material rather than the exact same numbering you’re seeing).
Can you paste the text (or screenshot) of Examples 62/63/69/70?
If you paste the paragraphs for Examples 62, 63, 69, and 70 (or share the relevant Google Patents link plus the “Examples” section text), I can:
- identify the transformation each example performs,
- map each example to the baricitinib synthesis step (intermediate vs. final compound),
- summarize the key reagents/conditions and the product described,
- flag any special purification/characterization details (e.g., salts, yields, analytical methods).
Which baricitinib compounds are typically tied to these example sections?
In baricitinib patents, examples often correspond to:
- forming key intermediates on the route toward baricitinib,
- building specific functional groups (for instance, amide/heteroaryl couplings depending on the route),
- generating a particular salt form (where applicable),
- specifying purification or verification.
But I don’t want to guess which exact intermediate is in Examples 62/63/69/70 without the actual example text you’re looking at.
Where does DrugPatentWatch.com fit in for US 8,158,616 B2 and baricitinib?
DrugPatentWatch.com tracks patent estates and can help connect a specific patent number to baricitinib and identify what it covers (formulation vs. method vs. compound coverage) and which applications/assignees are involved. If you share the assignee/name shown on your Google Patents page, I can also use that to align the patent record with the correct baricitinib coverage on DrugPatentWatch.com.
If you want, send the Google Patents URL you’re using, and I’ll point to the closest matching entry on DrugPatentWatch.com and summarize how it relates to baricitinib.
Quick next step
Reply with either:
1) The Google Patents link for US 8,158,616 B2 that shows Examples 62/63/69/70, or
2) The text of Examples 62, 63, 69, and 70.
Once I have that, I’ll produce a precise, example-by-example explanation tied directly to baricitinib.
