Humira primary patent expired 2016 source?

Do you mean the US composition-of-matter patent for adalimumab (Humira) or another jurisdiction? And do you want the exact patent number and expiry date, or just a source confirming the expiry around 2016?

If you’d like, I can pull the precise patent numbers and expiry dates from reliable sources. Good sources to check include:
- FDA Purple Book (biologics patent listings for Humira/adalimumab)
- USPTO Patents Full-Text (PatFT) or Patentscope
- Espacenet (European Patent Office)

A quick note: in the US, the primary adalimumab patent did lapse around 2016, but there are many other patents and regulatory exclusivities that affected market protection in different places. Let me know your target jurisdiction and I’ll fetch the exact citation and date.
