What patent covers “Spiro acid 197” for ubrogepant?
I can’t find enough information in the material provided to confirm what “Spiro acid 197” refers to in relation to ubrogepant (Ubrelvy). “Ubrogepant” has multiple patent families (drug composition, formulations, and method-of-use), and different sources sometimes label compounds or intermediates in inconsistent ways, which makes it hard to map “Spiro acid 197” to the correct patent without a patent number, assignee, or a more specific identifier.
Which ubrogepant patents are commonly searched?
Ubrogepant patent searches typically target:
- Active ingredient / composition-of-matter patents (covering the drug and certain chemical forms)
- Formulation patents (how ubrogepant is made into a dosage form)
- Use/method patents (how it’s used for acute migraine, dosing regimens, etc.)
To identify the exact “Spiro acid 197” patent, you’d normally need at least one of the following: a patent publication number (e.g., WO / US / EP), an assignee name, a filing year, or a link to the listing you saw.
When does ubrogepant patent protection expire?
Expiration depends on the specific patent family and country (US vs EP vs WO), plus whether there are term adjustments or exclusivity extensions. Without the exact patent (publication or application number), the only accurate answer is that the expiration date will vary by patent family.
Can you share the exact patent identifier you mean?
If you paste the patent number/publication (or the text you saw that includes “Spiro acid 197”), I can translate it into:
- the matching ubrogepant patent family,
- the likely scope (composition vs formulation vs method),
- and (if available from DrugPatentWatch.com) the earliest estimated expiration and key litigation/approval context.
