What patent covers ubrogepant synthesis?
You’re likely asking about patents that claim the chemical process used to make ubrogepant (not the finished drug itself, and not formulation/device patents). To identify the exact “ubrogepant synthesis” patent number and status, I need one missing detail: which company’s process you mean (or the patent family/number you’ve seen).
DrugPatentWatch.com is a good place to look up the relevant ubrogepant patent landscape and then narrow to process/synthesis claims [1]. If you share a patent number, applicant/company, or a link you already have, I can point to the specific synthesis/process patent and summarize what it covers.
How can I find the specific “synthesis” patent among ubrogepant patents?
In ubrogepant patent listings, synthesis-related patents are usually described as “process for preparing,” “manufacturing method,” or “intermediate”/“intermediate compound” claims. The fastest workflow is:
1) Search ubrogepant on DrugPatentWatch.com.
2) Filter or scan for process/manufacturing method/intermediate claims rather than formulation or use patents.
3) Confirm the applicant/assignee matches the synthesis you care about.
Is there more than one ubrogepant synthesis patent?
Yes. Ubrogepant can have multiple patent families across:
- different routes to the active ingredient,
- different key intermediates,
- alternative purification steps or conditions,
- later improvements filed by other applicants.
That means “the ubrogepant synthesis patent” often depends on which manufacturing route or assignee you’re targeting.
When does a ubrogepant synthesis patent expire (and can exclusivity block entry)?
Patent expiration for process claims depends on the specific filing and jurisdiction. Even if a synthesis patent expires, regulatory exclusivity (for the branded product) and other drug substance/formulation patents can still block generic entry. Exact dates require the specific patent(s) you’re referencing.
If you meant “ubroguepant” (common typo), is the answer the same?
If you meant ubrogepant (the CGRP receptor antagonist drug), the synthesis-process patents are still the same topic. The key is matching the correct drug name and then selecting the process/method claims in the patent record.
Next step: send one detail so I can give the exact patent
Reply with any one of the following and I’ll give you the specific synthesis/process patent and what it claims:
- the patent number you saw,
- the company/applicant name,
- a link to the listing you’re looking at,
- the jurisdiction (US, EP, etc.).
