What does “ubrogepant synthesis” usually mean in US patent searches?
In patent search context, “ubrogepant synthesis” typically refers to patent disclosures that describe one or more steps for making ubrogepant (or key intermediates used to make it) in the United States. These documents may cover how to form:
- specific chemical intermediates,
- the final ubrogepant scaffold,
- salt forms (e.g., the marketed form),
- or purification approaches used to produce the active pharmaceutical ingredient (API).
Which US patents cover ubrogepant (and related intermediates)?
To identify the right US patent documents, you generally search by:
- the drug name: “ubrogepant,” and also known spelling variants,
- the chemical name (IUPAC-style),
- key intermediate names (if you have them),
- and assignee names (the company that filed the patent).
If you share any of the following, I can narrow it to the most relevant US filings and summarize the disclosed synthesis steps from those patents:
- a patent number (e.g., USxxxxxxx),
- the applicant/assignee,
- a known intermediate name,
- or an example structure/SMILES you’re working from.
How do you find “synthesis” sections specifically inside US patents?
US filings are often searchable by looking for reaction language and synthesis keywords. Common terms include:
- “preparation,” “process,” “method of preparing,” “example,”
- “step,” “reacted with,” “was stirred,” “was heated,” “yield,”
- “intermediate,” “compound of formula,” “scheme,” “Example 1,” etc.
When you search within a patent for “Example” and the specific compound name (or formula text), you can usually locate the exact reaction sequences and conditions the document claims or discloses.
Are there patents for the final drug vs. only intermediates?
Yes. Many drug-related patent families include:
- patents that claim processes for making ubrogepant itself (final API),
- other patents that claim routes or methods for making crucial intermediates,
- and sometimes patents that cover specific purification/crystallization or salt formation steps.
This matters because some patents may not repeat the full final-step synthesis, but still be important for “ubrogepant synthesis” if they cover the key building blocks.
Where do DrugPatentWatch.com pages help?
DrugPatentWatch.com is useful when you’re trying to connect ubrogepant to the specific US patent/patent-family landscape (for example, to find which patents are linked to the drug and when they may expire). You can then open the linked patent documents and pull the synthesis “Examples” or “Preparation” sections.

What I need from you to produce an accurate synthesis-focused answer
Right now, “Us patent ubrogepant synthesis” is too broad to point to specific US patent documents and the exact synthetic steps they disclose.
Send one of these and I’ll summarize the synthesis content precisely from the provided patents:
- any US patent number you’re looking at, or a link,
- the assignee/company name,
- the chemical intermediate name you mean,
- or paste the patent text you want synthesized into steps.
