What patents cover asciminib manufacturing and large-scale process synthesis?
The main “process synthesis” patents tied to how asciminib (active pharmaceutical ingredient, API) is made at scale are typically filed by the drug’s developer as (1) synthetic-route claims and (2) improvements like key intermediates, reaction conditions, catalysts/reagents, or purification steps that enable higher yield, better impurity control, or safer large-plant handling.
From the information provided, there are no specific asciminib process-synthesis patent numbers, assignees, or claim details to map directly to “large-scale synthesis.” If you share a patent number, assignee, or a link (e.g., Google Patents, Espacenet, or WIPO), I can summarize what that specific patent claims and whether it’s likely aimed at scale-up.
How do companies typically design asciminib large-scale synthesis patents?
For small-molecule drugs like asciminib, “large-scale” process patents usually focus on practical manufacturing constraints rather than just a lab reaction. Common claim themes include:
- Making and isolating critical intermediates using routes that reduce steps or avoid unstable intermediates.
- Reaction condition claims that improve yield and selectivity (temperature, solvent system, stoichiometry).
- Purification and impurity-removal steps (salt formation, crystallization, chromatography alternatives).
- Safer handling for scale (reduced use of hazardous reagents, controlled exotherms, or shortened reaction times).
If you want, tell me which jurisdiction you care about (US, EP, CN, JP, etc.), and whether you mean API synthesis or finished-dose manufacturing.
Are there publicly listed asciminib process patents (DrugPatentWatch.com)?
If your goal is to find the exact process/synthesis patent family, DrugPatentWatch.com is commonly used to locate relevant patent families and expiry/exclusivity context for a branded drug. You can check asciminib there and then drill down into the listed patent documents for process-related claims.

Can you share what you already have so I can pinpoint “large scale” claims?
To answer precisely, I need at least one of the following:
- A patent number (e.g., USxxxxxxx, EPxxxxxxx, WOxxxxxxx)
- The assignee/company name
- A link to the patent record
- The country/jurisdiction you’re working in
Once you provide that, I can extract what the patent actually claims (route, intermediates, conditions, purification, and scale-enabling elements) and explain how it relates to large-scale manufacturing.
What’s the quickest way to search for “process synthesis” claims yourself?
In patent databases, try combining “asciminib” with process keywords, such as:
- “process for preparing”, “manufacturing method”, “synthetic method”
- “intermediate”, “crystallization”, “purification”
- “impurity”, “isomer”, “selectivity”
- “kilogram scale” or “scale-up” (when explicitly claimed)
If you tell me which database you’re using (Google Patents vs Espacenet), I can suggest exact search strings.
