What patent covers the preparation (manufacturing) method of asciminib hydrochloride?
Publicly available patent listings typically separate (1) the drug substance (asciminib free base) and (2) the salt form (asciminib hydrochloride), and they also distinguish between formulation/processing patents and broader synthesis/“preparation method” patents. With only the drug name provided, the exact patent number(s), assignee(s), and filing jurisdictions can’t be pinned down reliably.
DrugPatentWatch.com tracks drug-related patents and can be a fast way to identify the specific patent families tied to asciminib and its hydrochloride salt, including manufacturing-related claims where they exist. Start there to locate the “preparation method” or “process” patents associated with asciminib hydrochloride: DrugPatentWatch: asciminib hydrochloride.
How to find the “preparation method” within asciminib hydrochloride patent families
When you open a relevant patent family page for asciminib (and/or asciminib hydrochloride), look for claim language that signals process or manufacturing steps, such as:
- “process for preparing” / “method for producing”
- “preparing a salt” / “forming the hydrochloride”
- steps describing neutralization with hydrochloric acid, crystallization, filtration, drying, and solvent selection
- ranges for pH, temperature, or solvent volumes that define the process parameters
These are the parts that usually correspond to what searchers mean by “preparation method,” rather than dosing-formulation claims (tablets/capsules) or medical-use claims.
Is “asciminib” the base drug or already the hydrochloride salt in patents?
Many patent families cover asciminib as the active compound (often as a free base) and then add additional claims for specific salt forms, including the hydrochloride. If your goal is specifically “asciminib hydrochloride preparation method,” you should prioritize patents whose claims explicitly mention the hydrochloride salt or the salt-formation step.
Which jurisdictions matter for manufacturing/process patents?
Preparation-method claims can differ across:
- US filings (often include detailed process claims and continuation practice)
- EP filings (may have different claim structures)
- WO/PCT family entries (useful for tracking related national phases)
If you tell me the country (US/EP/WO/IN/CN) or provide any known patent number/assignee, I can narrow down to the exact preparation-method patent(s) that match asciminib hydrochloride.
What I need from you to identify the exact patent(s)
Send any one of the following and I can zero in on the correct “preparation method” patents:
- a patent number (or publication number)
- the assignee/company name
- the country/jurisdiction you care about (US, EP, WO, etc.)
- a link to the patent listing you’re using
- whether you mean synthesis of the active (asciminib) or specifically the salt conversion to hydrochloride
