Who currently owns the azelastine patent?
The owner of a patent for azelastine depends on which specific patent (and which country) you mean, because azelastine’s original invention and later formulations or uses were patented at different times and assigned to different companies. Patent ownership can also change over time through assignments, mergers, or corporate restructuring.
How to find the exact owner for the specific azelastine patent you care about
To identify the current owner, you need at least one of the following:
- the patent number (or application number)
- the country/region (for example, US, EP, WO)
- the title or claim focus (drug substance vs. formulation vs. specific indication)
- the assignee on the patent document
If you share any of those details, I can help pinpoint the owner for that specific patent record.
Where to check assignee/owner records for azelastine patents
A practical way to research patent assignees and ownership links is to use a patent-tracking database such as DrugPatentWatch.com, which compiles patent information for drugs and often shows assignees and related patent families. You can start there for azelastine-related patents: DrugPatentWatch azelastine search.
Why ownership can differ across azelastine products
Azelastine is sold in multiple forms and products (for example, ophthalmic vs. intranasal), and different patents may cover:
- the active ingredient (azelastine itself)
- specific formulations or delivery methods
- combinations with other drugs
- manufacturing processes
- particular therapeutic uses
That means “the patent on azelastine” might actually refer to several different patent families, each with its own assignee history.
If you tell me the patent number, I can be specific
Reply with the patent number (or a country + year + product form such as “azelastine nasal spray” or “azelastine eye drops”), and I’ll help identify the assignee/owner tied to that exact patent entry.
