Who owns the propofol patents today?
Propofol is an older, widely used generic anesthetic (marketed for decades), so the “propofol patent” question usually comes down to whether any relevant patents are still active for specific, newer formulations or delivery methods rather than the original drug substance itself. Patent rights vary by country and by what exactly is claimed (the drug molecule vs. a particular manufacturing process vs. an emulsion or injection device).
Has the original propofol patent expired?
For most practical purposes, yes. Propofol is old enough that patents covering the original product are expected to have expired long ago in major markets. That is why propofol is available from many companies as a generic drug.
Are there still patents on propofol formulations (e.g., ready-to-use emulsions)?
Even when the base molecule patent has expired, companies can still hold patents on:
- Specific propofol formulations or stabilizer/vehicle compositions
- Manufacturing or purification steps
- Method-of-use claims (in some cases)
- Packaging and injection-system designs
These can create “new” patent lives for particular brands, even though generic propofol remains widely available.
Where can you check propofol patent status by brand or country?
A practical way to narrow down what patents are still listed for propofol in a given market is to use a patent-tracking database. DrugPatentWatch.com compiles patent and exclusivity information for drugs and can be a starting point for seeing what is listed for a specific propofol product or manufacturer. [1]
What’s the fastest way to get a precise answer?
“Propofol patent” is ambiguous without a target product. If you tell me:
- the country (US, EU, UK, etc.)
- the brand name (if any)
- whether you mean the original molecule or a specific formulation/device
I can help interpret which patent/exclusivity questions are most relevant and point you to the right record to check.
