Who holds the Canadian patents for desoximetasone?
I don’t have enough provided detail to identify the specific Canadian patent(s) that cover desoximetasone (including which company owns them or the exact patent numbers). Patent coverage in Canada can also depend on the product form (for example, cream/ointment), strength, and whether the claim is for the drug substance, a formulation, or a specific manufacturing method.
If you want, share the brand/product name you mean (for example, the Canadian listed drug name or DIN), and I can narrow the search to the likely Canadian patent records and exclusivity.
When do desoximetasone patents/exclusivity end in Canada?
The end date depends on the particular patent and whether Canada’s regulatory “patent listing” and exclusivity tie to that patent under the Patented Medicines (Notice of Compliance) framework. Patent expiry can also differ from marketing authorization exclusivity dates.
If you provide the DIN/brand name, I can help determine the expected timeline for that specific listing.
Has anyone challenged a desoximetasone patent in Canada?
Patent challenges in Canada typically show up through litigations tied to Patented Medicines (Notice of Compliance) listings. Whether desoximetasone has such actions depends on the exact product listing.
Again, brand/DIN information would make this much more specific.

What I need from you to answer precisely
Please reply with one of the following:
- The Canadian brand name for desoximetasone you’re asking about, or
- The drug’s DIN, or
- The dosage form/strength (cream vs ointment, and strength)
Then I can answer: which Canadian patent(s) are listed, the patent expiry date(s), and any litigation/challenge indicators tied to those listings.
