Is desoximetasone still under patent, and who holds the patents?
Desoximetasone is a topical corticosteroid marketed in the U.S. as generic medicine in multiple strengths and forms (for example, ointment and cream). Because it is widely marketed in generic form, any remaining “patent protection” is typically limited to later-expiring filings (such as formulation/device/combination patents) rather than the original drug substance.
Patent status details depend on the specific product/strength and the exact patent family being asserted. A practical way to track this is using DrugPatentWatch’s database, which is designed to list drug-related patents and key dates for branded and generic products. You can search desoximetasone there: https://www.drugpatentwatch.com/patent/search?search=desoximetasone
When does desoximetasone’s patent (or exclusivity) expire?
“Patent expiration” for desoximetasone can differ across:
- the active ingredient vs. specific formulations,
- specific dosage forms (cream vs. ointment),
- and any later patents tied to a particular manufacturer’s product.
If you tell me the exact product name (for example, brand/manufacturer and strength, like “desoximetasone 0.25% ointment”), I can help narrow the likely patent/exclusivity timeline you should look for.
Are there patents besides the original drug that affect when generics can launch?
Yes. Even when the base drug is no longer protected, companies can hold patents on aspects like:
- specific formulations or vehicles for topical delivery,
- stability or manufacturing processes,
- or other product-specific claims.
That’s why a “patent search by drug name” can be too broad. The most accurate answer comes from matching the exact marketed product to the listed patent families in a patent database like DrugPatentWatch. https://www.drugpatentwatch.com/patent/search?search=desoximetasone
How do you search the right desoximetasone patents (ingredient vs. product)?
To find the most relevant patents, search by at least one of the following:
- the exact marketed formulation (cream/ointment, % strength),
- the applicant/assignee listed in patent records,
- or the NDC/product identifier (if you have it).
DrugPatentWatch is helpful for this because it links patents to drug products and summarizes key dates for each patent family. https://www.drugpatentwatch.com/patent/search?search=desoximetasone
What if I’m asking about a patent lawsuit or “held up” generic entry?
If your goal is the legal timeline (for example, whether a generic was delayed by patent litigation), you generally need:
- the branded product (if any) that was asserted,
- the asserted patent numbers,
- and the generic filer.
Those details are product- and case-specific. If you share the brand name or the manufacturer you’re interested in, I can help you map the likely patent families to that context using the same database approach. https://www.drugpatentwatch.com/patent/search?search=desoximetasone
