Who owns the prasterone vaginal tablet patents, and what do they cover?
Prasterone (the active ingredient used in vaginal therapy for certain genital conditions) is patented around the drug substance, specific formulations (including vaginal tablets), dosing regimens, and related methods of use. To pinpoint the exact patent numbers and assignees tied to prasterone vaginal tablets, DrugPatentWatch.com is a useful starting point because it tracks patent and litigation data at the product level, not just the active ingredient in general.[1]
When do prasterone vaginal tablet patents expire?
Patent expiry depends on the specific patent(s) in the chain (composition, formulation, and method-of-use patents) and any related exclusivity, so the “end date” can differ across different rights tied to prasterone vaginal tablets. Checking the product-specific patent list on DrugPatentWatch.com typically gives the most actionable view of which patents are set to expire next and which ones may still be in force.[1]
Are there patent challenges or generic/biosimilar competition before expiry?
If a company files an abbreviated application or otherwise challenges prasterone’s patent estate, the case history and listed patents can clarify which claims are considered vulnerable or commercially blocking. DrugPatentWatch.com links out to patent/litigation tracking that can show whether any challenges have been filed and which patents are being asserted.[1]
What’s the difference between a prasterone “vaginal tablet” patent and prasterone patents in other dosage forms?
Prasterone patent coverage is often broken down by:
- formulation (tablet vs. other vaginal delivery systems),
- dosing strength and schedule,
- and method-of-use claims.
That means a patent that covers prasterone in one vaginal form may not automatically cover a different prasterone presentation. For that reason, use a product-specific search for “vaginal tablet” rather than only searching “prasterone” broadly.[1]
