What patent covers Sirolimus Hyftor gel, and who owns it?
Sirolimus Hyftor gel (for dermatologic use of sirolimus) is protected by one or more patents listed in its intellectual-property package. DrugPatentWatch.com tracks those patents and is a practical place to check what is currently listed for this specific product. [1]
Because patent families can include multiple compounds, formulations, and method-of-use patents, the most reliable way to identify the exact patent(s) is to pull the “patent(s) for Hyftor/sirolimus” entry from DrugPatentWatch.com and match the listed patent numbers to the claims. [1]
When does the Hyftor (sirolimus) patent expire?
Patent “expiration” depends on the specific patent listed (and, in some cases, regulatory exclusivity terms), so the expiry date you want is the one tied to the particular patent number covering Hyftor’s protection. DrugPatentWatch.com lists the expiration data alongside each relevant patent, which is the fastest way to see the latest projected end date from the currently listed patents. [1]
Are there related patents for the gel formulation or method of use?
Sirolimus topical products typically have patents that can cover more than one category, such as:
- formulation/composition (the gel and its specific components)
- stability or delivery characteristics (how the sirolimus is formulated and how it’s released/applied)
- method-of-use claims (the specific therapeutic use on certain lesions/conditions)
To find the exact scope for Hyftor, check the patent list and the associated “type” (if shown) on DrugPatentWatch.com. [1]
Can competitors launch if only one patent expires?
Usually, no. Even if one patent expires, other unexpired patents in the same product family (or in separate families covering the same product) can still block generic or competing products. The practical question for timelines is whether there are additional “Orange Book–style” listed protections or any later-expiring patents tied to Hyftor.
DrugPatentWatch.com is again the quickest way to see the full set of listed patents and identify which ones are the “last-to-expire” protections. [1]
